+- Introduction of basic prometheus metrics
+- Introduction of Traefik based local testing/example environment
+- Support for request IDs to allow request co-ordination of log lines

+## Important Notes
+
+- [GHSA-652x-m2gr-hppm](https://github.com/oauth2-proxy/oauth2-proxy/security/advisories/GHSA-652x-m2gr-hppm) GitLab group authorization stopped working in v7.0.0, the functionality has now been restored, please see the linked advisory for details

+- [#1117](https://github.com/oauth2-proxy/oauth2-proxy/pull/1117) The `--gcp-healthchecks` option is now deprecated. It will be removed in a future release.
+  - To migrate, you can change your application health checks for OAuth2 Proxy to point to
+    the `--ping-path` value.
+  - You can also migrate the user agent based health check using the `--ping-user-agent` option. Set it to `GoogleHC/1.0` to allow health checks on the path `/` from the Google health checker.

+
+
+## Important Notes
+
+- [GHSA-4mf2-f3wh-gvf2](https://github.com/oauth2-proxy/oauth2-proxy/security/advisories/GHSA-4mf2-f3wh-gvf2) The whitelist domain feature has been updated to fix a vulnerability that was identified, please see the linked advisory for details
+- [#964](https://github.com/oauth2-proxy/oauth2-proxy/pull/964) Redirect URL generation will attempt secondary strategies
+  in the priority chain if any fail the `IsValidRedirect` security check. Previously any failures fell back to `/`.
+- [#953](https://github.com/oauth2-proxy/oauth2-proxy/pull/953) Keycloak will now use `--profile-url` if set for the userinfo endpoint
+  instead of `--validate-url`. `--validate-url` will still work for backwards compatibility.
+- [#957](https://github.com/oauth2-proxy/oauth2-proxy/pull/957) To use X-Forwarded-{Proto,Host,Uri} on redirect detection, `--reverse-proxy` must be `true`.
+- [#936](https://github.com/oauth2-proxy/oauth2-proxy/pull/936) `--user-id-claim` option is deprecated and replaced by `--oidc-email-claim`
+- [#630](https://github.com/oauth2-proxy/oauth2-proxy/pull/630) Gitlab projects needs a Gitlab application with the extra `read_api` enabled
+- [#849](https://github.com/oauth2-proxy/oauth2-proxy/pull/849) `/oauth2/auth` `allowed_groups` querystring parameter can be paired with the `allowed-groups` configuration option.
+  - The `allowed_groups` querystring parameter can specify multiple comma delimited groups.
+  - In this scenario, the user must have a group (from their multiple groups) present in both lists to not get a 401 or 403 response code.
+  - Example:
+    - OAuth2-Proxy globally sets the `allowed_groups` as `engineering`.
+    - An application using Kubernetes ingress uses the `/oauth2/auth` endpoint with `allowed_groups` querystring set to `backend`.
+    - A user must have a session with the groups `["engineering", "backend"]` to pass authorization.
+    - Another user with the groups `["engineering", "frontend"]` would fail the querystring authorization portion.
+- [#905](https://github.com/oauth2-proxy/oauth2-proxy/pull/905) Existing sessions from v6.0.0 or earlier are no longer valid. They will trigger a reauthentication.
+- [#826](https://github.com/oauth2-proxy/oauth2-proxy/pull/826) `skip-auth-strip-headers` now applies to all requests, not just those where authentication would be skipped.
+- [#797](https://github.com/oauth2-proxy/oauth2-proxy/pull/797) The behavior of the Google provider Groups restriction changes with this
+  - Either `--google-group` or the new `--allowed-group` will work for Google now (`--google-group` will be used if both are set)
+  - Group membership lists will be passed to the backend with the `X-Forwarded-Groups` header
+  - If you change the list of allowed groups, existing sessions that now don't have a valid group will be logged out immediately.
+    - Previously, group membership was only checked on session creation and refresh.
+- [#789](https://github.com/oauth2-proxy/oauth2-proxy/pull/789) `--skip-auth-route` is (almost) backwards compatible with `--skip-auth-regex`
+  - We are marking `--skip-auth-regex` as DEPRECATED and will remove it in the next major version.
+  - If your regex contains an `=` and you want it for all methods, you will need to add a leading `=` (this is the area where `--skip-auth-regex` doesn't port perfectly)
+- [#575](https://github.com/oauth2-proxy/oauth2-proxy/pull/575) Sessions from v5.1.1 or earlier will no longer validate since they were not signed with SHA1.
+  - Sessions from v6.0.0 or later had a graceful conversion to SHA256 that resulted in no reauthentication
+  - Upgrading from v5.1.1 or earlier will result in a reauthentication
+- [#616](https://github.com/oauth2-proxy/oauth2-proxy/pull/616) Ensure you have configured oauth2-proxy to use the `groups` scope.
+  - The user may be logged out initially as they may not currently have the `groups` claim however after going back through login process wil be authenticated.
+- [#839](https://github.com/oauth2-proxy/oauth2-proxy/pull/839) Enables complex data structures for group claim entries, which are output as Json by default.
+
+## Breaking Changes
+
+- [#964](https://github.com/oauth2-proxy/oauth2-proxy/pull/964) `--reverse-proxy` must be true to trust `X-Forwarded-*` headers as canonical.
+  These are used throughout the application in redirect URLs, cookie domains and host logging logic. These are the headers:
+  - `X-Forwarded-Proto` instead of `req.URL.Scheme`
+  - `X-Forwarded-Host` instead of `req.Host`
+  - `X-Forwarded-Uri` instead of `req.URL.RequestURI()`
+- [#953](https://github.com/oauth2-proxy/oauth2-proxy/pull/953) In config files & envvar configs, `keycloak_group` is now the plural `keycloak_groups`.
+  Flag configs are still `--keycloak-group` but it can be passed multiple times.
+- [#911](https://github.com/oauth2-proxy/oauth2-proxy/pull/911) Specifying a non-existent provider will cause OAuth2-Proxy to fail on startup instead of defaulting to "google".
+- [#797](https://github.com/oauth2-proxy/oauth2-proxy/pull/797) Security changes to Google provider group authorization flow
+  - If you change the list of allowed groups, existing sessions that now don't have a valid group will be logged out immediately.
+    - Previously, group membership was only checked on session creation and refresh.
+- [#722](https://github.com/oauth2-proxy/oauth2-proxy/pull/722) When a Redis session store is configured, OAuth2-Proxy will fail to start up unless connection and health checks to Redis pass
+- [#800](https://github.com/oauth2-proxy/oauth2-proxy/pull/800) Fix import path for v7. The import path has changed to support the go get installation.
+  - You can now `go get github.com/oauth2-proxy/oauth2-proxy/v7` to get the latest `v7` version of OAuth2 Proxy
+  - Import paths for package are now under `v7`, eg `github.com/oauth2-proxy/oauth2-proxy/v7/pkg/<module>`
+- [#753](https://github.com/oauth2-proxy/oauth2-proxy/pull/753) A bug in the Azure provider prevented it from properly passing the configured protected `--resource`
+  via the login url. If this option was used in the past, behavior will change with this release as it will
+  affect the tokens returned by Azure. In the past, the tokens were always for `https://graph.microsoft.com` (the default)
+  and will now be for the configured resource (if it exists, otherwise it will run into errors)
+- [#754](https://github.com/oauth2-proxy/oauth2-proxy/pull/754) The Azure provider now has token refresh functionality implemented. This means that there won't
+  be any redirects in the browser anymore when tokens expire, but instead a token refresh is initiated
+  in the background, which leads to new tokens being returned in the cookies.
+  - Please note that `--cookie-refresh` must be 0 (the default) or equal to the token lifespan configured in Azure AD to make
+    Azure token refresh reliable. Setting this value to 0 means that it relies on the provider implementation
+    to decide if a refresh is required.
+
+## Changes since v6.1.1

-# Docs
+# Website

-This folder contains our Jekyll based docs site which is hosted at
-https://oauth2-proxy.github.io/oauth2-proxy.
+This website is built using [Docusaurus 2](https://v2.docusaurus.io/), a modern static website generator.

-When making changes to this docs site, please test your changes locally:
+## Installation

