Setting up the REST authentication password provider module (optional, advanced)

The playbook can install and configure matrix-synapse-rest-auth for you.

See that project's documentation to learn what it does and why it might be useful to you.

Adjusting the playbook configuration

Add the following configuration to your inventory/host_vars/matrix.example.com/vars.yml file (adapt to your needs):

matrix_synapse_ext_password_provider_rest_auth_enabled: true
matrix_synapse_ext_password_provider_rest_auth_endpoint: "http://matrix-ma1sd:8090"
matrix_synapse_ext_password_provider_rest_auth_registration_enforce_lowercase: false
matrix_synapse_ext_password_provider_rest_auth_registration_profile_name_autofill: true
matrix_synapse_ext_password_provider_rest_auth_login_profile_name_autofill: false

Authenticating only using a password provider

If you wish for users to authenticate only against configured password providers (like this one), without consulting Synapse's local database, feel free to disable it:

matrix_synapse_password_config_localdb_enabled: false

Installing

After configuring the playbook, run the installation command: just install-all or just setup-all
