Does this explain why uid shows fine but not gid?

Thank you,

I have some older fedora clients where the group name shows up fine, but newer CentOS 6 clients have the group name for NFS mounts show up as "nobody". The username shows up fine but the group name shows up as "nobody".

This is a know issue (or a feature) with nfs4.

https://access.redhat.com/kb/docs/DOC-49407

Or some page that is more accessible:

http://serverfault.com/questions/98741/files-mounted-over-nfsv4-are-owned-by-4294967294-uids-and-gids-match

In short, "If the NFSv4 client and server domain names do not match, all the usernames will show up as nobody."