-```bash
-docs$ make serve
+```console
+yarn install
 ```

-To run the docs site locally you will need Ruby at version 2.5.0 or
-higher and `bundle` (`gem install bundler` if you already have Ruby).
+## Local Development
+
+```console
+yarn start
+```
+
+This command starts a local development server and open up a browser window. Most changes are reflected live without having to restart the server.
+
+## Build
+
+```console
+yarn build
+```
+
+This command generates static content into the `build` directory and can be served using any static contents hosting service.
+
+## Deployment
+
+```console
+GIT_USER=<Your GitHub username> USE_SSH=true yarn deploy
+```
+
+If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the `gh-pages` branch.

+1. Any request passing through the proxy (and not matched by `--skip-auth-regex`) is checked for the proxy's session cookie (`--cookie-name`) (or, if allowed, a JWT token - see `--skip-jwt-bearer-tokens`).
+2. If authentication is required but missing then the user is asked to log in and redirected to the authentication provider (unless it is an Ajax request, i.e. one with `Accept: application/json`, in which case 401 Unauthorized is returned)
+3. After returning from the authentication provider, the oauth tokens are stored in the configured session store (cookie, redis, ...) and a cookie is set
+4. The request is forwarded to the upstream server with added user info and authentication headers (depending on the configuration)
+
+Notice that the proxy also provides a number of useful [endpoints](features/endpoints.md).

+:::note
+OAuth2 Proxy is a community project.
+Maintainers do not work on this project full time, and as such,
+while we endeavour to respond to disclosures as quickly as possible,
+this may take longer than in projects with corporate sponsorship.
+:::
+
+## Security Disclosures
+
+:::important
+If you believe you have found a vulnerability within OAuth2 Proxy or any of its
+dependencies, please do NOT open an issue or PR on GitHub, please do NOT post
+any details publicly.
+:::
+
+Security disclosures MUST be done in private.
+If you have found an issue that you would like to bring to the attention of the
+maintenance team for OAuth2 Proxy, please compose an email and send it to the
+list of maintainers in our [MAINTAINERS](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/MAINTAINERS) file.
+
+Please include as much detail as possible.
+Ideally, your disclosure should include:
+- A reproducible case that can be used to demonstrate the exploit
+- How you discovered this vulnerability
+- A potential fix for the issue (if you have thought of one)
+- Versions affected (if not present in master)
+- Your GitHub ID
+
+### How will we respond to disclosures?
+
+We use [GitHub Security Advisories](https://docs.github.com/en/github/managing-security-vulnerabilities/about-github-security-advisories)
+to privately discuss fixes for disclosed vulnerabilities.
+If you include a GitHub ID with your disclosure we will add you as a collaborator
+for the advisory so that you can join the discussion and validate any fixes
+we may propose.
+
+For minor issues and previously disclosed vulnerabilities (typically for
+dependencies), we may use regular PRs for fixes and forego the security advisory.
+
+Once a fix has been agreed upon, we will merge the fix and create a new release.
+If we have multiple security issues in flight simultaneously, we may delay
+merging fixes until all patches are ready.
+We may also backport the fix to previous releases,
+but this will be at the discretion of the maintainers.

+title: Alpha Configuration
+---
+
+:::warning
+This page contains documentation for alpha features.
+We reserve the right to make breaking changes to the features detailed within this page with no notice.
+
+Options described in this page may be changed, removed, renamed or moved without prior warning.
+Please beware of this before you use alpha configuration options.
+:::
+
+This page details a set of **alpha** configuration options in a new format.
+Going forward we are intending to add structured configuration in YAML format to
+replace the existing TOML based configuration file and flags.
+
+Below is a reference for the structure of the configuration, with
+[AlphaOptions](#alphaoptions) as the root of the configuration.
+
+When using alpha configuration, your config file will look something like below:
+
+```yaml
+upstreams:
+  - id: ...
+    ...
+injectRequestHeaders:
+  - name: ...
+    ...
+injectResponseHeaders:
+  - name: ...
+    ...
+```
+
+Please browse the [reference](#configuration-reference) below for the structure
+of the new configuration format.
+
+## Using Alpha Configuration
+
+To use the new **alpha** configuration, generate a YAML file based on the format
+described in the [reference](#configuration-reference) below.
+
+Provide the path to this file using the `--alpha-config` flag.
+
+:::note
+When using the `--alpha-config` flag, some options are no longer available.
+See [removed options](#removed-options) below for more information.
+:::
+
+### Converting configuration to the new structure
+
+Before adding the new `--alpha-config` option, start OAuth2 Proxy using the
+`convert-config-to-alpha` flag to convert existing configuration to the new format.
+
+```bash
+oauth2-proxy --convert-config-to-alpha --config ./path/to/existing/config.cfg
+```
+
+This will convert any options supported by the new format to YAML and print the
+new configuration to `STDOUT`.
+
+Copy this to a new file, remove any options from your existing configuration
+noted in [removed options](#removed-options) and then start OAuth2 Proxy using
+the new config.
+
+```bash
+oauth2-proxy --alpha-config ./path/to/new/config.yaml --config ./path/to/existing/config.cfg
+```
+
+## Removed options
+
+The following flags/options and their respective environment variables are no
+longer available when using alpha configuration:
+
+<!-- Legacy Upstream FlagSet -->
+- `flush-interval`/`flush_interval`
+- `pass-host-header`/`pass_host_header`
+- `proxy-websockets`/`proxy_websockets`
+- `ssl-upstream-insecure-skip-verify`/`ssl_upstream_insecure_skip_verify`
+- `upstream`/`upstreams`
+
+<!-- Legacy Headers FlagSet -->
+- `pass-basic-auth`/`pass_basic_auth`
+- `pass-access-token`/`pass_access_token`
+- `pass-user-headers`/`pass_user_headers`
+- `pass-authorization-header`/`pass_authorization_header`
+- `set-basic-auth`/`set_basic_auth`
+- `set-xauthrequest`/`set_xauthrequest`
+- `set-authorization-header`/`set_authorization_header`
+- `prefer-email-to-user`/`prefer_email_to_user`
+- `basic-auth-password`/`basic_auth_password`
+- `skip-auth-strip-headers`/`skip_auth_strip_headers`
+
+Attempting to use these options via flags or via config when `--alpha-config`
+set will result in an error.
+
+:::important
+You must remove these options before starting OAuth2 Proxy with `--alpha-config`

+
+:::warning
+This page contains documentation for alpha features.
+We reserve the right to make breaking changes to the features detailed within this page with no notice.
+
+Options described in this page may be changed, removed, renamed or moved without prior warning.
+Please beware of this before you use alpha configuration options.
+:::
+
+This page details a set of **alpha** configuration options in a new format.
+Going forward we are intending to add structured configuration in YAML format to
+replace the existing TOML based configuration file and flags.
+
+Below is a reference for the structure of the configuration, with
+[AlphaOptions](#alphaoptions) as the root of the configuration.
+
+When using alpha configuration, your config file will look something like below:
+
+```yaml
+upstreams:
+  - id: ...
+    ...
+injectRequestHeaders:
+  - name: ...
+    ...
+injectResponseHeaders:
+  - name: ...
+    ...
+```
+
+Please browse the [reference](#configuration-reference) below for the structure
+of the new configuration format.
+
+## Using Alpha Configuration
+
+To use the new **alpha** configuration, generate a YAML file based on the format
+described in the [reference](#configuration-reference) below.
+
+Provide the path to this file using the `--alpha-config` flag.
+
+:::note
+When using the `--alpha-config` flag, some options are no longer available.
+See [removed options](#removed-options) below for more information.
+:::
+
+### Converting configuration to the new structure
+
+Before adding the new `--alpha-config` option, start OAuth2 Proxy using the
+`convert-config-to-alpha` flag to convert existing configuration to the new format.
+
+```bash
+oauth2-proxy --convert-config-to-alpha --config ./path/to/existing/config.cfg
+```
+
+This will convert any options supported by the new format to YAML and print the
+new configuration to `STDOUT`.
+
+Copy this to a new file, remove any options from your existing configuration
+noted in [removed options](#removed-options) and then start OAuth2 Proxy using
+the new config.
+
+```bash
+oauth2-proxy --alpha-config ./path/to/new/config.yaml --config ./path/to/existing/config.cfg
+```
+
+## Removed options
+
+The following flags/options and their respective environment variables are no
+longer available when using alpha configuration:
+
+<!-- Legacy Upstream FlagSet -->
+- `flush-interval`/`flush_interval`
+- `pass-host-header`/`pass_host_header`
+- `proxy-websockets`/`proxy_websockets`
+- `ssl-upstream-insecure-skip-verify`/`ssl_upstream_insecure_skip_verify`
+- `upstream`/`upstreams`
+
+<!-- Legacy Headers FlagSet -->
+- `pass-basic-auth`/`pass_basic_auth`
+- `pass-access-token`/`pass_access_token`

+- `prefer-email-to-user`/`prefer_email_to_user`
+- `basic-auth-password`/`basic_auth_password`
+- `skip-auth-strip-headers`/`skip_auth_strip_headers`
+
+Attempting to use these options via flags or via config when `--alpha-config`
+set will result in an error.
+
+:::important
+You must remove these options before starting OAuth2 Proxy with `--alpha-config`

+title: OAuth Provider Configuration
+---
+
+You will need to register an OAuth application with a Provider (Google, GitHub or another provider), and configure it with Redirect URI(s) for the domain you intend to run `oauth2-proxy` on.
+
+Valid providers are :
+
+- [Google](#google-auth-provider) _default_
+- [Azure](#azure-auth-provider)
+- [Facebook](#facebook-auth-provider)
+- [GitHub](#github-auth-provider)
+- [Keycloak](#keycloak-auth-provider)

+- [Nextcloud](#nextcloud-provider)
+- [DigitalOcean](#digitalocean-auth-provider)
+- [Bitbucket](#bitbucket-auth-provider)
+- [Gitea](#gitea-auth-provider)
+
+The provider can be selected using the `provider` configuration value.
+
+Please note that not all providers support all claims. The `preferred_username` claim is currently only supported by the OpenID Connect provider.
+
+### Google Auth Provider
+
+For Google, the registration steps are:
+
+1.  Create a new project: https://console.developers.google.com/project
+2.  Choose the new project from the top right project dropdown (only if another project is selected)
+3.  In the project Dashboard center pane, choose **"API Manager"**
+4.  In the left Nav pane, choose **"Credentials"**
+5.  In the center pane, choose **"OAuth consent screen"** tab. Fill in **"Product name shown to users"** and hit save.
+6.  In the center pane, choose **"Credentials"** tab.
+    - Open the **"New credentials"** drop down
+    - Choose **"OAuth client ID"**
+    - Choose **"Web application"**
+    - Application name is freeform, choose something appropriate
+    - Authorized JavaScript origins is your domain ex: `https://internal.yourcompany.com`
+    - Authorized redirect URIs is the location of oauth2/callback ex: `https://internal.yourcompany.com/oauth2/callback`
+    - Choose **"Create"**
+7.  Take note of the **Client ID** and **Client Secret**
+
+It's recommended to refresh sessions on a short interval (1h) with `cookie-refresh` setting which validates that the account is still authorized.
+
+#### Restrict auth to specific Google groups on your domain. (optional)
+
+1.  Create a service account: https://developers.google.com/identity/protocols/OAuth2ServiceAccount and make sure to download the json file.
+2.  Make note of the Client ID for a future step.
+3.  Under "APIs & Auth", choose APIs.
+4.  Click on Admin SDK and then Enable API.
+5.  Follow the steps on https://developers.google.com/admin-sdk/directory/v1/guides/delegation#delegate_domain-wide_authority_to_your_service_account and give the client id from step 2 the following oauth scopes:
+
+```
+https://www.googleapis.com/auth/admin.directory.group.readonly
+https://www.googleapis.com/auth/admin.directory.user.readonly
+```
+
+6.  Follow the steps on https://support.google.com/a/answer/60757 to enable Admin API access.
+7.  Create or choose an existing administrative email address on the Gmail domain to assign to the `google-admin-email` flag. This email will be impersonated by this client to make calls to the Admin SDK. See the note on the link from step 5 for the reason why.
+8.  Create or choose an existing email group and set that email to the `google-group` flag. You can pass multiple instances of this flag with different groups
+    and the user will be checked against all the provided groups.
+9.  Lock down the permissions on the json file downloaded from step 1 so only oauth2-proxy is able to read the file and set the path to the file in the `google-service-account-json` flag.
+10. Restart oauth2-proxy.
+
+Note: The user is checked against the group members list on initial authentication and every time the token is refreshed ( about once an hour ).
+
+### Azure Auth Provider
+
+1. Add an application: go to [https://portal.azure.com](https://portal.azure.com), choose **"Azure Active Directory"** in the left menu, select **"App registrations"** and then click on **"New app registration"**.
+2. Pick a name and choose **"Webapp / API"** as application type. Use `https://internal.yourcompany.com` as Sign-on URL. Click **"Create"**.
+3. On the **"Settings"** / **"Properties"** page of the app, pick a logo and select **"Multi-tenanted"** if you want to allow users from multiple organizations to access your app. Note down the application ID. Click **"Save"**.
+4. On the **"Settings"** / **"Required Permissions"** page of the app, click on **"Windows Azure Active Directory"** and then on **"Access the directory as the signed in user"**. Hit **"Save"** and then then on **"Grant permissions"** (you might need another admin to do this).
+5. On the **"Settings"** / **"Reply URLs"** page of the app, add `https://internal.yourcompanycom/oauth2/callback` for each host that you want to protect by the oauth2 proxy. Click **"Save"**.
+6. On the **"Settings"** / **"Keys"** page of the app, add a new key and note down the value after hitting **"Save"**.
+7. Configure the proxy with
+
+```
+   --provider=azure
+   --client-id=<application ID from step 3>
+   --client-secret=<value from step 6>
+```
+
+Note: When using the Azure Auth provider with nginx and the cookie session store you may find the cookie is too large and doesn't get passed through correctly. Increasing the proxy_buffer_size in nginx or implementing the [redis session storage](sessions.md#redis-storage) should resolve this.
+
+### Facebook Auth Provider
+
+1.  Create a new FB App from <https://developers.facebook.com/>
+2.  Under FB Login, set your Valid OAuth redirect URIs to `https://internal.yourcompany.com/oauth2/callback`
+
+### GitHub Auth Provider
+
+1.  Create a new project: https://github.com/settings/developers
+2.  Under `Authorization callback URL` enter the correct url ie `https://internal.yourcompany.com/oauth2/callback`
+
+The GitHub auth provider supports two additional ways to restrict authentication to either organization and optional team level access, or to collaborators of a repository. Restricting by these options is normally accompanied with `--email-domain=*`
+
+NOTE: When `--github-user` is set, the specified users are allowed to login even if they do not belong to the specified org and team or collaborators.
+
+To restrict by organization only, include the following flag:
+
+    -github-org="": restrict logins to members of this organisation
+
+To restrict within an organization to specific teams, include the following flag in addition to `-github-org`:
+
+    -github-team="": restrict logins to members of any of these teams (slug), separated by a comma
+
+If you would rather restrict access to collaborators of a repository, those users must either have push access to a public repository or any access to a private repository:
+
+    -github-repo="": restrict logins to collaborators of this repository formatted as orgname/repo
+
+If you'd like to allow access to users with **read only** access to a **public** repository you will need to provide a [token](https://github.com/settings/tokens) for a user that has write access to the repository. The token must be created with at least the `public_repo` scope:
+
+    -github-token="": the token to use when verifying repository collaborators
+
+To allow a user to login with their username even if they do not belong to the specified org and team or collaborators, separated by a comma
+
+    -github-user="": allow logins by username, separated by a comma
+
+If you are using GitHub enterprise, make sure you set the following to the appropriate url:
+
+    -login-url="http(s)://<enterprise github host>/login/oauth/authorize"
+    -redeem-url="http(s)://<enterprise github host>/login/oauth/access_token"
+    -validate-url="http(s)://<enterprise github host>/api/v3"
+
+### Keycloak Auth Provider
+
+1.  Create new client in your Keycloak with **Access Type** 'confidental' and **Valid Redirect URIs** 'https://internal.yourcompany.com/oauth2/callback'
+2.  Take note of the Secret in the credential tab of the client
+3.  Create a mapper with **Mapper Type** 'Group Membership' and **Token Claim Name** 'groups'.
+
+Make sure you set the following to the appropriate url:
+
+    --provider=keycloak
+    --client-id=<client you have created>
+    --client-secret=<your client's secret>
+    --login-url="http(s)://<keycloak host>/auth/realms/<your realm>/protocol/openid-connect/auth"
+    --redeem-url="http(s)://<keycloak host>/auth/realms/<your realm>/protocol/openid-connect/token"
+    --profile-url="http(s)://<keycloak host>/auth/realms/<your realm>/protocol/openid-connect/userinfo"
+    --validate-url="http(s)://<keycloak host>/auth/realms/<your realm>/protocol/openid-connect/userinfo"
+    --keycloak-group=<first_allowed_user_group>
+    --keycloak-group=<second_allowed_user_group>
+    
+For group based authorization, the optional `--keycloak-group` (legacy) or `--allowed-group` (global standard)
+flags can be used to specify which groups to limit access to.
+
+If these are unset but a `groups` mapper is set up above in step (3), the provider will still
+populate the `X-Forwarded-Groups` header to your upstream server with the `groups` data in the
+Keycloak userinfo endpoint response.
+
+The group management in keycloak is using a tree. If you create a group named admin in keycloak
+you should define the 'keycloak-group' value to /admin.
+
+### GitLab Auth Provider
+
+This auth provider has been tested against Gitlab version 12.X. Due to Gitlab API changes, it may not work for version prior to 12.X (see [994](https://github.com/oauth2-proxy/oauth2-proxy/issues/994)).
+
+Whether you are using GitLab.com or self-hosting GitLab, follow [these steps to add an application](https://docs.gitlab.com/ce/integration/oauth_provider.html). Make sure to enable at least the `openid`, `profile` and `email` scopes, and set the redirect url to your application url e.g. https://myapp.com/oauth2/callback.
+
+If you need projects filtering, add the extra `read_api` scope to your application.
+
+The following config should be set to ensure that the oauth will work properly. To get a cookie secret follow [these steps](./overview.md#generating-a-cookie-secret)
+
+```
+    --provider="gitlab"
+    --redirect-url="https://myapp.com/oauth2/callback" // Should be the same as the redirect url for the application in gitlab
+    --client-id=GITLAB_CLIENT_ID
+    --client-secret=GITLAB_CLIENT_SECRET
+    --cookie-secret=COOKIE_SECRET
+```
+
+Restricting by group membership is possible with the following option:
+
+    --gitlab-group="mygroup,myothergroup": restrict logins to members of any of these groups (slug), separated by a comma
+
+If you are using self-hosted GitLab, make sure you set the following to the appropriate URL:
+
+    --oidc-issuer-url="<your gitlab url>"
+
+### LinkedIn Auth Provider
+
+For LinkedIn, the registration steps are:
+
+1.  Create a new project: https://www.linkedin.com/secure/developer
+2.  In the OAuth User Agreement section:
+    - In default scope, select r_basicprofile and r_emailaddress.
+    - In "OAuth 2.0 Redirect URLs", enter `https://internal.yourcompany.com/oauth2/callback`
+3.  Fill in the remaining required fields and Save.
+4.  Take note of the **Consumer Key / API Key** and **Consumer Secret / Secret Key**
+
+### Microsoft Azure AD Provider
+
+For adding an application to the Microsoft Azure AD follow [these steps to add an application](https://docs.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-app).
+
+Take note of your `TenantId` if applicable for your situation. The `TenantId` can be used to override the default `common` authorization server with a tenant specific server.
+
+### OpenID Connect Provider
+
+OpenID Connect is a spec for OAUTH 2.0 + identity that is implemented by many major providers and several open source projects.
+
+This provider was originally built against CoreOS Dex and we will use it as an example.
+The OpenID Connect Provider (OIDC) can also be used to connect to other Identity Providers such as Okta, an example can be found below.
+
+#### Dex
+
+To configure the OIDC provider for Dex, perform the following steps:
+
+1. Download Dex:
+
+    ```
+    go get github.com/dexidp/dex
+    ```
+
+    See the [getting started guide](https://github.com/coreos/dex/blob/master/Documentation/getting-started.md) for more details.
+
+2. Setup oauth2-proxy with the correct provider and using the default ports and callbacks. Add a configuration block to the `staticClients` section of `examples/config-dev.yaml`:
+
+    ```
+    - id: oauth2-proxy
+    redirectURIs:
+    - 'http://127.0.0.1:4180/oauth2/callback'
+    name: 'oauth2-proxy'
+    secret: proxy
+    ```
+
+3. Launch Dex: from `$GOPATH/github.com/dexidp/dex`, run:
+
+    ```
+    bin/dex serve examples/config-dev.yaml
+    ```
+
+4. In a second terminal, run the oauth2-proxy with the following args:
+
+    ```
+    -provider oidc
+    -provider-display-name "My OIDC Provider"
+    -client-id oauth2-proxy
+    -client-secret proxy
+    -redirect-url http://127.0.0.1:4180/oauth2/callback
+    -oidc-issuer-url http://127.0.0.1:5556/dex
+    -cookie-secure=false
+    -cookie-secret=secret
+    -email-domain kilgore.trout
+    ```
+
+    To serve the current working directory as a web site under the `/static` endpoint, add:
+
+    ```
+    -upstream file://$PWD/#/static/
+    ```
+
+5. Test the setup by visiting http://127.0.0.1:4180 or http://127.0.0.1:4180/static .
+
+See also [our local testing environment](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/contrib/local-environment) for a self-contained example using Docker and etcd as storage for Dex.
+
+#### Okta
+
+To configure the OIDC provider for Okta, perform the following steps:
+
+1. Log in to Okta using an administrative account. It is suggested you try this in preview first, `example.oktapreview.com`
+2. (OPTIONAL) If you want to configure authorization scopes and claims to be passed on to multiple applications,
+you may wish to configure an authorization server for each application. Otherwise, the provided `default` will work.
+* Navigate to **Security** then select **API**
+* Click **Add Authorization Server**, if this option is not available you may require an additional license for a custom authorization server.
+* Fill out the **Name** with something to describe the application you are protecting. e.g. 'Example App'.
+* For **Audience**, pick the URL of the application you wish to protect: https://example.corp.com
+* Fill out a **Description**
+* Add any **Access Policies** you wish to configure to limit application access.
+* The default settings will work for other options.
+[See Okta documentation for more information on Authorization Servers](https://developer.okta.com/docs/guides/customize-authz-server/overview/)
+3. Navigate to **Applications** then select **Add Application**.
+* Select **Web** for the **Platform** setting.
+* Select **OpenID Connect** and click **Create**
+* Pick an **Application Name** such as `Example App`.
+* Set the **Login redirect URI** to `https://example.corp.com`.
+* Under **General** set the **Allowed grant types** to `Authorization Code` and `Refresh Token`.
+* Leave the rest as default, taking note of the `Client ID` and `Client Secret`.
+* Under **Assignments** select the users or groups you wish to access your application.
+4. Create a configuration file like the following:
+
+    ```
+    provider = "oidc"
+    redirect_url = "https://example.corp.com/oauth2/callback"
+    oidc_issuer_url = "https://corp.okta.com/oauth2/abCd1234"
+    upstreams = [
+        "https://example.corp.com"
+    ]
+    email_domains = [
+        "corp.com"
+    ]
+    client_id = "XXXXX"
+    client_secret = "YYYYY"
+    pass_access_token = true
+    cookie_secret = "ZZZZZ"
+    skip_provider_button = true
+    ```
+
+The `oidc_issuer_url` is based on URL from your **Authorization Server**'s **Issuer** field in step 2, or simply https://corp.okta.com .
+The `client_id` and `client_secret` are configured in the application settings.
+Generate a unique `client_secret` to encrypt the cookie.
+
+Then you can start the oauth2-proxy with `./oauth2-proxy --config /etc/example.cfg`
+
+#### Okta - localhost
+
+1. Signup for developer account: https://developer.okta.com/signup/
+2. Create New `Web` Application: https://${your-okta-domain}/dev/console/apps/new
+3. Example Application Settings for localhost:
+   * **Name:** My Web App
+   * **Base URIs:** http://localhost:4180/
+   * **Login redirect URIs:** http://localhost:4180/oauth2/callback
+   * **Logout redirect URIs:** http://localhost:4180/
+   * **Group assignments:** `Everyone`
+   * **Grant type allowed:** `Authorization Code` and `Refresh Token`
+4. Make note of the `Client ID` and `Client secret`, they are needed in a future step
+5. Make note of the **default** Authorization Server Issuer URI from: https://${your-okta-domain}/admin/oauth2/as
+6. Example config file `/etc/localhost.cfg`
+    ```
+    provider = "oidc"
+    redirect_url = "http://localhost:4180/oauth2/callback"
+    oidc_issuer_url = "https://${your-okta-domain}/oauth2/default"
+    upstreams = [
+        "http://0.0.0.0:8080"
+    ]
+    email_domains = [
+        "*"
+    ]
+    client_id = "XXX"
+    client_secret = "YYY"
+    pass_access_token = true
+    cookie_secret = "ZZZ"
+    cookie_secure = false
+    skip_provider_button = true
+    # Note: use the following for testing within a container
+    # http_address = "0.0.0.0:4180"
+    ```
+7. Then you can start the oauth2-proxy with `./oauth2-proxy --config /etc/localhost.cfg`
+
+### login.gov Provider
+
+login.gov is an OIDC provider for the US Government.
+If you are a US Government agency, you can contact the login.gov team through the contact information
+that you can find on https://login.gov/developers/ and work with them to understand how to get login.gov
+accounts for integration/test and production access.
+
+A developer guide is available here: https://developers.login.gov/, though this proxy handles everything
+but the data you need to create to register your application in the login.gov dashboard.
+
+As a demo, we will assume that you are running your application that you want to secure locally on
+http://localhost:3000/, that you will be starting your proxy up on http://localhost:4180/, and that
+you have an agency integration account for testing.
+
+First, register your application in the dashboard.  The important bits are:
+  * Identity protocol:  make this `Openid connect`
+  * Issuer:  do what they say for OpenID Connect.  We will refer to this string as `${LOGINGOV_ISSUER}`.
+  * Public key:  This is a self-signed certificate in .pem format generated from a 2048 bit RSA private key.
+    A quick way to do this is `openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 3650 -nodes -subj '/C=US/ST=Washington/L=DC/O=GSA/OU=18F/CN=localhost'`,
+    The contents of the `key.pem` shall be referred to as `${OAUTH2_PROXY_JWT_KEY}`.
+  * Return to App URL:  Make this be `http://localhost:4180/`
+  * Redirect URIs:  Make this be `http://localhost:4180/oauth2/callback`.
+  * Attribute Bundle:  Make sure that email is selected.
