[Samba] Update: Winbind+nss working on one centOS 5.2 box but not another

Something is not right with the group mapping, but I am unsure what.

getent returns different a primary GID for a given user on each box and
the group mapping differs in each case:

Box A:

//user at host//:~$ getent group 10012
OURDOMAIN\domain users:*:10012:

Box B:

//user at host//:~$ getent group 10004
OURDOMAIN\domain users:*:10004:

When I do a long file listing winbindd is printing stuff like this:

[14855]: getpwuid 10082
