The Samba code works correctly on Linux, however to get users, you need
to set up nsswitch and its required links. Now I know you say that AIX
does not use these, but it must use something else instead, it is
probably something in this link that doesn't work. I can't test this,
but I feel that trying to use a 64bit Samba with 32bit tools isn't a
good idea, but then what do I know ?
I am fairly certain that your problem isn't a Samba one, but an AIX one.
Could you build Samba yourself ?
If you could, you could build it all into the AIX version of
/usr/local/samba and that way you will get binaries etc built for your arch.