+
+Now start the proxy up with the following options:
+```
+./oauth2-proxy -provider login.gov \
+  -client-id=${LOGINGOV_ISSUER} \
+  -redirect-url=http://localhost:4180/oauth2/callback \
+  -oidc-issuer-url=https://idp.int.identitysandbox.gov/ \
+  -cookie-secure=false \
+  -email-domain=gsa.gov \
+  -upstream=http://localhost:3000/ \
+  -cookie-secret=somerandomstring12341234567890AB \
+  -cookie-domain=localhost \
+  -skip-provider-button=true \
+  -pubjwk-url=https://idp.int.identitysandbox.gov/api/openid_connect/certs \
+  -profile-url=https://idp.int.identitysandbox.gov/api/openid_connect/userinfo \
+  -jwt-key="${OAUTH2_PROXY_JWT_KEY}"
+```
+You can also set all these options with environment variables, for use in cloud/docker environments.
+One tricky thing that you may encounter is that some cloud environments will pass in environment
+variables in a docker env-file, which does not allow multiline variables like a PEM file.
+If you encounter this, then you can create a `jwt_signing_key.pem` file in the top level
+directory of the repo which contains the key in PEM format and then do your docker build.
+The docker build process will copy that file into your image which you can then access by
+setting the `OAUTH2_PROXY_JWT_KEY_FILE=/etc/ssl/private/jwt_signing_key.pem`
+environment variable, or by setting `--jwt-key-file=/etc/ssl/private/jwt_signing_key.pem` on the commandline.
+
+Once it is running, you should be able to go to `http://localhost:4180/` in your browser,
+get authenticated by the login.gov integration server, and then get proxied on to your
+application running on `http://localhost:3000/`.  In a real deployment, you would secure
+your application with a firewall or something so that it was only accessible from the
+proxy, and you would use real hostnames everywhere.
+
+#### Skip OIDC discovery
+
+Some providers do not support OIDC discovery via their issuer URL, so oauth2-proxy cannot simply grab the authorization, token and jwks URI endpoints from the provider's metadata.
+
+In this case, you can set the `--skip-oidc-discovery` option, and supply those required endpoints manually:
+
+```
+    -provider oidc
+    -client-id oauth2-proxy
+    -client-secret proxy
+    -redirect-url http://127.0.0.1:4180/oauth2/callback
+    -oidc-issuer-url http://127.0.0.1:5556
+    -skip-oidc-discovery
+    -login-url http://127.0.0.1:5556/authorize
+    -redeem-url http://127.0.0.1:5556/token
+    -oidc-jwks-url http://127.0.0.1:5556/keys
+    -cookie-secure=false
+    -email-domain example.com
+```
+
+### Nextcloud Provider
+
+The Nextcloud provider allows you to authenticate against users in your
+Nextcloud instance.
+
+When you are using the Nextcloud provider, you must specify the urls via
+configuration, environment variable, or command line argument. Depending
+on whether your Nextcloud instance is using pretty urls your urls may be of the
+form `/index.php/apps/oauth2/*` or `/apps/oauth2/*`.
+
+Refer to the [OAuth2
+documentation](https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/oauth2.html)
+to setup the client id and client secret. Your "Redirection URI" will be
+`https://internalapp.yourcompany.com/oauth2/callback`.
+
+```
+    -provider nextcloud
+    -client-id <from nextcloud admin>
+    -client-secret <from nextcloud admin>
+    -login-url="<your nextcloud url>/index.php/apps/oauth2/authorize"
+    -redeem-url="<your nextcloud url>/index.php/apps/oauth2/api/v1/token"
+    -validate-url="<your nextcloud url>/ocs/v2.php/cloud/user?format=json"
+```
+
+Note: in *all* cases the validate-url will *not* have the `index.php`.
+
+### DigitalOcean Auth Provider
+
+1. [Create a new OAuth application](https://cloud.digitalocean.com/account/api/applications)
+    * You can fill in the name, homepage, and description however you wish.
+    * In the "Application callback URL" field, enter: `https://oauth-proxy/oauth2/callback`, substituting `oauth2-proxy` with the actual hostname that oauth2-proxy is running on. The URL must match oauth2-proxy's configured redirect URL.
+2. Note the Client ID and Client Secret.
+
+To use the provider, pass the following options:
+
+```
+   --provider=digitalocean
+   --client-id=<Client ID>
+   --client-secret=<Client Secret>
+```
+
+ Alternatively, set the equivalent options in the config file. The redirect URL defaults to `https://<requested host header>/oauth2/callback`. If you need to change it, you can use the `--redirect-url` command-line option.
+
+### Bitbucket Auth Provider
+
+1. [Add a new OAuth consumer](https://confluence.atlassian.com/bitbucket/oauth-on-bitbucket-cloud-238027431.html)
+    * In "Callback URL" use `https://<oauth2-proxy>/oauth2/callback`, substituting `<oauth2-proxy>` with the actual hostname that oauth2-proxy is running on.
+    * In Permissions section select:
+        * Account -> Email
+        * Team membership -> Read
+        * Repositories -> Read
+2. Note the Client ID and Client Secret.
+
+To use the provider, pass the following options:
+
+```
+   --provider=bitbucket
+   --client-id=<Client ID>
+   --client-secret=<Client Secret>
+```
+
+The default configuration allows everyone with Bitbucket account to authenticate. To restrict the access to the team members use additional configuration option: `--bitbucket-team=<Team name>`. To restrict the access to only these users who has access to one selected repository use `--bitbucket-repository=<Repository name>`.
+
+
+### Gitea Auth Provider
+
+1. Create a new application: `https://< your gitea host >/user/settings/applications`
+2. Under `Redirect URI` enter the correct URL i.e. `https://<proxied host>/oauth2/callback`
+3. Note the Client ID and Client Secret.
+4. Pass the following options to the proxy:
+
+```
+    --provider="github"
+    --redirect-url="https://<proxied host>/oauth2/callback"
+    --provider-display-name="Gitea"
+    --client-id="< client_id as generated by Gitea >"
+    --client-secret="< client_secret as generated by Gitea >"
+    --login-url="https://< your gitea host >/login/oauth/authorize"
+    --redeem-url="https://< your gitea host >/login/oauth/access_token"
+    --validate-url="https://< your gitea host >/api/v1"
+```
+
+
+## Email Authentication
+
+To authorize by email domain use `--email-domain=yourcompany.com`. To authorize individual email addresses use `--authenticated-emails-file=/path/to/file` with one email per line. To authorize all email addresses use `--email-domain=*`.
+
+## Adding a new Provider
+
+Follow the examples in the [`providers` package](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/providers/) to define a new
+`Provider` instance. Add a new `case` to
+[`providers.New()`](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/providers/providers.go) to allow `oauth2-proxy` to use the
+new `Provider`.

+
+`oauth2-proxy` can be configured via [config file](#config-file), [command line options](#command-line-options) or [environment variables](#environment-variables).
+
+### Generating a Cookie Secret
+
+To generate a strong cookie secret use `python -c 'import os,base64; print(base64.urlsafe_b64encode(os.urandom(16)).decode())'`
+
+### Config File
+
+Every command line argument can be specified in a config file by replacing hyphens (-) with underscores (\_). If the argument can be specified multiple times, the config option should be plural (trailing s).
+
+An example [oauth2-proxy.cfg](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/contrib/oauth2-proxy.cfg.example) config file is in the contrib directory. It can be used by specifying `--config=/etc/oauth2-proxy.cfg`

+\[<a name="footnote2">2</a>\]: When using the `whitelist-domain` option, any domain prefixed with a `.` will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: `example.com:8080`. To allow any port, use `*`: `example.com:*`.
+
+See below for provider specific options
+
+### Upstreams Configuration
+
+`oauth2-proxy` supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as `http://127.0.0.1:8080/` for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide `http://127.0.0.1:8080/some/path/` then it will only be requests that start with `/some/path/` which are forwarded to the upstream.
+
+Static file paths are configured as a file:// URL. `file:///var/www/static/` will serve the files from that directory at `http://[oauth2-proxy url]/var/www/static/`, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. `file:///var/www/static/#/static/` will make `/var/www/static/` available at `http://[oauth2-proxy url]/static/`.
+
+Multiple upstreams can either be configured by supplying a comma separated list to the `--upstream` parameter, supplying the parameter multiple times or providing a list in the [config file](#config-file). When multiple upstreams are used routing to them will be based on the path they are set up with.
+
+### Environment variables
+
+Every command line argument can be specified as an environment variable by
+prefixing it with `OAUTH2_PROXY_`, capitalising it, and replacing hyphens (`-`)
+with underscores (`_`). If the argument can be specified multiple times, the
+environment variable should be plural (trailing `S`).
+
+This is particularly useful for storing secrets outside of a configuration file
+or the command line.
+
+For example, the `--cookie-secret` flag becomes `OAUTH2_PROXY_COOKIE_SECRET`,
+and the `--email-domain` flag becomes `OAUTH2_PROXY_EMAIL_DOMAINS`.
+
+## Logging Configuration
+
+By default, OAuth2 Proxy logs all output to stdout. Logging can be configured to output to a rotating log file using the `--logging-filename` command.
+
+If logging to a file you can also configure the maximum file size (`--logging-max-size`), age (`--logging-max-age`), max backup logs (`--logging-max-backups`), and if backup logs should be compressed (`--logging-compress`).
+
+There are three different types of logging: standard, authentication, and HTTP requests. These can each be enabled or disabled with `--standard-logging`, `--auth-logging`, and `--request-logging`.
+
+Each type of logging has its own configurable format and variables. By default these formats are similar to the Apache Combined Log.
+
+Logging of requests to the `/ping` endpoint (or using `--ping-user-agent`) can be disabled with `--silence-ping-logging` reducing log volume. This flag appends the `--ping-path` to `--exclude-logging-paths`.
+
+### Auth Log Format
+Authentication logs are logs which are guaranteed to contain a username or email address of a user attempting to authenticate. These logs are output by default in the below format:
+
+```
+<REMOTE_ADDRESS> - <REQUEST ID> - <user@domain.com> [19/Mar/2015:17:20:19 -0400] [<STATUS>] <MESSAGE>
+```
+
+The status block will contain one of the below strings:
+
+- `AuthSuccess` If a user has authenticated successfully by any method
+- `AuthFailure` If the user failed to authenticate explicitly
+- `AuthError` If there was an unexpected error during authentication
+
+If you require a different format than that, you can configure it with the `--auth-logging-format` flag.
+The default format is configured as follows:
+
+```
+{{.Client}} - {{.RequestID}} - {{.Username}} [{{.Timestamp}}] [{{.Status}}] {{.Message}}
+```
+
+Available variables for auth logging:
+
+| Variable | Example | Description |
+| --- | --- | --- |
+| Client | 74.125.224.72 | The client/remote IP address. Will use the X-Real-IP header it if exists & reverse-proxy is set to true. |
+| Host  | domain.com | The value of the Host header. |
+| Message | Authenticated via OAuth2 | The details of the auth attempt. |
+| Protocol | HTTP/1.0 | The request protocol. |
+| RequestID | 00010203-0405-4607-8809-0a0b0c0d0e0f | The request ID pulled from the `--request-id-header`. Random UUID if empty |
+| RequestMethod | GET | The request method. |
+| Timestamp | 19/Mar/2015:17:20:19 -0400 | The date and time of the logging event. |
+| UserAgent | - | The full user agent as reported by the requesting client. |
+| Username | username@email.com | The email or username of the auth request. |
+| Status | AuthSuccess | The status of the auth request. See above for details. |
+
+### Request Log Format
+HTTP request logs will output by default in the below format:
+
+```
+<REMOTE_ADDRESS> - <REQUEST ID> - <user@domain.com> [19/Mar/2015:17:20:19 -0400] <HOST_HEADER> GET <UPSTREAM_HOST> "/path/" HTTP/1.1 "<USER_AGENT>" <RESPONSE_CODE> <RESPONSE_BYTES> <REQUEST_DURATION>
+```
+
+If you require a different format than that, you can configure it with the `--request-logging-format` flag.
+The default format is configured as follows:
+
+```
+{{.Client}} - {{.RequestID}} - {{.Username}} [{{.Timestamp}}] {{.Host}} {{.RequestMethod}} {{.Upstream}} {{.RequestURI}} {{.Protocol}} {{.UserAgent}} {{.StatusCode}} {{.ResponseSize}} {{.RequestDuration}}
+```
+
+Available variables for request logging:
+
+| Variable | Example | Description |
+| --- | --- | --- |
+| Client | 74.125.224.72 | The client/remote IP address. Will use the X-Real-IP header it if exists & reverse-proxy is set to true. |
+| Host  | domain.com | The value of the Host header. |
+| Protocol | HTTP/1.0 | The request protocol. |
+| RequestDuration | 0.001 | The time in seconds that a request took to process. |
+| RequestID | 00010203-0405-4607-8809-0a0b0c0d0e0f | The request ID pulled from the `--request-id-header`. Random UUID if empty |
+| RequestMethod | GET | The request method. |
+| RequestURI | "/oauth2/auth" | The URI path of the request. |
+| ResponseSize | 12 | The size in bytes of the response. |
+| StatusCode | 200 | The HTTP status code of the response. |
+| Timestamp | 19/Mar/2015:17:20:19 -0400 | The date and time of the logging event. |
+| Upstream | - | The upstream data of the HTTP request. |
+| UserAgent | - | The full user agent as reported by the requesting client. |
+| Username | username@email.com | The email or username of the auth request. |
+
+### Standard Log Format
+All other logging that is not covered by the above two types of logging will be output in this standard logging format. This includes configuration information at startup and errors that occur outside of a session. The default format is below:
+
+```
+[19/Mar/2015:17:20:19 -0400] [main.go:40] <MESSAGE>
+```
+
+If you require a different format than that, you can configure it with the `--standard-logging-format` flag. The default format is configured as follows:
+
+```
+[{{.Timestamp}}] [{{.File}}] {{.Message}}
+```
+
+Available variables for standard logging:
+
+| Variable | Example | Description |
+| --- | --- | --- |
+| Timestamp | 19/Mar/2015:17:20:19 -0400 | The date and time of the logging event. |
+| File | main.go:40 | The file and line number of the logging statement. |
+| Message | HTTP: listening on 127.0.0.1:4180 | The details of the log statement. |
+
+## Configuring for use with the Nginx `auth_request` directive
+
+The [Nginx `auth_request` directive](http://nginx.org/en/docs/http/ngx_http_auth_request_module.html) allows Nginx to authenticate requests via the oauth2-proxy's `/auth` endpoint, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the request through. For example:
+
+```nginx
+server {
+  listen 443 ssl;
+  server_name ...;
+  include ssl/ssl.conf;
+
+  location /oauth2/ {
+    proxy_pass       http://127.0.0.1:4180;
+    proxy_set_header Host                    $host;
+    proxy_set_header X-Real-IP               $remote_addr;
+    proxy_set_header X-Scheme                $scheme;
+    proxy_set_header X-Auth-Request-Redirect $request_uri;
+    # or, if you are handling multiple domains:
+    # proxy_set_header X-Auth-Request-Redirect $scheme://$host$request_uri;
+  }
+  location = /oauth2/auth {
+    proxy_pass       http://127.0.0.1:4180;
+    proxy_set_header Host             $host;
+    proxy_set_header X-Real-IP        $remote_addr;
+    proxy_set_header X-Scheme         $scheme;
+    # nginx auth_request includes headers but not body
+    proxy_set_header Content-Length   "";
+    proxy_pass_request_body           off;
+  }
+
+  location / {
+    auth_request /oauth2/auth;
+    error_page 401 = /oauth2/sign_in;
+
+    # pass information via X-User and X-Email headers to backend,
+    # requires running with --set-xauthrequest flag
+    auth_request_set $user   $upstream_http_x_auth_request_user;
+    auth_request_set $email  $upstream_http_x_auth_request_email;
+    proxy_set_header X-User  $user;
+    proxy_set_header X-Email $email;
+
+    # if you enabled --pass-access-token, this will pass the token to the backend
+    auth_request_set $token  $upstream_http_x_auth_request_access_token;
+    proxy_set_header X-Access-Token $token;
+
+    # if you enabled --cookie-refresh, this is needed for it to work with auth_request
+    auth_request_set $auth_cookie $upstream_http_set_cookie;
+    add_header Set-Cookie $auth_cookie;
+
+    # When using the --set-authorization-header flag, some provider's cookies can exceed the 4kb
+    # limit and so the OAuth2 Proxy splits these into multiple parts.
+    # Nginx normally only copies the first `Set-Cookie` header from the auth_request to the response,
+    # so if your cookies are larger than 4kb, you will need to extract additional cookies manually.
+    auth_request_set $auth_cookie_name_upstream_1 $upstream_cookie_auth_cookie_name_1;
+
+    # Extract the Cookie attributes from the first Set-Cookie header and append them
+    # to the second part ($upstream_cookie_* variables only contain the raw cookie content)
+    if ($auth_cookie ~* "(; .*)") {
+        set $auth_cookie_name_0 $auth_cookie;
+        set $auth_cookie_name_1 "auth_cookie_name_1=$auth_cookie_name_upstream_1$1";
+    }
+
+    # Send both Set-Cookie headers now if there was a second part
+    if ($auth_cookie_name_upstream_1) {
+        add_header Set-Cookie $auth_cookie_name_0;
+        add_header Set-Cookie $auth_cookie_name_1;
+    }
+
+    proxy_pass http://backend/;
+    # or "root /path/to/site;" or "fastcgi_pass ..." etc
+  }
+}
+```
+
+When you use ingress-nginx in Kubernetes, you MUST use `kubernetes/ingress-nginx` (which includes the Lua module) and the following configuration snippet for your `Ingress`.
+Variables set with `auth_request_set` are not `set`-able in plain nginx config when the location is processed via `proxy_pass` and then may only be processed by Lua.
+Note that `nginxinc/kubernetes-ingress` does not include the Lua module.
+
+```yaml
+nginx.ingress.kubernetes.io/auth-response-headers: Authorization
+nginx.ingress.kubernetes.io/auth-signin: https://$host/oauth2/start?rd=$escaped_request_uri
+nginx.ingress.kubernetes.io/auth-url: https://$host/oauth2/auth
+nginx.ingress.kubernetes.io/configuration-snippet: |
+  auth_request_set $name_upstream_1 $upstream_cookie_name_1;
+
+  access_by_lua_block {
+    if ngx.var.name_upstream_1 ~= "" then
+      ngx.header["Set-Cookie"] = "name_1=" .. ngx.var.name_upstream_1 .. ngx.var.auth_cookie:match("(; .*)")
+    end
+  }
+```
+It is recommended to use `--session-store-type=redis` when expecting large sessions/OIDC tokens (_e.g._ with MS Azure).
+
+You have to substitute *name* with the actual cookie name you configured via --cookie-name parameter. If you don't set a custom cookie name the variable  should be "$upstream_cookie__oauth2_proxy_1" instead of "$upstream_cookie_name_1" and the new cookie-name should be "_oauth2_proxy_1=" instead of "name_1=".
+
+## Configuring for use with the Traefik (v2) `ForwardAuth` middleware
+
+**This option requires `--reverse-proxy` option to be set.**
+
+### ForwardAuth with 401 errors middleware
+
+The [Traefik v2 `ForwardAuth` middleware](https://doc.traefik.io/traefik/middlewares/forwardauth/) allows Traefik to authenticate requests via the oauth2-proxy's `/oauth2/auth` endpoint on every request, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the whole request through. For example, on Dynamic File (YAML) Configuration:
+
+```yaml

+- /oauth2/auth - only returns a 202 Accepted response or a 401 Unauthorized response; for use with the [Nginx `auth_request` directive](../configuration/overview.md#configuring-for-use-with-the-nginx-auth_request-directive)
+
+### Sign out
+
+To sign the user out, redirect them to `/oauth2/sign_out`. This endpoint only removes oauth2-proxy's own cookies, i.e. the user is still logged in with the authentication provider and may automatically re-login when accessing the application again. You will also need to redirect the user to the authentication provider's sign out page afterwards using the `rd` query parameter, i.e. redirect the user to something like (notice the url-encoding!):
+
+```
+/oauth2/sign_out?rd=https%3A%2F%2Fmy-oidc-provider.example.com%2Fsign_out_page
+```
+
+Alternatively, include the redirect URL in the `X-Auth-Request-Redirect` header:
+
+```
+GET /oauth2/sign_out HTTP/1.1
+X-Auth-Request-Redirect: https://my-oidc-provider/sign_out_page
+...
+```
+
+(The "sign_out_page" should be the [`end_session_endpoint`](https://openid.net/specs/openid-connect-session-1_0.html#rfc.section.2.1) from [the metadata](https://openid.net/specs/openid-connect-discovery-1_0.html#ProviderConfig) if your OIDC provider supports Session Management and Discovery.)
+
+BEWARE that the domain you want to redirect to (`my-oidc-provider.example.com` in the example) must be added to the [`--whitelist-domain`](../configuration/overview) configuration option otherwise the redirect will be ignored.

+1. Any request passing through the proxy (and not matched by `--skip-auth-regex`) is checked for the proxy's session cookie (`--cookie-name`) (or, if allowed, a JWT token - see `--skip-jwt-bearer-tokens`).
+2. If authentication is required but missing then the user is asked to log in and redirected to the authentication provider (unless it is an Ajax request, i.e. one with `Accept: application/json`, in which case 401 Unauthorized is returned)
+3. After returning from the authentication provider, the oauth tokens are stored in the configured session store (cookie, redis, ...) and a cookie is set
+4. The request is forwarded to the upstream server with added user info and authentication headers (depending on the configuration)
+
+Notice that the proxy also provides a number of useful [endpoints](features/endpoints.md).

+## Security Disclosures
+
+:::important
+If you believe you have found a vulnerability within OAuth2 Proxy or any of its
+dependencies, please do NOT open an issue or PR on GitHub, please do NOT post any
+details publicly.
+:::
+
+Security disclosures MUST be done in private.
+If you have found an issue that you would like to bring to the attention of the
+maintenance team for OAuth2 Proxy, please compose an email and send it to the
+list of maintainers in our [MAINTAINERS](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/MAINTAINERS) file.
+
+Please include as much detail as possible.
+Ideally, your disclosure should include:
+- A reproducible case that can be used to demonstrate the exploit
+- How you discovered this vulnerability
+- A potential fix for the issue (if you have thought of one)
+- Versions affected (if not present in master)
+- Your GitHub ID
+
+### How will we respond to disclosures?
+
+We use [GitHub Security Advisories](https://docs.github.com/en/github/managing-security-vulnerabilities/about-github-security-advisories)
+to privately discuss fixes for disclosed vulnerabilities.
+If you include a GitHub ID with your disclosure we will add you as a collaborator
+for the advisory so that you can join the discussion and validate any fixes
+we may propose.
+
+For minor issues and previously disclosed vulnerabilities (typically for
+dependencies), we may use regular PRs for fixes and forego the security advisory.
+
+Once a fix has been agreed upon, we will merge the fix and create a new release.
+If we have multiple security issues in flight simultaneously, we may delay
+merging fixes until all patches are ready.
+We may also backport the fix to previous releases,
+but this will be at the discretion of the maintainers.

+title: Session Storage
+---
+
+Sessions allow a user's authentication to be tracked between multiple HTTP
+requests to a service.
+
+The OAuth2 Proxy uses a Cookie to track user sessions and will store the session
+data in one of the available session storage backends.
+
+At present the available backends are (as passed to `--session-store-type`):
+- [cookie](#cookie-storage) (default)
+- [redis](#redis-storage)
+
+### Cookie Storage
+
+The Cookie storage backend is the default backend implementation and has
+been used in the OAuth2 Proxy historically.
+
+With the Cookie storage backend, all session information is stored in client
+side cookies and transferred with each and every request.
+
+The following should be known when using this implementation:
+- Since all state is stored client side, this storage backend means that the OAuth2 Proxy is completely stateless
+- Cookies are signed server side to prevent modification client-side
+- It is mandatory to set a `cookie-secret` which will ensure data is encrypted within the cookie data.
+- Since multiple requests can be made concurrently to the OAuth2 Proxy, this session implementation
+cannot lock sessions and while updating and refreshing sessions, there can be conflicts which force
+users to re-authenticate
+
+
+### Redis Storage
+
+The Redis Storage backend stores sessions, encrypted, in redis. Instead sending all the information
+back the the client for storage, as in the [Cookie storage](#cookie-storage), a ticket is sent back
+to the user as the cookie value instead.
+
+A ticket is composed as the following:
+
+`{CookieName}-{ticketID}.{secret}`
+
+Where:
+
+- The `CookieName` is the OAuth2 cookie name (_oauth2_proxy by default)
+- The `ticketID` is a 128 bit random number, hex-encoded
+- The `secret` is a 128 bit random number, base64url encoded (no padding). The secret is unique for every session.
+- The pair of `{CookieName}-{ticketID}` comprises a ticket handle, and thus, the redis key
+to which the session is stored. The encoded session is encrypted with the secret and stored
+in redis via the `SETEX` command.
+
+Encrypting every session uniquely protects the refresh/access/id tokens stored in the session from
+disclosure.
+
+#### Usage
+
+When using the redis store, specify `--session-store-type=redis` as well as the Redis connection URL, via
+`--redis-connection-url=redis://host[:port][/db-number]`.
+
+You may also configure the store for Redis Sentinel. In this case, you will want to use the
+`--redis-use-sentinel=true` flag, as well as configure the flags `--redis-sentinel-master-name`
+and `--redis-sentinel-connection-urls` appropriately.
+
+Redis Cluster is available to be the backend store as well. To leverage it, you will need to set the
+`--redis-use-cluster=true` flag, and configure the flags `--redis-cluster-connection-urls` appropriately.
+
+Note that flags `--redis-use-sentinel=true` and `--redis-use-cluster=true` are mutually exclusive.

+
+There are two recommended configurations.
+
+1.  Configure SSL Termination with OAuth2 Proxy by providing a `--tls-cert-file=/path/to/cert.pem` and `--tls-key-file=/path/to/cert.key`.
+
+    The command line to run `oauth2-proxy` in this configuration would look like this:
+
+    ```bash
+    ./oauth2-proxy \
+        --email-domain="yourcompany.com"  \
+        --upstream=http://127.0.0.1:8080/ \
+        --tls-cert-file=/path/to/cert.pem \
+        --tls-key-file=/path/to/cert.key \
+        --cookie-secret=... \
+        --cookie-secure=true \
+        --provider=... \
+        --client-id=... \
+        --client-secret=...
+    ```
+
+2.  Configure SSL Termination with [Nginx](http://nginx.org/) (example config below), Amazon ELB, Google Cloud Platform Load Balancing, or ....
+
+    Because `oauth2-proxy` listens on `127.0.0.1:4180` by default, to listen on all interfaces (needed when using an
+    external load balancer like Amazon ELB or Google Platform Load Balancing) use `--http-address="0.0.0.0:4180"` or
+    `--http-address="http://:4180"`.
+
+    Nginx will listen on port `443` and handle SSL connections while proxying to `oauth2-proxy` on port `4180`.
+    `oauth2-proxy` will then authenticate requests for an upstream application. The external endpoint for this example
+    would be `https://internal.yourcompany.com/`.
+
+    An example Nginx config follows. Note the use of `Strict-Transport-Security` header to pin requests to SSL
+    via [HSTS](http://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security):
+
+    ```
+    server {
+        listen 443 default ssl;
+        server_name internal.yourcompany.com;
+        ssl_certificate /path/to/cert.pem;
+        ssl_certificate_key /path/to/cert.key;
+        add_header Strict-Transport-Security max-age=2592000;
+
+        location / {
+            proxy_pass http://127.0.0.1:4180;
+            proxy_set_header Host $host;
+            proxy_set_header X-Real-IP $remote_addr;
+            proxy_set_header X-Scheme $scheme;
+            proxy_connect_timeout 1;

