On the Fedora client my user is a member of ten groups, including my own. On the server my user is a member of seven groups, including my own and the web_prog group in question here.

Where can I look to find if there are "still" limitations on the number of groups passed to the server?

Anybody have a response to my question about idmapd requiring UID and/or GID numerical synchronization between client and server?
