[Samba] 2 Servers different gid?

Hi All,

I have 2 servers both running a compiled version of samba and winbind. They
use my Windows Active Directory for user authentication via kerberoes. All
that works fine and I can see and authenticate as any user. Every user on
both machines have the same uid, the problem is the groups from the windows
domain have different gid¹s on each of the servers. I am using nfs to export
the file-system from one machine to another so I need the gid¹s to match up.
I do not know what I am doing wrong. Here is some info on each of the
servers.

Server 1

)

AS YOU CAN SEE FROM THE DIFFERENT id COMMANDS ON THE SEPARATE SERVERS THAT
THE GID DON¹T MATCH, THE SAMBA CONFIGS FOR EACH SERVER ARE BELOW. THANKS IN
ADVANCE FOR ANY HELP YOU MIGHT BE ABLE TO GIVE ME.