+            proxy_read_timeout 30;
+        }
+    }
+    ```
+
+    The command line to run `oauth2-proxy` in this configuration would look like this:
+
+    ```bash
+    ./oauth2-proxy \
+       --email-domain="yourcompany.com"  \
+       --upstream=http://127.0.0.1:8080/ \
+       --cookie-secret=... \

+| ----- | ---- | ----------- |
+| `id` | _string_ | ID should be a unique identifier for the upstream.<br/>This value is required for all upstreams. |
+| `path` | _string_ | Path is used to map requests to the upstream server.<br/>The closest match will take precedence and all Paths must be unique. |
+| `uri` | _string_ | The URI of the upstream server. This may be an HTTP(S) server of a File<br/>based URL. It may include a path, in which case all requests will be served<br/>under that path.<br/>Eg:<br/>- http://localhost:8080<br/>- https://service.localhost<br/>- https://service.localhost/path<br/>- file://host/path<br/>If the URI's path is "/base" and the incoming request was for "/dir",<br/>the upstream request will be for "/base/dir". |
+| `insecureSkipTLSVerify` | _bool_ | InsecureSkipTLSVerify will skip TLS verification of upstream HTTPS hosts.<br/>This option is insecure and will allow potential Man-In-The-Middle attacks<br/>betweem OAuth2 Proxy and the usptream server.<br/>Defaults to false. |
+| `static` | _bool_ | Static will make all requests to this upstream have a static response.<br/>The response will have a body of "Authenticated" and a response code<br/>matching StaticCode.<br/>If StaticCode is not set, the response will return a 200 response. |
+| `staticCode` | _int_ | StaticCode determines the response code for the Static response.<br/>This option can only be used with Static enabled. |
+| `flushInterval` | _[Duration](#duration)_ | FlushInterval is the period between flushing the response buffer when<br/>streaming response from the upstream.<br/>Defaults to 1 second. |
+| `passHostHeader` | _bool_ | PassHostHeader determines whether the request host header should be proxied<br/>to the upstream server.<br/>Defaults to true. |
+| `proxyWebSockets` | _bool_ | ProxyWebSockets enables proxying of websockets to upstream servers<br/>Defaults to true. |

+
+:::warning
+This page contains documentation for alpha features.
+We reserve the right to make breaking changes to the features detailed within this page with no notice.
+
+Options described in this page may be changed, removed, renamed or moved without prior warning.
+Please beware of this before you use alpha configuration options.
+:::
+
+This page details a set of **alpha** configuration options in a new format.
+Going forward we are intending to add structured configuration in YAML format to
+replace the existing TOML based configuration file and flags.
+
+Below is a reference for the structure of the configuration, with
+[AlphaOptions](#alphaoptions) as the root of the configuration.
+
+When using alpha configuration, your config file will look something like below:
+
+```yaml
+upstreams:
+  - id: ...
+    ...
+injectRequestHeaders:
+  - name: ...
+    ...
+injectResponseHeaders:
+  - name: ...
+    ...
+```
+
+Please browse the [reference](#configuration-reference) below for the structure
+of the new configuration format.
+
+## Using Alpha Configuration
+
+To use the new **alpha** configuration, generate a YAML file based on the format
+described in the [reference](#configuration-reference) below.
+
+Provide the path to this file using the `--alpha-config` flag.
+
+:::note
+When using the `--alpha-config` flag, some options are no longer available.
+See [removed options](#removed-options) below for more information.
+:::
+
+### Converting configuration to the new structure
+
+Before adding the new `--alpha-config` option, start OAuth2 Proxy using the
+`convert-config-to-alpha` flag to convert existing configuration to the new format.
+
+```bash
+oauth2-proxy --convert-config-to-alpha --config ./path/to/existing/config.cfg
+```
+
+This will convert any options supported by the new format to YAML and print the
+new configuration to `STDOUT`.
+
+Copy this to a new file, remove any options from your existing configuration
+noted in [removed options](#removed-options) and then start OAuth2 Proxy using
+the new config.
+
+```bash
+oauth2-proxy --alpha-config ./path/to/new/config.yaml --config ./path/to/existing/config.cfg
+```
+
+## Removed options
+
+The following flags/options and their respective environment variables are no
+longer available when using alpha configuration:
+
+<!-- Legacy Upstream FlagSet -->
+- `flush-interval`/`flush_interval`
+- `pass-host-header`/`pass_host_header`
+- `proxy-websockets`/`proxy_websockets`
+- `ssl-upstream-insecure-skip-verify`/`ssl_upstream_insecure_skip_verify`
+- `upstream`/`upstreams`
+
+<!-- Legacy Headers FlagSet -->
+- `pass-basic-auth`/`pass_basic_auth`
+- `pass-access-token`/`pass_access_token`
+- `pass-user-headers`/`pass_user_headers`
+- `pass-authorization-header`/`pass_authorization_header`
+- `set-basic-auth`/`set_basic_auth`
+- `set-xauthrequest`/`set_xauthrequest`
+- `set-authorization-header`/`set_authorization_header`
+- `prefer-email-to-user`/`prefer_email_to_user`
+- `basic-auth-password`/`basic_auth_password`
+- `skip-auth-strip-headers`/`skip_auth_strip_headers`
+
+Attempting to use these options via flags or via config when `--alpha-config`
+set will result in an error.
+
+:::important
+You must remove these options before starting OAuth2 Proxy with `--alpha-config`

