OAuth, reverse proxy, real port number #9952
Description
Hi everyone,
i am running Roundcube 1.6.11 within mailcow docker container, having nginx proxy in front of it. First i've successfully configured roundcube-oauth plugin, which uses HTTP_X_FORWARDED_PORT for redirect_uri composition (if present). Ofcourse I would like to use native Roundcube OAuth support, but it composes the redirect_uri using $_SERVER['SERVER_PORT'] as can be seen in
i think this could be enough to solve it (patch for version 1.6.11)
