Well, since this system doesn't have local files can you use secldapclntd?
This will solve your local user problem (which is what I was driving at
:-) ) by pointing to LDAP and making the users appear local. There's also
the possbility of WINBIND depending on how you want to approach the users.
secldapclntd can be implemented in a few minutes.

As long as your smb.conf points to the same containers, you should see that
you're looking for.

I'm working on a paper for AIX people on how to approach user/group since
there are several options available.