+title: OAuth Provider Configuration
+---
+
+You will need to register an OAuth application with a Provider (Google, GitHub or another provider), and configure it with Redirect URI(s) for the domain you intend to run `oauth2-proxy` on.
+
+Valid providers are :
+
+- [Google](#google-auth-provider) _default_
+- [Azure](#azure-auth-provider)
+- [Facebook](#facebook-auth-provider)
+- [GitHub](#github-auth-provider)
+- [Keycloak](#keycloak-auth-provider)
+- [GitLab](#gitlab-auth-provider)
+- [LinkedIn](#linkedin-auth-provider)
+- [Microsoft Azure AD](#microsoft-azure-ad-provider)
+- [OpenID Connect](#openid-connect-provider)
+- [login.gov](#logingov-provider)
+- [Nextcloud](#nextcloud-provider)
+- [DigitalOcean](#digitalocean-auth-provider)
+- [Bitbucket](#bitbucket-auth-provider)
+- [Gitea](#gitea-auth-provider)
+
+The provider can be selected using the `provider` configuration value.
+
+Please note that not all providers support all claims. The `preferred_username` claim is currently only supported by the OpenID Connect provider.
+
+### Google Auth Provider
+
+For Google, the registration steps are:
+
+1.  Create a new project: https://console.developers.google.com/project
+2.  Choose the new project from the top right project dropdown (only if another project is selected)
+3.  In the project Dashboard center pane, choose **"API Manager"**
+4.  In the left Nav pane, choose **"Credentials"**
+5.  In the center pane, choose **"OAuth consent screen"** tab. Fill in **"Product name shown to users"** and hit save.
+6.  In the center pane, choose **"Credentials"** tab.
+    - Open the **"New credentials"** drop down
+    - Choose **"OAuth client ID"**
+    - Choose **"Web application"**
+    - Application name is freeform, choose something appropriate
+    - Authorized JavaScript origins is your domain ex: `https://internal.yourcompany.com`
+    - Authorized redirect URIs is the location of oauth2/callback ex: `https://internal.yourcompany.com/oauth2/callback`
+    - Choose **"Create"**
+7.  Take note of the **Client ID** and **Client Secret**
+
+It's recommended to refresh sessions on a short interval (1h) with `cookie-refresh` setting which validates that the account is still authorized.
+
+#### Restrict auth to specific Google groups on your domain. (optional)
+
+1.  Create a service account: https://developers.google.com/identity/protocols/OAuth2ServiceAccount and make sure to download the json file.
+2.  Make note of the Client ID for a future step.
+3.  Under "APIs & Auth", choose APIs.
+4.  Click on Admin SDK and then Enable API.
+5.  Follow the steps on https://developers.google.com/admin-sdk/directory/v1/guides/delegation#delegate_domain-wide_authority_to_your_service_account and give the client id from step 2 the following oauth scopes:
+
+```
+https://www.googleapis.com/auth/admin.directory.group.readonly
+https://www.googleapis.com/auth/admin.directory.user.readonly
+```
+
+6.  Follow the steps on https://support.google.com/a/answer/60757 to enable Admin API access.
+7.  Create or choose an existing administrative email address on the Gmail domain to assign to the `google-admin-email` flag. This email will be impersonated by this client to make calls to the Admin SDK. See the note on the link from step 5 for the reason why.
+8.  Create or choose an existing email group and set that email to the `google-group` flag. You can pass multiple instances of this flag with different groups
+    and the user will be checked against all the provided groups.
+9.  Lock down the permissions on the json file downloaded from step 1 so only oauth2-proxy is able to read the file and set the path to the file in the `google-service-account-json` flag.
+10. Restart oauth2-proxy.
+
+Note: The user is checked against the group members list on initial authentication and every time the token is refreshed ( about once an hour ).
+
+### Azure Auth Provider
+
+1. Add an application: go to [https://portal.azure.com](https://portal.azure.com), choose **"Azure Active Directory"** in the left menu, select **"App registrations"** and then click on **"New app registration"**.
+2. Pick a name and choose **"Webapp / API"** as application type. Use `https://internal.yourcompany.com` as Sign-on URL. Click **"Create"**.
+3. On the **"Settings"** / **"Properties"** page of the app, pick a logo and select **"Multi-tenanted"** if you want to allow users from multiple organizations to access your app. Note down the application ID. Click **"Save"**.
+4. On the **"Settings"** / **"Required Permissions"** page of the app, click on **"Windows Azure Active Directory"** and then on **"Access the directory as the signed in user"**. Hit **"Save"** and then then on **"Grant permissions"** (you might need another admin to do this).
+5. On the **"Settings"** / **"Reply URLs"** page of the app, add `https://internal.yourcompanycom/oauth2/callback` for each host that you want to protect by the oauth2 proxy. Click **"Save"**.
+6. On the **"Settings"** / **"Keys"** page of the app, add a new key and note down the value after hitting **"Save"**.
+7. Configure the proxy with
+
+```
+   --provider=azure
+   --client-id=<application ID from step 3>
+   --client-secret=<value from step 6>
+```
+
+Note: When using the Azure Auth provider with nginx and the cookie session store you may find the cookie is too large and doesn't get passed through correctly. Increasing the proxy_buffer_size in nginx or implementing the [redis session storage](sessions.md#redis-storage) should resolve this.
+
+### Facebook Auth Provider
+
+1.  Create a new FB App from <https://developers.facebook.com/>
+2.  Under FB Login, set your Valid OAuth redirect URIs to `https://internal.yourcompany.com/oauth2/callback`
+
+### GitHub Auth Provider
+
+1.  Create a new project: https://github.com/settings/developers
+2.  Under `Authorization callback URL` enter the correct url ie `https://internal.yourcompany.com/oauth2/callback`
+
+The GitHub auth provider supports two additional ways to restrict authentication to either organization and optional team level access, or to collaborators of a repository. Restricting by these options is normally accompanied with `--email-domain=*`
+
+NOTE: When `--github-user` is set, the specified users are allowed to login even if they do not belong to the specified org and team or collaborators.
+
+To restrict by organization only, include the following flag:
+
+    -github-org="": restrict logins to members of this organisation
+
+To restrict within an organization to specific teams, include the following flag in addition to `-github-org`:
+
+    -github-team="": restrict logins to members of any of these teams (slug), separated by a comma
+
+If you would rather restrict access to collaborators of a repository, those users must either have push access to a public repository or any access to a private repository:
+
+    -github-repo="": restrict logins to collaborators of this repository formatted as orgname/repo
+
+If you'd like to allow access to users with **read only** access to a **public** repository you will need to provide a [token](https://github.com/settings/tokens) for a user that has write access to the repository. The token must be created with at least the `public_repo` scope:
+
+    -github-token="": the token to use when verifying repository collaborators
+
+To allow a user to login with their username even if they do not belong to the specified org and team or collaborators, separated by a comma
+
+    -github-user="": allow logins by username, separated by a comma
+
+If you are using GitHub enterprise, make sure you set the following to the appropriate url:
+
+    -login-url="http(s)://<enterprise github host>/login/oauth/authorize"
+    -redeem-url="http(s)://<enterprise github host>/login/oauth/access_token"
+    -validate-url="http(s)://<enterprise github host>/api/v3"
+
+### Keycloak Auth Provider
+
+1.  Create new client in your Keycloak with **Access Type** 'confidental' and **Valid Redirect URIs** 'https://internal.yourcompany.com/oauth2/callback'
+2.  Take note of the Secret in the credential tab of the client
+3.  Create a mapper with **Mapper Type** 'Group Membership' and **Token Claim Name** 'groups'.
+
+Make sure you set the following to the appropriate url:
+
+    --provider=keycloak
+    --client-id=<client you have created>
+    --client-secret=<your client's secret>
+    --login-url="http(s)://<keycloak host>/auth/realms/<your realm>/protocol/openid-connect/auth"
+    --redeem-url="http(s)://<keycloak host>/auth/realms/<your realm>/protocol/openid-connect/token"
+    --profile-url="http(s)://<keycloak host>/auth/realms/<your realm>/protocol/openid-connect/userinfo"
+    --validate-url="http(s)://<keycloak host>/auth/realms/<your realm>/protocol/openid-connect/userinfo"
+    --keycloak-group=<first_allowed_user_group>
+    --keycloak-group=<second_allowed_user_group>
+    
+For group based authorization, the optional `--keycloak-group` (legacy) or `--allowed-group` (global standard)
+flags can be used to specify which groups to limit access to.
+
+If these are unset but a `groups` mapper is set up above in step (3), the provider will still
+populate the `X-Forwarded-Groups` header to your upstream server with the `groups` data in the
+Keycloak userinfo endpoint response.
+
+The group management in keycloak is using a tree. If you create a group named admin in keycloak
+you should define the 'keycloak-group' value to /admin.
+
+### GitLab Auth Provider
+
+This auth provider has been tested against Gitlab version 12.X. Due to Gitlab API changes, it may not work for version prior to 12.X (see [994](https://github.com/oauth2-proxy/oauth2-proxy/issues/994)).
+
+Whether you are using GitLab.com or self-hosting GitLab, follow [these steps to add an application](https://docs.gitlab.com/ce/integration/oauth_provider.html). Make sure to enable at least the `openid`, `profile` and `email` scopes, and set the redirect url to your application url e.g. https://myapp.com/oauth2/callback.
+
+If you need projects filtering, add the extra `read_api` scope to your application.
+
+The following config should be set to ensure that the oauth will work properly. To get a cookie secret follow [these steps](./overview.md#generating-a-cookie-secret)
+
+```
+    --provider="gitlab"
+    --redirect-url="https://myapp.com/oauth2/callback" // Should be the same as the redirect url for the application in gitlab
+    --client-id=GITLAB_CLIENT_ID
+    --client-secret=GITLAB_CLIENT_SECRET
+    --cookie-secret=COOKIE_SECRET
+```
+
+Restricting by group membership is possible with the following option:
+
+    --gitlab-group="mygroup,myothergroup": restrict logins to members of any of these groups (slug), separated by a comma
+
+If you are using self-hosted GitLab, make sure you set the following to the appropriate URL:
+
+    --oidc-issuer-url="<your gitlab url>"
+
+### LinkedIn Auth Provider
+
+For LinkedIn, the registration steps are:
+
+1.  Create a new project: https://www.linkedin.com/secure/developer
+2.  In the OAuth User Agreement section:
+    - In default scope, select r_basicprofile and r_emailaddress.
+    - In "OAuth 2.0 Redirect URLs", enter `https://internal.yourcompany.com/oauth2/callback`
+3.  Fill in the remaining required fields and Save.
+4.  Take note of the **Consumer Key / API Key** and **Consumer Secret / Secret Key**
+
+### Microsoft Azure AD Provider
+
+For adding an application to the Microsoft Azure AD follow [these steps to add an application](https://docs.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-app).
+
+Take note of your `TenantId` if applicable for your situation. The `TenantId` can be used to override the default `common` authorization server with a tenant specific server.
+
+### OpenID Connect Provider
+
+OpenID Connect is a spec for OAUTH 2.0 + identity that is implemented by many major providers and several open source projects.
+
+This provider was originally built against CoreOS Dex and we will use it as an example.
+The OpenID Connect Provider (OIDC) can also be used to connect to other Identity Providers such as Okta, an example can be found below.
+
+#### Dex
+
+To configure the OIDC provider for Dex, perform the following steps:
+
+1. Download Dex:
+
+    ```
+    go get github.com/dexidp/dex
+    ```
+
+    See the [getting started guide](https://github.com/coreos/dex/blob/master/Documentation/getting-started.md) for more details.
+
+2. Setup oauth2-proxy with the correct provider and using the default ports and callbacks. Add a configuration block to the `staticClients` section of `examples/config-dev.yaml`:
+
+    ```
+    - id: oauth2-proxy
+    redirectURIs:
+    - 'http://127.0.0.1:4180/oauth2/callback'
+    name: 'oauth2-proxy'
+    secret: proxy
+    ```
+
+3. Launch Dex: from `$GOPATH/github.com/dexidp/dex`, run:
+
+    ```
+    bin/dex serve examples/config-dev.yaml
+    ```
+
+4. In a second terminal, run the oauth2-proxy with the following args:
+
+    ```
+    -provider oidc
+    -provider-display-name "My OIDC Provider"
+    -client-id oauth2-proxy
+    -client-secret proxy
+    -redirect-url http://127.0.0.1:4180/oauth2/callback
+    -oidc-issuer-url http://127.0.0.1:5556/dex
+    -cookie-secure=false
+    -cookie-secret=secret
+    -email-domain kilgore.trout
+    ```
+
+    To serve the current working directory as a web site under the `/static` endpoint, add:
+
+    ```
+    -upstream file://$PWD/#/static/
+    ```
+
+5. Test the setup by visiting http://127.0.0.1:4180 or http://127.0.0.1:4180/static .
+
+See also [our local testing environment](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/contrib/local-environment) for a self-contained example using Docker and etcd as storage for Dex.
+
+#### Okta
+
+To configure the OIDC provider for Okta, perform the following steps:
+
+1. Log in to Okta using an administrative account. It is suggested you try this in preview first, `example.oktapreview.com`
+2. (OPTIONAL) If you want to configure authorization scopes and claims to be passed on to multiple applications,
+you may wish to configure an authorization server for each application. Otherwise, the provided `default` will work.
+* Navigate to **Security** then select **API**
+* Click **Add Authorization Server**, if this option is not available you may require an additional license for a custom authorization server.
+* Fill out the **Name** with something to describe the application you are protecting. e.g. 'Example App'.
+* For **Audience**, pick the URL of the application you wish to protect: https://example.corp.com
+* Fill out a **Description**
+* Add any **Access Policies** you wish to configure to limit application access.
+* The default settings will work for other options.
+[See Okta documentation for more information on Authorization Servers](https://developer.okta.com/docs/guides/customize-authz-server/overview/)
+3. Navigate to **Applications** then select **Add Application**.
+* Select **Web** for the **Platform** setting.
+* Select **OpenID Connect** and click **Create**
+* Pick an **Application Name** such as `Example App`.
+* Set the **Login redirect URI** to `https://example.corp.com`.
+* Under **General** set the **Allowed grant types** to `Authorization Code` and `Refresh Token`.
+* Leave the rest as default, taking note of the `Client ID` and `Client Secret`.
+* Under **Assignments** select the users or groups you wish to access your application.
+4. Create a configuration file like the following:
+
+    ```
+    provider = "oidc"
+    redirect_url = "https://example.corp.com/oauth2/callback"
+    oidc_issuer_url = "https://corp.okta.com/oauth2/abCd1234"
+    upstreams = [
+        "https://example.corp.com"
+    ]
+    email_domains = [
+        "corp.com"
+    ]
+    client_id = "XXXXX"
+    client_secret = "YYYYY"
+    pass_access_token = true
+    cookie_secret = "ZZZZZ"
+    skip_provider_button = true
+    ```
+
+The `oidc_issuer_url` is based on URL from your **Authorization Server**'s **Issuer** field in step 2, or simply https://corp.okta.com .
+The `client_id` and `client_secret` are configured in the application settings.
+Generate a unique `client_secret` to encrypt the cookie.
+
+Then you can start the oauth2-proxy with `./oauth2-proxy --config /etc/example.cfg`
+
+#### Okta - localhost
+
+1. Signup for developer account: https://developer.okta.com/signup/
+2. Create New `Web` Application: https://${your-okta-domain}/dev/console/apps/new
+3. Example Application Settings for localhost:
+   * **Name:** My Web App
+   * **Base URIs:** http://localhost:4180/
+   * **Login redirect URIs:** http://localhost:4180/oauth2/callback
+   * **Logout redirect URIs:** http://localhost:4180/
+   * **Group assignments:** `Everyone`
+   * **Grant type allowed:** `Authorization Code` and `Refresh Token`
+4. Make note of the `Client ID` and `Client secret`, they are needed in a future step
+5. Make note of the **default** Authorization Server Issuer URI from: https://${your-okta-domain}/admin/oauth2/as
+6. Example config file `/etc/localhost.cfg`
+    ```
+    provider = "oidc"
+    redirect_url = "http://localhost:4180/oauth2/callback"
+    oidc_issuer_url = "https://${your-okta-domain}/oauth2/default"
+    upstreams = [
+        "http://0.0.0.0:8080"
+    ]
+    email_domains = [
+        "*"
+    ]
+    client_id = "XXX"
+    client_secret = "YYY"
+    pass_access_token = true
+    cookie_secret = "ZZZ"
+    cookie_secure = false
+    skip_provider_button = true
+    # Note: use the following for testing within a container
+    # http_address = "0.0.0.0:4180"
+    ```
+7. Then you can start the oauth2-proxy with `./oauth2-proxy --config /etc/localhost.cfg`
+
+### login.gov Provider
+
+login.gov is an OIDC provider for the US Government.
+If you are a US Government agency, you can contact the login.gov team through the contact information
+that you can find on https://login.gov/developers/ and work with them to understand how to get login.gov
+accounts for integration/test and production access.
+
+A developer guide is available here: https://developers.login.gov/, though this proxy handles everything
+but the data you need to create to register your application in the login.gov dashboard.
+
+As a demo, we will assume that you are running your application that you want to secure locally on
+http://localhost:3000/, that you will be starting your proxy up on http://localhost:4180/, and that
+you have an agency integration account for testing.
+
+First, register your application in the dashboard.  The important bits are:
+  * Identity protocol:  make this `Openid connect`
+  * Issuer:  do what they say for OpenID Connect.  We will refer to this string as `${LOGINGOV_ISSUER}`.
+  * Public key:  This is a self-signed certificate in .pem format generated from a 2048 bit RSA private key.
+    A quick way to do this is `openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 3650 -nodes -subj '/C=US/ST=Washington/L=DC/O=GSA/OU=18F/CN=localhost'`,
+    The contents of the `key.pem` shall be referred to as `${OAUTH2_PROXY_JWT_KEY}`.
+  * Return to App URL:  Make this be `http://localhost:4180/`
+  * Redirect URIs:  Make this be `http://localhost:4180/oauth2/callback`.
+  * Attribute Bundle:  Make sure that email is selected.
+
+Now start the proxy up with the following options:
+```
+./oauth2-proxy -provider login.gov \
+  -client-id=${LOGINGOV_ISSUER} \
+  -redirect-url=http://localhost:4180/oauth2/callback \
+  -oidc-issuer-url=https://idp.int.identitysandbox.gov/ \
+  -cookie-secure=false \
+  -email-domain=gsa.gov \
+  -upstream=http://localhost:3000/ \
+  -cookie-secret=somerandomstring12341234567890AB \
+  -cookie-domain=localhost \
+  -skip-provider-button=true \
+  -pubjwk-url=https://idp.int.identitysandbox.gov/api/openid_connect/certs \
+  -profile-url=https://idp.int.identitysandbox.gov/api/openid_connect/userinfo \
+  -jwt-key="${OAUTH2_PROXY_JWT_KEY}"
+```
+You can also set all these options with environment variables, for use in cloud/docker environments.
+One tricky thing that you may encounter is that some cloud environments will pass in environment
+variables in a docker env-file, which does not allow multiline variables like a PEM file.
+If you encounter this, then you can create a `jwt_signing_key.pem` file in the top level
+directory of the repo which contains the key in PEM format and then do your docker build.
+The docker build process will copy that file into your image which you can then access by
+setting the `OAUTH2_PROXY_JWT_KEY_FILE=/etc/ssl/private/jwt_signing_key.pem`
+environment variable, or by setting `--jwt-key-file=/etc/ssl/private/jwt_signing_key.pem` on the commandline.
+
+Once it is running, you should be able to go to `http://localhost:4180/` in your browser,
+get authenticated by the login.gov integration server, and then get proxied on to your
+application running on `http://localhost:3000/`.  In a real deployment, you would secure
+your application with a firewall or something so that it was only accessible from the
+proxy, and you would use real hostnames everywhere.
+
+#### Skip OIDC discovery
+
+Some providers do not support OIDC discovery via their issuer URL, so oauth2-proxy cannot simply grab the authorization, token and jwks URI endpoints from the provider's metadata.
+
+In this case, you can set the `--skip-oidc-discovery` option, and supply those required endpoints manually:
+
+```
+    -provider oidc
+    -client-id oauth2-proxy
+    -client-secret proxy
+    -redirect-url http://127.0.0.1:4180/oauth2/callback
+    -oidc-issuer-url http://127.0.0.1:5556
+    -skip-oidc-discovery
+    -login-url http://127.0.0.1:5556/authorize
+    -redeem-url http://127.0.0.1:5556/token
+    -oidc-jwks-url http://127.0.0.1:5556/keys
+    -cookie-secure=false
+    -email-domain example.com
+```
+
+### Nextcloud Provider
+
+The Nextcloud provider allows you to authenticate against users in your
+Nextcloud instance.
+
+When you are using the Nextcloud provider, you must specify the urls via
+configuration, environment variable, or command line argument. Depending
+on whether your Nextcloud instance is using pretty urls your urls may be of the
+form `/index.php/apps/oauth2/*` or `/apps/oauth2/*`.
+
+Refer to the [OAuth2
+documentation](https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/oauth2.html)
+to setup the client id and client secret. Your "Redirection URI" will be
+`https://internalapp.yourcompany.com/oauth2/callback`.
+
+```
+    -provider nextcloud
+    -client-id <from nextcloud admin>
+    -client-secret <from nextcloud admin>
+    -login-url="<your nextcloud url>/index.php/apps/oauth2/authorize"
+    -redeem-url="<your nextcloud url>/index.php/apps/oauth2/api/v1/token"
+    -validate-url="<your nextcloud url>/ocs/v2.php/cloud/user?format=json"
+```
+
+Note: in *all* cases the validate-url will *not* have the `index.php`.
+
+### DigitalOcean Auth Provider
+
+1. [Create a new OAuth application](https://cloud.digitalocean.com/account/api/applications)
+    * You can fill in the name, homepage, and description however you wish.
+    * In the "Application callback URL" field, enter: `https://oauth-proxy/oauth2/callback`, substituting `oauth2-proxy` with the actual hostname that oauth2-proxy is running on. The URL must match oauth2-proxy's configured redirect URL.
+2. Note the Client ID and Client Secret.
+
+To use the provider, pass the following options:
+
+```
+   --provider=digitalocean
+   --client-id=<Client ID>
+   --client-secret=<Client Secret>
+```
+
+ Alternatively, set the equivalent options in the config file. The redirect URL defaults to `https://<requested host header>/oauth2/callback`. If you need to change it, you can use the `--redirect-url` command-line option.
+
+### Bitbucket Auth Provider
+
+1. [Add a new OAuth consumer](https://confluence.atlassian.com/bitbucket/oauth-on-bitbucket-cloud-238027431.html)
+    * In "Callback URL" use `https://<oauth2-proxy>/oauth2/callback`, substituting `<oauth2-proxy>` with the actual hostname that oauth2-proxy is running on.
+    * In Permissions section select:
+        * Account -> Email
+        * Team membership -> Read
+        * Repositories -> Read
+2. Note the Client ID and Client Secret.
+
+To use the provider, pass the following options:
+
+```
+   --provider=bitbucket
+   --client-id=<Client ID>
+   --client-secret=<Client Secret>
+```
+
+The default configuration allows everyone with Bitbucket account to authenticate. To restrict the access to the team members use additional configuration option: `--bitbucket-team=<Team name>`. To restrict the access to only these users who has access to one selected repository use `--bitbucket-repository=<Repository name>`.
+
+
+### Gitea Auth Provider
+
+1. Create a new application: `https://< your gitea host >/user/settings/applications`
+2. Under `Redirect URI` enter the correct URL i.e. `https://<proxied host>/oauth2/callback`
+3. Note the Client ID and Client Secret.
+4. Pass the following options to the proxy:
+
+```
+    --provider="github"
+    --redirect-url="https://<proxied host>/oauth2/callback"
+    --provider-display-name="Gitea"
+    --client-id="< client_id as generated by Gitea >"
+    --client-secret="< client_secret as generated by Gitea >"
+    --login-url="https://< your gitea host >/login/oauth/authorize"
+    --redeem-url="https://< your gitea host >/login/oauth/access_token"
+    --validate-url="https://< your gitea host >/api/v1"
+```
+
+
+## Email Authentication
+
+To authorize by email domain use `--email-domain=yourcompany.com`. To authorize individual email addresses use `--authenticated-emails-file=/path/to/file` with one email per line. To authorize all email addresses use `--email-domain=*`.
+
+## Adding a new Provider
+
+Follow the examples in the [`providers` package](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/providers/) to define a new
+`Provider` instance. Add a new `case` to
+[`providers.New()`](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/providers/providers.go) to allow `oauth2-proxy` to use the
+new `Provider`.

+
+`oauth2-proxy` can be configured via [config file](#config-file), [command line options](#command-line-options) or [environment variables](#environment-variables).
+
+### Generating a Cookie Secret
+
+To generate a strong cookie secret use `python -c 'import os,base64; print(base64.urlsafe_b64encode(os.urandom(16)).decode())'`
+
+### Config File
+
+Every command line argument can be specified in a config file by replacing hyphens (-) with underscores (\_). If the argument can be specified multiple times, the config option should be plural (trailing s).
+
+An example [oauth2-proxy.cfg](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/contrib/oauth2-proxy.cfg.example) config file is in the contrib directory. It can be used by specifying `--config=/etc/oauth2-proxy.cfg`

When combined with `--reverse-proxy` and optionally `--real-client-ip-header` this will evaluate the trust of the IP stored in an HTTP header by a reverse proxy rather than the layer-3/4 remote address. WARNING: trusting IPs has inherent security flaws, especially when obtaining the IP address from an HTTP header (reverse-proxy mode). Use this option only if you understand the risks and how to manage them. | |
+
+\[<a name="footnote1">1</a>\]: Only these providers support `--cookie-refresh`: GitLab, Google and OIDC
+
+\[<a name="footnote2">2</a>\]: When using the `whitelist-domain` option, any domain prefixed with a `.` will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: `example.com:8080`. To allow any port, use `*`: `example.com:*`.
+
+See below for provider specific options
+
+### Upstreams Configuration
+
+`oauth2-proxy` supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as `http://127.0.0.1:8080/` for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide `http://127.0.0.1:8080/some/path/` then it will only be requests that start with `/some/path/` which are forwarded to the upstream.
+
+Static file paths are configured as a file:// URL. `file:///var/www/static/` will serve the files from that directory at `http://[oauth2-proxy url]/var/www/static/`, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. `file:///var/www/static/#/static/` will make `/var/www/static/` available at `http://[oauth2-proxy url]/static/`.
+
+Multiple upstreams can either be configured by supplying a comma separated list to the `--upstream` parameter, supplying the parameter multiple times or providing a list in the [config file](#config-file). When multiple upstreams are used routing to them will be based on the path they are set up with.
+
+### Environment variables
+
+Every command line argument can be specified as an environment variable by
+prefixing it with `OAUTH2_PROXY_`, capitalising it, and replacing hyphens (`-`)
+with underscores (`_`). If the argument can be specified multiple times, the
+environment variable should be plural (trailing `S`).
+
+This is particularly useful for storing secrets outside of a configuration file
+or the command line.
+
+For example, the `--cookie-secret` flag becomes `OAUTH2_PROXY_COOKIE_SECRET`,
+and the `--email-domain` flag becomes `OAUTH2_PROXY_EMAIL_DOMAINS`.
+
+## Logging Configuration
+
+By default, OAuth2 Proxy logs all output to stdout. Logging can be configured to output to a rotating log file using the `--logging-filename` command.
+
+If logging to a file you can also configure the maximum file size (`--logging-max-size`), age (`--logging-max-age`), max backup logs (`--logging-max-backups`), and if backup logs should be compressed (`--logging-compress`).
+
+There are three different types of logging: standard, authentication, and HTTP requests. These can each be enabled or disabled with `--standard-logging`, `--auth-logging`, and `--request-logging`.
+
+Each type of logging has its own configurable format and variables. By default these formats are similar to the Apache Combined Log.
+
+Logging of requests to the `/ping` endpoint (or using `--ping-user-agent`) can be disabled with `--silence-ping-logging` reducing log volume. This flag appends the `--ping-path` to `--exclude-logging-paths`.
+
+### Auth Log Format
+Authentication logs are logs which are guaranteed to contain a username or email address of a user attempting to authenticate. These logs are output by default in the below format:
+
+```
+<REMOTE_ADDRESS> - <user@domain.com> [19/Mar/2015:17:20:19 -0400] [<STATUS>] <MESSAGE>
+```
+
+The status block will contain one of the below strings:
+
+- `AuthSuccess` If a user has authenticated successfully by any method
+- `AuthFailure` If the user failed to authenticate explicitly
+- `AuthError` If there was an unexpected error during authentication
+
+If you require a different format than that, you can configure it with the `--auth-logging-format` flag.
+The default format is configured as follows:
+
+```
+{{.Client}} - {{.Username}} [{{.Timestamp}}] [{{.Status}}] {{.Message}}
+```
+
+Available variables for auth logging:
+
+| Variable | Example | Description |

+
+## Configuring for use with the Nginx `auth_request` directive
+
+The [Nginx `auth_request` directive](http://nginx.org/en/docs/http/ngx_http_auth_request_module.html) allows Nginx to authenticate requests via the oauth2-proxy's `/auth` endpoint, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the request through. For example:
+
+```nginx
+server {
+  listen 443 ssl;
+  server_name ...;
+  include ssl/ssl.conf;
+
+  location /oauth2/ {
+    proxy_pass       http://127.0.0.1:4180;
+    proxy_set_header Host                    $host;

