Thanks for the quick response.

Our Red Hat installation uses the UPG convention by default, so I simply 
trying to support it.  I will discontinue its use if I can't find a 
workaround.  Samba 3 with ACL support and ntconfig.pol policies make it 
somewhat redundant.

But, yes, that group cannot be found.  The UPG is is the primary group 
of the user, and I _think_ Samba wants to chgrp the user to a different 
group.  This fails because the UPG is not a Samba group.  If I map the 
private group to Domain group of the same name, I run into netbios name 
duplication problems.
