Package: nginx Version: 1.2.0-1~squeeze When a UNIX domain socket permissions are set to allow the primary group of the nginx worker processes to read/write on it, the Nginx worker process fail to access it with a 'permission denied' error logged.
Way to reproduce it: Binding Nginx on PHP-FPM UNIX domain socket PHP-FPM socket configured as follow: - User: www-data - Group: www-data - Mode: 0660 Nginx configured as follow: - Worker processes spawned with the user 'nginx' - User 'nginx' has 'www-data' as primary group Details on the configuration can be found here: http://forum.nginx.org/read.php?2,226182 It would be also nice to check than any group of the Nginx worker processes can be used for setting access permissions on sockets, not only its primary one. I am using Debian 6 Squeeze GNU/Linux 2.6.32-5-amd64 x86_64 --- *B. R.*