+    proxy_set_header X-Scheme                $scheme;
+    proxy_set_header X-Auth-Request-Redirect $request_uri;
+    # or, if you are handling multiple domains:
+    # proxy_set_header X-Auth-Request-Redirect $scheme://$host$request_uri;
+  }
+  location = /oauth2/auth {
+    proxy_pass       http://127.0.0.1:4180;
+    proxy_set_header Host             $host;
+    proxy_set_header X-Real-IP        $remote_addr;
+    proxy_set_header X-Scheme         $scheme;
+    # nginx auth_request includes headers but not body
+    proxy_set_header Content-Length   "";
+    proxy_pass_request_body           off;
+  }
+
+  location / {
+    auth_request /oauth2/auth;
+    error_page 401 = /oauth2/sign_in;
+
+    # pass information via X-User and X-Email headers to backend,
+    # requires running with --set-xauthrequest flag
+    auth_request_set $user   $upstream_http_x_auth_request_user;
+    auth_request_set $email  $upstream_http_x_auth_request_email;
+    proxy_set_header X-User  $user;
+    proxy_set_header X-Email $email;
+
+    # if you enabled --pass-access-token, this will pass the token to the backend
+    auth_request_set $token  $upstream_http_x_auth_request_access_token;
+    proxy_set_header X-Access-Token $token;
+
+    # if you enabled --cookie-refresh, this is needed for it to work with auth_request
+    auth_request_set $auth_cookie $upstream_http_set_cookie;
+    add_header Set-Cookie $auth_cookie;
+
+    # When using the --set-authorization-header flag, some provider's cookies can exceed the 4kb
+    # limit and so the OAuth2 Proxy splits these into multiple parts.
+    # Nginx normally only copies the first `Set-Cookie` header from the auth_request to the response,
+    # so if your cookies are larger than 4kb, you will need to extract additional cookies manually.
+    auth_request_set $auth_cookie_name_upstream_1 $upstream_cookie_auth_cookie_name_1;
+
+    # Extract the Cookie attributes from the first Set-Cookie header and append them
+    # to the second part ($upstream_cookie_* variables only contain the raw cookie content)
+    if ($auth_cookie ~* "(; .*)") {
+        set $auth_cookie_name_0 $auth_cookie;
+        set $auth_cookie_name_1 "auth_cookie_name_1=$auth_cookie_name_upstream_1$1";
+    }
+
+    # Send both Set-Cookie headers now if there was a second part
+    if ($auth_cookie_name_upstream_1) {
+        add_header Set-Cookie $auth_cookie_name_0;
+        add_header Set-Cookie $auth_cookie_name_1;
+    }
+
+    proxy_pass http://backend/;
+    # or "root /path/to/site;" or "fastcgi_pass ..." etc
+  }
+}
+```
+
+When you use ingress-nginx in Kubernetes, you MUST use `kubernetes/ingress-nginx` (which includes the Lua module) and the following configuration snippet for your `Ingress`.
+Variables set with `auth_request_set` are not `set`-able in plain nginx config when the location is processed via `proxy_pass` and then may only be processed by Lua.
+Note that `nginxinc/kubernetes-ingress` does not include the Lua module.
+
+```yaml
+nginx.ingress.kubernetes.io/auth-response-headers: Authorization
+nginx.ingress.kubernetes.io/auth-signin: https://$host/oauth2/start?rd=$escaped_request_uri
+nginx.ingress.kubernetes.io/auth-url: https://$host/oauth2/auth
+nginx.ingress.kubernetes.io/configuration-snippet: |
+  auth_request_set $name_upstream_1 $upstream_cookie_name_1;
+
+  access_by_lua_block {
+    if ngx.var.name_upstream_1 ~= "" then
+      ngx.header["Set-Cookie"] = "name_1=" .. ngx.var.name_upstream_1 .. ngx.var.auth_cookie:match("(; .*)")
+    end
+  }
+```
+It is recommended to use `--session-store-type=redis` when expecting large sessions/OIDC tokens (_e.g._ with MS Azure).
+
+You have to substitute *name* with the actual cookie name you configured via --cookie-name parameter. If you don't set a custom cookie name the variable  should be "$upstream_cookie__oauth2_proxy_1" instead of "$upstream_cookie_name_1" and the new cookie-name should be "_oauth2_proxy_1=" instead of "name_1=".

+## Configuring for use with the Traefik (v2) `ForwardAuth` middleware

+**This option requires `--reverse-proxy` option to be set.**
+
+### ForwardAuth with 401 errors middleware
+
+The [Traefik v2 `ForwardAuth` middleware](https://doc.traefik.io/traefik/middlewares/forwardauth/) allows Traefik to authenticate requests via the oauth2-proxy's `/oauth2/auth` endpoint on every request, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the whole request through. For example, on Dynamic File (YAML) Configuration:
+
+```yaml

+id: session_storage
+title: Session Storage
+---
+
+Sessions allow a user's authentication to be tracked between multiple HTTP
+requests to a service.
+
+The OAuth2 Proxy uses a Cookie to track user sessions and will store the session
+data in one of the available session storage backends.
+
+At present the available backends are (as passed to `--session-store-type`):
+- [cookie](#cookie-storage) (default)
+- [redis](#redis-storage)
+
+### Cookie Storage
+
+The Cookie storage backend is the default backend implementation and has
+been used in the OAuth2 Proxy historically.
+
+With the Cookie storage backend, all session information is stored in client
+side cookies and transferred with each and every request.
+
+The following should be known when using this implementation:
+- Since all state is stored client side, this storage backend means that the OAuth2 Proxy is completely stateless
+- Cookies are signed server side to prevent modification client-side
+- It is mandatory to set a `cookie-secret` which will ensure data is encrypted within the cookie data.
+- Since multiple requests can be made concurrently to the OAuth2 Proxy, this session implementation
+cannot lock sessions and while updating and refreshing sessions, there can be conflicts which force
+users to re-authenticate
+
+
+### Redis Storage
+
+The Redis Storage backend stores sessions, encrypted, in redis. Instead sending all the information
+back the the client for storage, as in the [Cookie storage](#cookie-storage), a ticket is sent back
+to the user as the cookie value instead.
+
+A ticket is composed as the following:
+
+`{CookieName}-{ticketID}.{secret}`
+
+Where:
+
+- The `CookieName` is the OAuth2 cookie name (_oauth2_proxy by default)
+- The `ticketID` is a 128 bit random number, hex-encoded
+- The `secret` is a 128 bit random number, base64url encoded (no padding). The secret is unique for every session.
+- The pair of `{CookieName}-{ticketID}` comprises a ticket handle, and thus, the redis key
+to which the session is stored. The encoded session is encrypted with the secret and stored
+in redis via the `SETEX` command.
+
+Encrypting every session uniquely protects the refresh/access/id tokens stored in the session from
+disclosure.
+
+#### Usage
+
+When using the redis store, specify `--session-store-type=redis` as well as the Redis connection URL, via
+`--redis-connection-url=redis://host[:port][/db-number]`.
+
+You may also configure the store for Redis Sentinel. In this case, you will want to use the
+`--redis-use-sentinel=true` flag, as well as configure the flags `--redis-sentinel-master-name`
+and `--redis-sentinel-connection-urls` appropriately.
+
+Redis Cluster is available to be the backend store as well. To leverage it, you will need to set the
+`--redis-use-cluster=true` flag, and configure the flags `--redis-cluster-connection-urls` appropriately.
+
+Note that flags `--redis-use-sentinel=true` and `--redis-use-cluster=true` are mutually exclusive.

