This adds ".inc.php" files to the included overrides while maintaining
support for existing ".inc" files previously included via overrides.
Roundcube itself uses "inc.php" files and these overrides are expected
to match that format. Switching to "inc.php" both tells the user that
these need to be proper php files and conveys they are used for changing
the same settings that Roundcube's inc.php files modify.
As per discussion in #2360: The front container (nginx reverse proxy) is
already logging all requests, disable the access logs for apache2 in the
roundcube container completely.
Roundcube webmail is accessed through the nginx reverse proxy in the
front container. Each access logline logged by apache2 in the roundcube
container did not contain the actual client IP address, but the IP
address of the front container, for example:
> 192.168.203.3 - - [28/May/2022:12:33:52 +0000] "POST /?_task=mail&_action=refresh HTTP/1.1" 200 677 "https://[REDACTED]/roundcube/?_task=mail&_mbox=INBOX" "Mozilla/5.0 (X11; Linux x86_64; rv:100.0) Gecko/20100101 Firefox/100.0"
^
IP address of the front container
By enabling the apache2 remoteip module and configuring it to get the
actual client IP address from the X-Forwarded-For header, it logs the
correct client IP address to the access log.
1754: centralize Webmail authentication behind the admin panel (SSO) r=mergify[bot] a=nextgens
## What type of PR?
Enhancement: it centralizes the authentication of webmails to the admin interface.
## What does this PR do?
It implements the glue required for webmails to do SSO using the admin interface.
One of the main advantages of centralizing things this way is that it reduces significantly the attack surface available to an unauthenticated attacker (no webmail access until there is a valid Flask session).
Others include the ability to implement 2FA down the line and rate-limit things as required.
