This cloud wiki setting specifies that the server should change its actual and effective group identity after acquiring the wiki database and starting the http server. You may either use the group's numerical identifier, or a symbolic identifier, like "nobody".
Like set-uid, this setting is often used on POSIX systems where Cloud Wiki must be started as root to listen to ports below 1024 to drop root privileges.
This setting was introduced in Version 2.0, and will have no effect on servers running a previous version of Cloud Wiki.
You should reboot the server after changing this setting.
This node is a part of the cloud wiki manual.