+
+There are two recommended configurations.
+
+1.  Configure SSL Termination with OAuth2 Proxy by providing a `--tls-cert-file=/path/to/cert.pem` and `--tls-key-file=/path/to/cert.key`.
+
+    The command line to run `oauth2-proxy` in this configuration would look like this:
+
+    ```bash
+    ./oauth2-proxy \
+        --email-domain="yourcompany.com"  \
+        --upstream=http://127.0.0.1:8080/ \
+        --tls-cert-file=/path/to/cert.pem \
+        --tls-key-file=/path/to/cert.key \
+        --cookie-secret=... \
+        --cookie-secure=true \
+        --provider=... \
+        --client-id=... \
+        --client-secret=...
+    ```
+
+2.  Configure SSL Termination with [Nginx](http://nginx.org/) (example config below), Amazon ELB, Google Cloud Platform Load Balancing, or ....
+
+    Because `oauth2-proxy` listens on `127.0.0.1:4180` by default, to listen on all interfaces (needed when using an
+    external load balancer like Amazon ELB or Google Platform Load Balancing) use `--http-address="0.0.0.0:4180"` or
+    `--http-address="http://:4180"`.
+
+    Nginx will listen on port `443` and handle SSL connections while proxying to `oauth2-proxy` on port `4180`.
+    `oauth2-proxy` will then authenticate requests for an upstream application. The external endpoint for this example
+    would be `https://internal.yourcompany.com/`.
+
+    An example Nginx config follows. Note the use of `Strict-Transport-Security` header to pin requests to SSL
+    via [HSTS](http://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security):
+
+    ```
+    server {
+        listen 443 default ssl;
+        server_name internal.yourcompany.com;
+        ssl_certificate /path/to/cert.pem;
+        ssl_certificate_key /path/to/cert.key;
+        add_header Strict-Transport-Security max-age=2592000;
+
+        location / {
+            proxy_pass http://127.0.0.1:4180;
+            proxy_set_header Host $host;
+            proxy_set_header X-Real-IP $remote_addr;
+            proxy_set_header X-Scheme $scheme;
+            proxy_connect_timeout 1;
+            proxy_send_timeout 30;
+            proxy_read_timeout 30;
+        }
+    }
+    ```
+
+    The command line to run `oauth2-proxy` in this configuration would look like this:
+
+    ```bash
+    ./oauth2-proxy \
+       --email-domain="yourcompany.com"  \
+       --upstream=http://127.0.0.1:8080/ \
+       --cookie-secret=... \

+
+OAuth2 Proxy responds directly to the following endpoints. All other endpoints will be proxied upstream when authenticated. The `/oauth2` prefix can be changed with the `--proxy-prefix` config variable.
+
+- /robots.txt - returns a 200 OK response that disallows all User-agents from all paths; see [robotstxt.org](http://www.robotstxt.org/) for more info
+- /ping - returns a 200 OK response, which is intended for use with health checks
+- /oauth2/sign_in - the login page, which also doubles as a sign out page (it clears cookies)
+- /oauth2/sign_out - this URL is used to clear the session cookie
+- /oauth2/start - a URL that will redirect to start the OAuth cycle
+- /oauth2/callback - the URL used at the end of the OAuth cycle. The oauth app will be configured with this as the callback url.
+- /oauth2/userinfo - the URL is used to return user's email from the session in JSON format.
+- /oauth2/auth - only returns a 202 Accepted response or a 401 Unauthorized response; for use with the [Nginx `auth_request` directive](../configuration/overview.md#configuring-for-use-with-the-nginx-auth_request-directive)
+
+### Sign out
+
+To sign the user out, redirect them to `/oauth2/sign_out`. This endpoint only removes oauth2-proxy's own cookies, i.e. the user is still logged in with the authentication provider and may automatically re-login when accessing the application again. You will also need to redirect the user to the authentication provider's sign out page afterwards using the `rd` query parameter, i.e. redirect the user to something like (notice the url-encoding!):
+
+```
+/oauth2/sign_out?rd=https%3A%2F%2Fmy-oidc-provider.example.com%2Fsign_out_page
+```
+
+Alternatively, include the redirect URL in the `X-Auth-Request-Redirect` header:
+
+```
+GET /oauth2/sign_out HTTP/1.1
+X-Auth-Request-Redirect: https://my-oidc-provider/sign_out_page
+...
+```
+
+(The "sign_out_page" should be the [`end_session_endpoint`](https://openid.net/specs/openid-connect-session-1_0.html#rfc.section.2.1) from [the metadata](https://openid.net/specs/openid-connect-discovery-1_0.html#ProviderConfig) if your OIDC provider supports Session Management and Discovery.)
+
+BEWARE that the domain you want to redirect to (`my-oidc-provider.example.com` in the example) must be added to the [`--whitelist-domain`](../configuration/overview) configuration option otherwise the redirect will be ignored.

+2. If authentication is required but missing then the user is asked to log in and redirected to the authentication provider (unless it is an Ajax request, i.e. one with `Accept: application/json`, in which case 401 Unauthorized is returned)
+3. After returning from the authentication provider, the oauth tokens are stored in the configured session store (cookie, redis, ...) and a cookie is set

+OAuth2 Proxy is a community project.
+Maintainers do not work on this project full time, and as such,
+while we endeavour to respond to disclosures as quickly as possible,
+this may take longer than in projects with corporate sponsorship.
+:::
+
+## Security Disclosures
+
+:::important
+If you believe you have found a vulnerability within OAuth2 Proxy or any of its
+dependencies, please do NOT open an issue or PR on GitHub, please do NOT post
+any details publicly.
+:::
+
+Security disclosures MUST be done in private.
+If you have found an issue that you would like to bring to the attention of the
+maintenance team for OAuth2 Proxy, please compose an email and send it to the
+list of maintainers in our [MAINTAINERS](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/MAINTAINERS) file.
+
+Please include as much detail as possible.
+Ideally, your disclosure should include:
+- A reproducible case that can be used to demonstrate the exploit
+- How you discovered this vulnerability
+- A potential fix for the issue (if you have thought of one)
+- Versions affected (if not present in master)
+- Your GitHub ID
+
+### How will we respond to disclosures?
+
+We use [GitHub Security Advisories](https://docs.github.com/en/github/managing-security-vulnerabilities/about-github-security-advisories)
+to privately discuss fixes for disclosed vulnerabilities.
+If you include a GitHub ID with your disclosure we will add you as a collaborator
+for the advisory so that you can join the discussion and validate any fixes
+we may propose.
+
+For minor issues and previously disclosed vulnerabilities (typically for
+dependencies), we may use regular PRs for fixes and forego the security advisory.
+
+Once a fix has been agreed upon, we will merge the fix and create a new release.
+If we have multiple security issues in flight simultaneously, we may delay
+merging fixes until all patches are ready.
+We may also backport the fix to previous releases,
+but this will be at the discretion of the maintainers.

+
+You will need to register an OAuth application with a Provider (Google, GitHub or another provider), and configure it with Redirect URI(s) for the domain you intend to run `oauth2-proxy` on.
+
+Valid providers are :
+
+- [Google](#google-auth-provider) _default_
+- [Azure](#azure-auth-provider)
+- [Facebook](#facebook-auth-provider)
+- [GitHub](#github-auth-provider)
+- [Keycloak](#keycloak-auth-provider)

+- [Nextcloud](#nextcloud-provider)
+- [DigitalOcean](#digitalocean-auth-provider)
+- [Bitbucket](#bitbucket-auth-provider)
+- [Gitea](#gitea-auth-provider)
+
+The provider can be selected using the `provider` configuration value.
+
+Please note that not all providers support all claims. The `preferred_username` claim is currently only supported by the OpenID Connect provider.
+
+### Google Auth Provider
+
+For Google, the registration steps are:
+
+1.  Create a new project: https://console.developers.google.com/project
+2.  Choose the new project from the top right project dropdown (only if another project is selected)
+3.  In the project Dashboard center pane, choose **"API Manager"**
+4.  In the left Nav pane, choose **"Credentials"**
+5.  In the center pane, choose **"OAuth consent screen"** tab. Fill in **"Product name shown to users"** and hit save.
+6.  In the center pane, choose **"Credentials"** tab.
+    - Open the **"New credentials"** drop down
+    - Choose **"OAuth client ID"**
+    - Choose **"Web application"**
+    - Application name is freeform, choose something appropriate
+    - Authorized JavaScript origins is your domain ex: `https://internal.yourcompany.com`
+    - Authorized redirect URIs is the location of oauth2/callback ex: `https://internal.yourcompany.com/oauth2/callback`
+    - Choose **"Create"**
+7.  Take note of the **Client ID** and **Client Secret**
+
+It's recommended to refresh sessions on a short interval (1h) with `cookie-refresh` setting which validates that the account is still authorized.
+
+#### Restrict auth to specific Google groups on your domain. (optional)
+
+1.  Create a service account: https://developers.google.com/identity/protocols/OAuth2ServiceAccount and make sure to download the json file.
+2.  Make note of the Client ID for a future step.
+3.  Under "APIs & Auth", choose APIs.
+4.  Click on Admin SDK and then Enable API.
+5.  Follow the steps on https://developers.google.com/admin-sdk/directory/v1/guides/delegation#delegate_domain-wide_authority_to_your_service_account and give the client id from step 2 the following oauth scopes:
+
+```
+https://www.googleapis.com/auth/admin.directory.group.readonly
+https://www.googleapis.com/auth/admin.directory.user.readonly
+```
+
+6.  Follow the steps on https://support.google.com/a/answer/60757 to enable Admin API access.
+7.  Create or choose an existing administrative email address on the Gmail domain to assign to the `google-admin-email` flag. This email will be impersonated by this client to make calls to the Admin SDK. See the note on the link from step 5 for the reason why.
+8.  Create or choose an existing email group and set that email to the `google-group` flag. You can pass multiple instances of this flag with different groups
+    and the user will be checked against all the provided groups.
+9.  Lock down the permissions on the json file downloaded from step 1 so only oauth2-proxy is able to read the file and set the path to the file in the `google-service-account-json` flag.
+10. Restart oauth2-proxy.
+
+Note: The user is checked against the group members list on initial authentication and every time the token is refreshed ( about once an hour ).
+
+### Azure Auth Provider
+
+1. Add an application: go to [https://portal.azure.com](https://portal.azure.com), choose **"Azure Active Directory"** in the left menu, select **"App registrations"** and then click on **"New app registration"**.
+2. Pick a name and choose **"Webapp / API"** as application type. Use `https://internal.yourcompany.com` as Sign-on URL. Click **"Create"**.
+3. On the **"Settings"** / **"Properties"** page of the app, pick a logo and select **"Multi-tenanted"** if you want to allow users from multiple organizations to access your app. Note down the application ID. Click **"Save"**.
+4. On the **"Settings"** / **"Required Permissions"** page of the app, click on **"Windows Azure Active Directory"** and then on **"Access the directory as the signed in user"**. Hit **"Save"** and then then on **"Grant permissions"** (you might need another admin to do this).
+5. On the **"Settings"** / **"Reply URLs"** page of the app, add `https://internal.yourcompanycom/oauth2/callback` for each host that you want to protect by the oauth2 proxy. Click **"Save"**.
+6. On the **"Settings"** / **"Keys"** page of the app, add a new key and note down the value after hitting **"Save"**.
+7. Configure the proxy with
+
+```
+   --provider=azure
+   --client-id=<application ID from step 3>
+   --client-secret=<value from step 6>
+```
+
+Note: When using the Azure Auth provider with nginx and the cookie session store you may find the cookie is too large and doesn't get passed through correctly. Increasing the proxy_buffer_size in nginx or implementing the [redis session storage](sessions.md#redis-storage) should resolve this.
+
+### Facebook Auth Provider
+
+1.  Create a new FB App from <https://developers.facebook.com/>
+2.  Under FB Login, set your Valid OAuth redirect URIs to `https://internal.yourcompany.com/oauth2/callback`
+
+### GitHub Auth Provider
+
+1.  Create a new project: https://github.com/settings/developers
+2.  Under `Authorization callback URL` enter the correct url ie `https://internal.yourcompany.com/oauth2/callback`
+
+The GitHub auth provider supports two additional ways to restrict authentication to either organization and optional team level access, or to collaborators of a repository. Restricting by these options is normally accompanied with `--email-domain=*`
+
+NOTE: When `--github-user` is set, the specified users are allowed to login even if they do not belong to the specified org and team or collaborators.
+
+To restrict by organization only, include the following flag:
+
+    -github-org="": restrict logins to members of this organisation
+
+To restrict within an organization to specific teams, include the following flag in addition to `-github-org`:
+
+    -github-team="": restrict logins to members of any of these teams (slug), separated by a comma
+
+If you would rather restrict access to collaborators of a repository, those users must either have push access to a public repository or any access to a private repository:
+
+    -github-repo="": restrict logins to collaborators of this repository formatted as orgname/repo
+
+If you'd like to allow access to users with **read only** access to a **public** repository you will need to provide a [token](https://github.com/settings/tokens) for a user that has write access to the repository. The token must be created with at least the `public_repo` scope:
+
+    -github-token="": the token to use when verifying repository collaborators
+
+To allow a user to login with their username even if they do not belong to the specified org and team or collaborators, separated by a comma
+
+    -github-user="": allow logins by username, separated by a comma
+
+If you are using GitHub enterprise, make sure you set the following to the appropriate url:
+
+    -login-url="http(s)://<enterprise github host>/login/oauth/authorize"
+    -redeem-url="http(s)://<enterprise github host>/login/oauth/access_token"
+    -validate-url="http(s)://<enterprise github host>/api/v3"
+
+### Keycloak Auth Provider
+
+1.  Create new client in your Keycloak with **Access Type** 'confidental' and **Valid Redirect URIs** 'https://internal.yourcompany.com/oauth2/callback'
+2.  Take note of the Secret in the credential tab of the client
+3.  Create a mapper with **Mapper Type** 'Group Membership' and **Token Claim Name** 'groups'.
+
+Make sure you set the following to the appropriate url:
+
+    --provider=keycloak
+    --client-id=<client you have created>
+    --client-secret=<your client's secret>
+    --login-url="http(s)://<keycloak host>/auth/realms/<your realm>/protocol/openid-connect/auth"
+    --redeem-url="http(s)://<keycloak host>/auth/realms/<your realm>/protocol/openid-connect/token"
+    --profile-url="http(s)://<keycloak host>/auth/realms/<your realm>/protocol/openid-connect/userinfo"
+    --validate-url="http(s)://<keycloak host>/auth/realms/<your realm>/protocol/openid-connect/userinfo"
+    --keycloak-group=<first_allowed_user_group>
+    --keycloak-group=<second_allowed_user_group>
+    
+For group based authorization, the optional `--keycloak-group` (legacy) or `--allowed-group` (global standard)
+flags can be used to specify which groups to limit access to.
+
+If these are unset but a `groups` mapper is set up above in step (3), the provider will still
+populate the `X-Forwarded-Groups` header to your upstream server with the `groups` data in the
+Keycloak userinfo endpoint response.
+
+The group management in keycloak is using a tree. If you create a group named admin in keycloak
+you should define the 'keycloak-group' value to /admin.
+
+### GitLab Auth Provider
+
+This auth provider has been tested against Gitlab version 12.X. Due to Gitlab API changes, it may not work for version prior to 12.X (see [994](https://github.com/oauth2-proxy/oauth2-proxy/issues/994)).
+
+Whether you are using GitLab.com or self-hosting GitLab, follow [these steps to add an application](https://docs.gitlab.com/ce/integration/oauth_provider.html). Make sure to enable at least the `openid`, `profile` and `email` scopes, and set the redirect url to your application url e.g. https://myapp.com/oauth2/callback.
+
+If you need projects filtering, add the extra `read_api` scope to your application.
+
+The following config should be set to ensure that the oauth will work properly. To get a cookie secret follow [these steps](./overview.md#generating-a-cookie-secret)
+
+```
+    --provider="gitlab"
+    --redirect-url="https://myapp.com/oauth2/callback" // Should be the same as the redirect url for the application in gitlab
+    --client-id=GITLAB_CLIENT_ID
+    --client-secret=GITLAB_CLIENT_SECRET
+    --cookie-secret=COOKIE_SECRET
+```
+
+Restricting by group membership is possible with the following option:
+
+    --gitlab-group="mygroup,myothergroup": restrict logins to members of any of these groups (slug), separated by a comma
+
+If you are using self-hosted GitLab, make sure you set the following to the appropriate URL:
+
+    --oidc-issuer-url="<your gitlab url>"
+
+### LinkedIn Auth Provider
+
+For LinkedIn, the registration steps are:
+
+1.  Create a new project: https://www.linkedin.com/secure/developer
+2.  In the OAuth User Agreement section:
+    - In default scope, select r_basicprofile and r_emailaddress.
+    - In "OAuth 2.0 Redirect URLs", enter `https://internal.yourcompany.com/oauth2/callback`
+3.  Fill in the remaining required fields and Save.
+4.  Take note of the **Consumer Key / API Key** and **Consumer Secret / Secret Key**
+
+### Microsoft Azure AD Provider
+
+For adding an application to the Microsoft Azure AD follow [these steps to add an application](https://docs.microsoft.com/en-us/azure/active-directory/develop/quickstart-register-app).
+
+Take note of your `TenantId` if applicable for your situation. The `TenantId` can be used to override the default `common` authorization server with a tenant specific server.
+
+### OpenID Connect Provider
+
+OpenID Connect is a spec for OAUTH 2.0 + identity that is implemented by many major providers and several open source projects.
+
+This provider was originally built against CoreOS Dex and we will use it as an example.
+The OpenID Connect Provider (OIDC) can also be used to connect to other Identity Providers such as Okta, an example can be found below.
+
+#### Dex
+
+To configure the OIDC provider for Dex, perform the following steps:
+
+1. Download Dex:
+
+    ```
+    go get github.com/dexidp/dex
+    ```
+
+    See the [getting started guide](https://github.com/coreos/dex/blob/master/Documentation/getting-started.md) for more details.
+
+2. Setup oauth2-proxy with the correct provider and using the default ports and callbacks. Add a configuration block to the `staticClients` section of `examples/config-dev.yaml`:
+
+    ```
+    - id: oauth2-proxy
+    redirectURIs:
+    - 'http://127.0.0.1:4180/oauth2/callback'
+    name: 'oauth2-proxy'
+    secret: proxy
+    ```
+
+3. Launch Dex: from `$GOPATH/github.com/dexidp/dex`, run:
+
+    ```
+    bin/dex serve examples/config-dev.yaml
+    ```
+
+4. In a second terminal, run the oauth2-proxy with the following args:
+
+    ```
+    -provider oidc
+    -provider-display-name "My OIDC Provider"
+    -client-id oauth2-proxy
+    -client-secret proxy
+    -redirect-url http://127.0.0.1:4180/oauth2/callback
+    -oidc-issuer-url http://127.0.0.1:5556/dex
+    -cookie-secure=false
+    -cookie-secret=secret
+    -email-domain kilgore.trout
+    ```
+
+    To serve the current working directory as a web site under the `/static` endpoint, add:
+
+    ```
+    -upstream file://$PWD/#/static/
+    ```
+
+5. Test the setup by visiting http://127.0.0.1:4180 or http://127.0.0.1:4180/static .
+
+See also [our local testing environment](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/contrib/local-environment) for a self-contained example using Docker and etcd as storage for Dex.
+
+#### Okta
+
+To configure the OIDC provider for Okta, perform the following steps:
+
+1. Log in to Okta using an administrative account. It is suggested you try this in preview first, `example.oktapreview.com`
+2. (OPTIONAL) If you want to configure authorization scopes and claims to be passed on to multiple applications,
+you may wish to configure an authorization server for each application. Otherwise, the provided `default` will work.
+* Navigate to **Security** then select **API**
+* Click **Add Authorization Server**, if this option is not available you may require an additional license for a custom authorization server.
+* Fill out the **Name** with something to describe the application you are protecting. e.g. 'Example App'.
+* For **Audience**, pick the URL of the application you wish to protect: https://example.corp.com
+* Fill out a **Description**
+* Add any **Access Policies** you wish to configure to limit application access.
+* The default settings will work for other options.
+[See Okta documentation for more information on Authorization Servers](https://developer.okta.com/docs/guides/customize-authz-server/overview/)
+3. Navigate to **Applications** then select **Add Application**.
+* Select **Web** for the **Platform** setting.
+* Select **OpenID Connect** and click **Create**
+* Pick an **Application Name** such as `Example App`.
+* Set the **Login redirect URI** to `https://example.corp.com`.
+* Under **General** set the **Allowed grant types** to `Authorization Code` and `Refresh Token`.
+* Leave the rest as default, taking note of the `Client ID` and `Client Secret`.
+* Under **Assignments** select the users or groups you wish to access your application.
+4. Create a configuration file like the following:
+
+    ```
+    provider = "oidc"
+    redirect_url = "https://example.corp.com/oauth2/callback"
+    oidc_issuer_url = "https://corp.okta.com/oauth2/abCd1234"
+    upstreams = [
+        "https://example.corp.com"
+    ]
+    email_domains = [
+        "corp.com"
+    ]
+    client_id = "XXXXX"
+    client_secret = "YYYYY"
+    pass_access_token = true
+    cookie_secret = "ZZZZZ"
+    skip_provider_button = true
+    ```
+
+The `oidc_issuer_url` is based on URL from your **Authorization Server**'s **Issuer** field in step 2, or simply https://corp.okta.com .
+The `client_id` and `client_secret` are configured in the application settings.
+Generate a unique `client_secret` to encrypt the cookie.
+
+Then you can start the oauth2-proxy with `./oauth2-proxy --config /etc/example.cfg`
+
+#### Okta - localhost
+
+1. Signup for developer account: https://developer.okta.com/signup/
+2. Create New `Web` Application: https://${your-okta-domain}/dev/console/apps/new
+3. Example Application Settings for localhost:
+   * **Name:** My Web App
+   * **Base URIs:** http://localhost:4180/
+   * **Login redirect URIs:** http://localhost:4180/oauth2/callback
+   * **Logout redirect URIs:** http://localhost:4180/
+   * **Group assignments:** `Everyone`
+   * **Grant type allowed:** `Authorization Code` and `Refresh Token`
+4. Make note of the `Client ID` and `Client secret`, they are needed in a future step
+5. Make note of the **default** Authorization Server Issuer URI from: https://${your-okta-domain}/admin/oauth2/as
+6. Example config file `/etc/localhost.cfg`
+    ```
+    provider = "oidc"
+    redirect_url = "http://localhost:4180/oauth2/callback"
+    oidc_issuer_url = "https://${your-okta-domain}/oauth2/default"
+    upstreams = [
+        "http://0.0.0.0:8080"
+    ]
+    email_domains = [
+        "*"
+    ]
+    client_id = "XXX"
+    client_secret = "YYY"
+    pass_access_token = true
+    cookie_secret = "ZZZ"
+    cookie_secure = false
+    skip_provider_button = true
+    # Note: use the following for testing within a container
+    # http_address = "0.0.0.0:4180"
+    ```
+7. Then you can start the oauth2-proxy with `./oauth2-proxy --config /etc/localhost.cfg`
+
+### login.gov Provider
+
+login.gov is an OIDC provider for the US Government.
+If you are a US Government agency, you can contact the login.gov team through the contact information
+that you can find on https://login.gov/developers/ and work with them to understand how to get login.gov
+accounts for integration/test and production access.
+
+A developer guide is available here: https://developers.login.gov/, though this proxy handles everything
+but the data you need to create to register your application in the login.gov dashboard.
+
+As a demo, we will assume that you are running your application that you want to secure locally on
+http://localhost:3000/, that you will be starting your proxy up on http://localhost:4180/, and that
+you have an agency integration account for testing.
+
+First, register your application in the dashboard.  The important bits are:
+  * Identity protocol:  make this `Openid connect`
+  * Issuer:  do what they say for OpenID Connect.  We will refer to this string as `${LOGINGOV_ISSUER}`.
+  * Public key:  This is a self-signed certificate in .pem format generated from a 2048 bit RSA private key.
+    A quick way to do this is `openssl req -x509 -newkey rsa:2048 -keyout key.pem -out cert.pem -days 3650 -nodes -subj '/C=US/ST=Washington/L=DC/O=GSA/OU=18F/CN=localhost'`,
+    The contents of the `key.pem` shall be referred to as `${OAUTH2_PROXY_JWT_KEY}`.
+  * Return to App URL:  Make this be `http://localhost:4180/`
+  * Redirect URIs:  Make this be `http://localhost:4180/oauth2/callback`.
+  * Attribute Bundle:  Make sure that email is selected.
+
+Now start the proxy up with the following options:
+```
+./oauth2-proxy -provider login.gov \
+  -client-id=${LOGINGOV_ISSUER} \
+  -redirect-url=http://localhost:4180/oauth2/callback \
+  -oidc-issuer-url=https://idp.int.identitysandbox.gov/ \
+  -cookie-secure=false \
+  -email-domain=gsa.gov \
+  -upstream=http://localhost:3000/ \
+  -cookie-secret=somerandomstring12341234567890AB \
+  -cookie-domain=localhost \
+  -skip-provider-button=true \
+  -pubjwk-url=https://idp.int.identitysandbox.gov/api/openid_connect/certs \
+  -profile-url=https://idp.int.identitysandbox.gov/api/openid_connect/userinfo \
+  -jwt-key="${OAUTH2_PROXY_JWT_KEY}"
+```
+You can also set all these options with environment variables, for use in cloud/docker environments.
+One tricky thing that you may encounter is that some cloud environments will pass in environment
+variables in a docker env-file, which does not allow multiline variables like a PEM file.
+If you encounter this, then you can create a `jwt_signing_key.pem` file in the top level
+directory of the repo which contains the key in PEM format and then do your docker build.
+The docker build process will copy that file into your image which you can then access by
+setting the `OAUTH2_PROXY_JWT_KEY_FILE=/etc/ssl/private/jwt_signing_key.pem`
+environment variable, or by setting `--jwt-key-file=/etc/ssl/private/jwt_signing_key.pem` on the commandline.
+
+Once it is running, you should be able to go to `http://localhost:4180/` in your browser,
+get authenticated by the login.gov integration server, and then get proxied on to your
+application running on `http://localhost:3000/`.  In a real deployment, you would secure
+your application with a firewall or something so that it was only accessible from the
+proxy, and you would use real hostnames everywhere.
+
+#### Skip OIDC discovery
+
+Some providers do not support OIDC discovery via their issuer URL, so oauth2-proxy cannot simply grab the authorization, token and jwks URI endpoints from the provider's metadata.
+
+In this case, you can set the `--skip-oidc-discovery` option, and supply those required endpoints manually:
+
+```
+    -provider oidc
+    -client-id oauth2-proxy
+    -client-secret proxy
+    -redirect-url http://127.0.0.1:4180/oauth2/callback
+    -oidc-issuer-url http://127.0.0.1:5556
+    -skip-oidc-discovery
+    -login-url http://127.0.0.1:5556/authorize
+    -redeem-url http://127.0.0.1:5556/token
+    -oidc-jwks-url http://127.0.0.1:5556/keys
+    -cookie-secure=false
+    -email-domain example.com
+```
+
+### Nextcloud Provider
+
+The Nextcloud provider allows you to authenticate against users in your
+Nextcloud instance.
+
+When you are using the Nextcloud provider, you must specify the urls via
+configuration, environment variable, or command line argument. Depending
+on whether your Nextcloud instance is using pretty urls your urls may be of the
+form `/index.php/apps/oauth2/*` or `/apps/oauth2/*`.
+
+Refer to the [OAuth2
+documentation](https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/oauth2.html)
+to setup the client id and client secret. Your "Redirection URI" will be
+`https://internalapp.yourcompany.com/oauth2/callback`.
+
+```
+    -provider nextcloud
+    -client-id <from nextcloud admin>
+    -client-secret <from nextcloud admin>
+    -login-url="<your nextcloud url>/index.php/apps/oauth2/authorize"
+    -redeem-url="<your nextcloud url>/index.php/apps/oauth2/api/v1/token"
+    -validate-url="<your nextcloud url>/ocs/v2.php/cloud/user?format=json"
+```
+
+Note: in *all* cases the validate-url will *not* have the `index.php`.
+
+### DigitalOcean Auth Provider
+
+1. [Create a new OAuth application](https://cloud.digitalocean.com/account/api/applications)
+    * You can fill in the name, homepage, and description however you wish.
+    * In the "Application callback URL" field, enter: `https://oauth-proxy/oauth2/callback`, substituting `oauth2-proxy` with the actual hostname that oauth2-proxy is running on. The URL must match oauth2-proxy's configured redirect URL.
+2. Note the Client ID and Client Secret.
+
+To use the provider, pass the following options:
+
+```
+   --provider=digitalocean
+   --client-id=<Client ID>
+   --client-secret=<Client Secret>
+```
+
+ Alternatively, set the equivalent options in the config file. The redirect URL defaults to `https://<requested host header>/oauth2/callback`. If you need to change it, you can use the `--redirect-url` command-line option.
+
+### Bitbucket Auth Provider
+
+1. [Add a new OAuth consumer](https://confluence.atlassian.com/bitbucket/oauth-on-bitbucket-cloud-238027431.html)
+    * In "Callback URL" use `https://<oauth2-proxy>/oauth2/callback`, substituting `<oauth2-proxy>` with the actual hostname that oauth2-proxy is running on.
+    * In Permissions section select:
+        * Account -> Email
+        * Team membership -> Read
+        * Repositories -> Read
+2. Note the Client ID and Client Secret.
+
+To use the provider, pass the following options:
+
+```
+   --provider=bitbucket
+   --client-id=<Client ID>
+   --client-secret=<Client Secret>
+```
+
+The default configuration allows everyone with Bitbucket account to authenticate. To restrict the access to the team members use additional configuration option: `--bitbucket-team=<Team name>`. To restrict the access to only these users who has access to one selected repository use `--bitbucket-repository=<Repository name>`.
+
+
+### Gitea Auth Provider
+
+1. Create a new application: `https://< your gitea host >/user/settings/applications`
+2. Under `Redirect URI` enter the correct URL i.e. `https://<proxied host>/oauth2/callback`
+3. Note the Client ID and Client Secret.
+4. Pass the following options to the proxy:
+
+```
+    --provider="github"
+    --redirect-url="https://<proxied host>/oauth2/callback"
+    --provider-display-name="Gitea"
+    --client-id="< client_id as generated by Gitea >"
+    --client-secret="< client_secret as generated by Gitea >"
+    --login-url="https://< your gitea host >/login/oauth/authorize"
+    --redeem-url="https://< your gitea host >/login/oauth/access_token"
+    --validate-url="https://< your gitea host >/api/v1"
+```
+
+
+## Email Authentication
+
+To authorize by email domain use `--email-domain=yourcompany.com`. To authorize individual email addresses use `--authenticated-emails-file=/path/to/file` with one email per line. To authorize all email addresses use `--email-domain=*`.
+
+## Adding a new Provider
+
+Follow the examples in the [`providers` package](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/providers/) to define a new
+`Provider` instance. Add a new `case` to
+[`providers.New()`](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/providers/providers.go) to allow `oauth2-proxy` to use the
+new `Provider`.

+
+`oauth2-proxy` can be configured via [config file](#config-file), [command line options](#command-line-options) or [environment variables](#environment-variables).
+
+### Generating a Cookie Secret
+
+To generate a strong cookie secret use `python -c 'import os,base64; print(base64.urlsafe_b64encode(os.urandom(16)).decode())'`
+
+### Config File
+
+Every command line argument can be specified in a config file by replacing hyphens (-) with underscores (\_). If the argument can be specified multiple times, the config option should be plural (trailing s).
+
+An example [oauth2-proxy.cfg](https://github.com/oauth2-proxy/oauth2-proxy/blob/master/contrib/oauth2-proxy.cfg.example) config file is in the contrib directory. It can be used by specifying `--config=/etc/oauth2-proxy.cfg`

Use this option only if you understand the risks and how to manage them. | |
+
+\[<a name="footnote1">1</a>\]: Only these providers support `--cookie-refresh`: GitLab, Google and OIDC
+
+\[<a name="footnote2">2</a>\]: When using the `whitelist-domain` option, any domain prefixed with a `.` will allow any subdomain of the specified domain as a valid redirect URL. By default, only empty ports are allowed. This translates to allowing the default port of the URL's protocol (80 for HTTP, 443 for HTTPS, etc.) since browsers omit them. To allow only a specific port, add it to the whitelisted domain: `example.com:8080`. To allow any port, use `*`: `example.com:*`.
+
+See below for provider specific options
+
+### Upstreams Configuration
+
+`oauth2-proxy` supports having multiple upstreams, and has the option to pass requests on to HTTP(S) servers or serve static files from the file system. HTTP and HTTPS upstreams are configured by providing a URL such as `http://127.0.0.1:8080/` for the upstream parameter. This will forward all authenticated requests to the upstream server. If you instead provide `http://127.0.0.1:8080/some/path/` then it will only be requests that start with `/some/path/` which are forwarded to the upstream.
+
+Static file paths are configured as a file:// URL. `file:///var/www/static/` will serve the files from that directory at `http://[oauth2-proxy url]/var/www/static/`, which may not be what you want. You can provide the path to where the files should be available by adding a fragment to the configured URL. The value of the fragment will then be used to specify which path the files are available at, e.g. `file:///var/www/static/#/static/` will make `/var/www/static/` available at `http://[oauth2-proxy url]/static/`.
+
+Multiple upstreams can either be configured by supplying a comma separated list to the `--upstream` parameter, supplying the parameter multiple times or providing a list in the [config file](#config-file). When multiple upstreams are used routing to them will be based on the path they are set up with.
+
+### Environment variables
+
+Every command line argument can be specified as an environment variable by
+prefixing it with `OAUTH2_PROXY_`, capitalising it, and replacing hyphens (`-`)
+with underscores (`_`). If the argument can be specified multiple times, the
+environment variable should be plural (trailing `S`).
+
+This is particularly useful for storing secrets outside of a configuration file
+or the command line.
+
+For example, the `--cookie-secret` flag becomes `OAUTH2_PROXY_COOKIE_SECRET`,
+and the `--email-domain` flag becomes `OAUTH2_PROXY_EMAIL_DOMAINS`.
+
+## Logging Configuration
+
+By default, OAuth2 Proxy logs all output to stdout. Logging can be configured to output to a rotating log file using the `--logging-filename` command.
+
+If logging to a file you can also configure the maximum file size (`--logging-max-size`), age (`--logging-max-age`), max backup logs (`--logging-max-backups`), and if backup logs should be compressed (`--logging-compress`).
+
+There are three different types of logging: standard, authentication, and HTTP requests. These can each be enabled or disabled with `--standard-logging`, `--auth-logging`, and `--request-logging`.
+
+Each type of logging has its own configurable format and variables. By default these formats are similar to the Apache Combined Log.
+
+Logging of requests to the `/ping` endpoint (or using `--ping-user-agent`) can be disabled with `--silence-ping-logging` reducing log volume. This flag appends the `--ping-path` to `--exclude-logging-paths`.
+
+### Auth Log Format
+Authentication logs are logs which are guaranteed to contain a username or email address of a user attempting to authenticate. These logs are output by default in the below format:
+
+```
+<REMOTE_ADDRESS> - <REQUEST ID> - <user@domain.com> [19/Mar/2015:17:20:19 -0400] [<STATUS>] <MESSAGE>
+```
+
+The status block will contain one of the below strings:
+
+- `AuthSuccess` If a user has authenticated successfully by any method
+- `AuthFailure` If the user failed to authenticate explicitly
+- `AuthError` If there was an unexpected error during authentication
+
+If you require a different format than that, you can configure it with the `--auth-logging-format` flag.
+The default format is configured as follows:
+
+```
+{{.Client}} - {{.RequestID}} - {{.Username}} [{{.Timestamp}}] [{{.Status}}] {{.Message}}
+```
+
+Available variables for auth logging:
+
+| Variable | Example | Description |
+| --- | --- | --- |
+| Client | 74.125.224.72 | The client/remote IP address. Will use the X-Real-IP header it if exists & reverse-proxy is set to true. |
+| Host  | domain.com | The value of the Host header. |
+| Message | Authenticated via OAuth2 | The details of the auth attempt. |
+| Protocol | HTTP/1.0 | The request protocol. |
+| RequestID | 00010203-0405-4607-8809-0a0b0c0d0e0f | The request ID pulled from the `--request-id-header`. Random UUID if empty |
+| RequestMethod | GET | The request method. |
+| Timestamp | 19/Mar/2015:17:20:19 -0400 | The date and time of the logging event. |
+| UserAgent | - | The full user agent as reported by the requesting client. |
+| Username | username@email.com | The email or username of the auth request. |
+| Status | AuthSuccess | The status of the auth request. See above for details. |
+
+### Request Log Format
+HTTP request logs will output by default in the below format:
+
+```
+<REMOTE_ADDRESS> - <REQUEST ID> - <user@domain.com> [19/Mar/2015:17:20:19 -0400] <HOST_HEADER> GET <UPSTREAM_HOST> "/path/" HTTP/1.1 "<USER_AGENT>" <RESPONSE_CODE> <RESPONSE_BYTES> <REQUEST_DURATION>
+```
+
+If you require a different format than that, you can configure it with the `--request-logging-format` flag.
+The default format is configured as follows:
+
+```
+{{.Client}} - {{.RequestID}} - {{.Username}} [{{.Timestamp}}] {{.Host}} {{.RequestMethod}} {{.Upstream}} {{.RequestURI}} {{.Protocol}} {{.UserAgent}} {{.StatusCode}} {{.ResponseSize}} {{.RequestDuration}}
+```
+
+Available variables for request logging:
+
+| Variable | Example | Description |
+| --- | --- | --- |
+| Client | 74.125.224.72 | The client/remote IP address. Will use the X-Real-IP header it if exists & reverse-proxy is set to true. |
+| Host  | domain.com | The value of the Host header. |
+| Protocol | HTTP/1.0 | The request protocol. |
+| RequestDuration | 0.001 | The time in seconds that a request took to process. |
+| RequestID | 00010203-0405-4607-8809-0a0b0c0d0e0f | The request ID pulled from the `--request-id-header`. Random UUID if empty |
+| RequestMethod | GET | The request method. |
+| RequestURI | "/oauth2/auth" | The URI path of the request. |
+| ResponseSize | 12 | The size in bytes of the response. |
+| StatusCode | 200 | The HTTP status code of the response. |
+| Timestamp | 19/Mar/2015:17:20:19 -0400 | The date and time of the logging event. |
+| Upstream | - | The upstream data of the HTTP request. |
+| UserAgent | - | The full user agent as reported by the requesting client. |
+| Username | username@email.com | The email or username of the auth request. |
+
+### Standard Log Format
+All other logging that is not covered by the above two types of logging will be output in this standard logging format. This includes configuration information at startup and errors that occur outside of a session. The default format is below:
+
+```
+[19/Mar/2015:17:20:19 -0400] [main.go:40] <MESSAGE>
+```
+
+If you require a different format than that, you can configure it with the `--standard-logging-format` flag. The default format is configured as follows:
+
+```
+[{{.Timestamp}}] [{{.File}}] {{.Message}}
+```
+
+Available variables for standard logging:
+
+| Variable | Example | Description |
+| --- | --- | --- |
+| Timestamp | 19/Mar/2015:17:20:19 -0400 | The date and time of the logging event. |
+| File | main.go:40 | The file and line number of the logging statement. |
+| Message | HTTP: listening on 127.0.0.1:4180 | The details of the log statement. |
+
+## Configuring for use with the Nginx `auth_request` directive
+
+The [Nginx `auth_request` directive](http://nginx.org/en/docs/http/ngx_http_auth_request_module.html) allows Nginx to authenticate requests via the oauth2-proxy's `/auth` endpoint, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the request through. For example:
+
+```nginx
+server {
+  listen 443 ssl;
+  server_name ...;
+  include ssl/ssl.conf;
+
+  location /oauth2/ {
+    proxy_pass       http://127.0.0.1:4180;
+    proxy_set_header Host                    $host;
+    proxy_set_header X-Real-IP               $remote_addr;
+    proxy_set_header X-Scheme                $scheme;
+    proxy_set_header X-Auth-Request-Redirect $request_uri;
+    # or, if you are handling multiple domains:
+    # proxy_set_header X-Auth-Request-Redirect $scheme://$host$request_uri;
+  }
+  location = /oauth2/auth {
+    proxy_pass       http://127.0.0.1:4180;
+    proxy_set_header Host             $host;
+    proxy_set_header X-Real-IP        $remote_addr;
+    proxy_set_header X-Scheme         $scheme;
+    # nginx auth_request includes headers but not body
+    proxy_set_header Content-Length   "";
+    proxy_pass_request_body           off;
+  }
+
+  location / {
+    auth_request /oauth2/auth;
+    error_page 401 = /oauth2/sign_in;
+
+    # pass information via X-User and X-Email headers to backend,
+    # requires running with --set-xauthrequest flag
+    auth_request_set $user   $upstream_http_x_auth_request_user;
+    auth_request_set $email  $upstream_http_x_auth_request_email;
+    proxy_set_header X-User  $user;
+    proxy_set_header X-Email $email;
+
+    # if you enabled --pass-access-token, this will pass the token to the backend
+    auth_request_set $token  $upstream_http_x_auth_request_access_token;
+    proxy_set_header X-Access-Token $token;
+
+    # if you enabled --cookie-refresh, this is needed for it to work with auth_request
+    auth_request_set $auth_cookie $upstream_http_set_cookie;
+    add_header Set-Cookie $auth_cookie;
+
+    # When using the --set-authorization-header flag, some provider's cookies can exceed the 4kb
+    # limit and so the OAuth2 Proxy splits these into multiple parts.
+    # Nginx normally only copies the first `Set-Cookie` header from the auth_request to the response,
+    # so if your cookies are larger than 4kb, you will need to extract additional cookies manually.
+    auth_request_set $auth_cookie_name_upstream_1 $upstream_cookie_auth_cookie_name_1;
+
+    # Extract the Cookie attributes from the first Set-Cookie header and append them
+    # to the second part ($upstream_cookie_* variables only contain the raw cookie content)
+    if ($auth_cookie ~* "(; .*)") {
+        set $auth_cookie_name_0 $auth_cookie;
+        set $auth_cookie_name_1 "auth_cookie_name_1=$auth_cookie_name_upstream_1$1";
+    }
+
+    # Send both Set-Cookie headers now if there was a second part
+    if ($auth_cookie_name_upstream_1) {
+        add_header Set-Cookie $auth_cookie_name_0;
+        add_header Set-Cookie $auth_cookie_name_1;
+    }
+
+    proxy_pass http://backend/;
+    # or "root /path/to/site;" or "fastcgi_pass ..." etc
+  }
+}
+```
+
+When you use ingress-nginx in Kubernetes, you MUST use `kubernetes/ingress-nginx` (which includes the Lua module) and the following configuration snippet for your `Ingress`.
+Variables set with `auth_request_set` are not `set`-able in plain nginx config when the location is processed via `proxy_pass` and then may only be processed by Lua.
+Note that `nginxinc/kubernetes-ingress` does not include the Lua module.

+```
+It is recommended to use `--session-store-type=redis` when expecting large sessions/OIDC tokens (_e.g._ with MS Azure).
+
+You have to substitute *name* with the actual cookie name you configured via --cookie-name parameter. If you don't set a custom cookie name the variable  should be "$upstream_cookie__oauth2_proxy_1" instead of "$upstream_cookie_name_1" and the new cookie-name should be "_oauth2_proxy_1=" instead of "name_1=".

+## Configuring for use with the Traefik (v2) `ForwardAuth` middleware
+
+**This option requires `--reverse-proxy` option to be set.**
+
+### ForwardAuth with 401 errors middleware
+
+The [Traefik v2 `ForwardAuth` middleware](https://doc.traefik.io/traefik/middlewares/forwardauth/) allows Traefik to authenticate requests via the oauth2-proxy's `/oauth2/auth` endpoint on every request, which only returns a 202 Accepted response or a 401 Unauthorized response without proxying the whole request through. For example, on Dynamic File (YAML) Configuration:
+
+```yaml
+http:
+  routers:
+    a-service:
+      rule: "Host(`a-service.example.com`)"
+      service: a-service-backend

+id: session_storage
+title: Session Storage
+---
+
+Sessions allow a user's authentication to be tracked between multiple HTTP
+requests to a service.
+
+The OAuth2 Proxy uses a Cookie to track user sessions and will store the session
+data in one of the available session storage backends.
+
+At present the available backends are (as passed to `--session-store-type`):
+- [cookie](#cookie-storage) (default)
+- [redis](#redis-storage)
+
+### Cookie Storage
+
+The Cookie storage backend is the default backend implementation and has
+been used in the OAuth2 Proxy historically.
+
+With the Cookie storage backend, all session information is stored in client
+side cookies and transferred with each and every request.
+
+The following should be known when using this implementation:
+- Since all state is stored client side, this storage backend means that the OAuth2 Proxy is completely stateless
+- Cookies are signed server side to prevent modification client-side
+- It is mandatory to set a `cookie-secret` which will ensure data is encrypted within the cookie data.
+- Since multiple requests can be made concurrently to the OAuth2 Proxy, this session implementation
+cannot lock sessions and while updating and refreshing sessions, there can be conflicts which force
+users to re-authenticate
+
+
+### Redis Storage
+
+The Redis Storage backend stores sessions, encrypted, in redis. Instead sending all the information
+back the the client for storage, as in the [Cookie storage](#cookie-storage), a ticket is sent back
+to the user as the cookie value instead.
+
+A ticket is composed as the following:
+
+`{CookieName}-{ticketID}.{secret}`
+
+Where:
+
+- The `CookieName` is the OAuth2 cookie name (_oauth2_proxy by default)
+- The `ticketID` is a 128 bit random number, hex-encoded
+- The `secret` is a 128 bit random number, base64url encoded (no padding). The secret is unique for every session.
+- The pair of `{CookieName}-{ticketID}` comprises a ticket handle, and thus, the redis key
+to which the session is stored. The encoded session is encrypted with the secret and stored
+in redis via the `SETEX` command.
+
+Encrypting every session uniquely protects the refresh/access/id tokens stored in the session from
+disclosure.
+
+#### Usage
+
+When using the redis store, specify `--session-store-type=redis` as well as the Redis connection URL, via
+`--redis-connection-url=redis://host[:port][/db-number]`.
+
+You may also configure the store for Redis Sentinel. In this case, you will want to use the
+`--redis-use-sentinel=true` flag, as well as configure the flags `--redis-sentinel-master-name`
+and `--redis-sentinel-connection-urls` appropriately.
+
+Redis Cluster is available to be the backend store as well. To leverage it, you will need to set the
+`--redis-use-cluster=true` flag, and configure the flags `--redis-cluster-connection-urls` appropriately.
+
+Note that flags `--redis-use-sentinel=true` and `--redis-use-cluster=true` are mutually exclusive.

+title: TLS Configuration
+---
+
+There are two recommended configurations.
+
+1.  Configure SSL Termination with OAuth2 Proxy by providing a `--tls-cert-file=/path/to/cert.pem` and `--tls-key-file=/path/to/cert.key`.
+
+    The command line to run `oauth2-proxy` in this configuration would look like this:
+
+    ```bash
+    ./oauth2-proxy \
+        --email-domain="yourcompany.com"  \
+        --upstream=http://127.0.0.1:8080/ \
+        --tls-cert-file=/path/to/cert.pem \
+        --tls-key-file=/path/to/cert.key \
+        --cookie-secret=... \
+        --cookie-secure=true \
+        --provider=... \
+        --client-id=... \
+        --client-secret=...
+    ```
+
+2.  Configure SSL Termination with [Nginx](http://nginx.org/) (example config below), Amazon ELB, Google Cloud Platform Load Balancing, or ....
+
+    Because `oauth2-proxy` listens on `127.0.0.1:4180` by default, to listen on all interfaces (needed when using an
+    external load balancer like Amazon ELB or Google Platform Load Balancing) use `--http-address="0.0.0.0:4180"` or
+    `--http-address="http://:4180"`.
+
+    Nginx will listen on port `443` and handle SSL connections while proxying to `oauth2-proxy` on port `4180`.
+    `oauth2-proxy` will then authenticate requests for an upstream application. The external endpoint for this example
+    would be `https://internal.yourcompany.com/`.
+
+    An example Nginx config follows. Note the use of `Strict-Transport-Security` header to pin requests to SSL
+    via [HSTS](http://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security):
+
+    ```
+    server {
+        listen 443 default ssl;
+        server_name internal.yourcompany.com;
+        ssl_certificate /path/to/cert.pem;
+        ssl_certificate_key /path/to/cert.key;
+        add_header Strict-Transport-Security max-age=2592000;
+
+        location / {
+            proxy_pass http://127.0.0.1:4180;
+            proxy_set_header Host $host;
+            proxy_set_header X-Real-IP $remote_addr;
+            proxy_set_header X-Scheme $scheme;
+            proxy_connect_timeout 1;
+            proxy_send_timeout 30;
+            proxy_read_timeout 30;
+        }
+    }
+    ```
+
+    The command line to run `oauth2-proxy` in this configuration would look like this:
+
+    ```bash
+    ./oauth2-proxy \
+       --email-domain="yourcompany.com"  \
+       --upstream=http://127.0.0.1:8080/ \
+       --cookie-secret=... \
+       --cookie-secure=true \
+       --provider=... \
+       --reverse-proxy=true \
+       --client-id=... \
+       --client-secret=...
+    ```

+
+OAuth2 Proxy responds directly to the following endpoints. All other endpoints will be proxied upstream when authenticated. The `/oauth2` prefix can be changed with the `--proxy-prefix` config variable.
+
+- /robots.txt - returns a 200 OK response that disallows all User-agents from all paths; see [robotstxt.org](http://www.robotstxt.org/) for more info
+- /ping - returns a 200 OK response, which is intended for use with health checks
+- /metrics - Metrics endpoint for Prometheus to scrape, serve on the address specified by `--metrics-address`, disabled by default
+- /oauth2/sign_in - the login page, which also doubles as a sign out page (it clears cookies)
+- /oauth2/sign_out - this URL is used to clear the session cookie
+- /oauth2/start - a URL that will redirect to start the OAuth cycle
+- /oauth2/callback - the URL used at the end of the OAuth cycle. The oauth app will be configured with this as the callback url.
+- /oauth2/userinfo - the URL is used to return user's email from the session in JSON format.
+- /oauth2/auth - only returns a 202 Accepted response or a 401 Unauthorized response; for use with the [Nginx `auth_request` directive](../configuration/overview.md#configuring-for-use-with-the-nginx-auth_request-directive)
+
+### Sign out
+
+To sign the user out, redirect them to `/oauth2/sign_out`. This endpoint only removes oauth2-proxy's own cookies, i.e. the user is still logged in with the authentication provider and may automatically re-login when accessing the application again. You will also need to redirect the user to the authentication provider's sign out page afterwards using the `rd` query parameter, i.e. redirect the user to something like (notice the url-encoding!):
+
+```
+/oauth2/sign_out?rd=https%3A%2F%2Fmy-oidc-provider.example.com%2Fsign_out_page
+```
+
+Alternatively, include the redirect URL in the `X-Auth-Request-Redirect` header:
+
+```
+GET /oauth2/sign_out HTTP/1.1
+X-Auth-Request-Redirect: https://my-oidc-provider/sign_out_page
+...
+```
+
+(The "sign_out_page" should be the [`end_session_endpoint`](https://openid.net/specs/openid-connect-session-1_0.html#rfc.section.2.1) from [the metadata](https://openid.net/specs/openid-connect-discovery-1_0.html#ProviderConfig) if your OIDC provider supports Session Management and Discovery.)
+
+BEWARE that the domain you want to redirect to (`my-oidc-provider.example.com` in the example) must be added to the [`--whitelist-domain`](../configuration/overview) configuration option otherwise the redirect will be ignored.
