[Samba] winbind on AIX

I was doing some research on this a couple months ago for FreeBSD.
FreeBSD's NSS implementation was designed just for small things like
LDAP and the like. It wasn't fully implemented. As such, I was not
able to find a way to implement the dynamic accounts that windbind
provides. Hopefully this has changed, but from what I know, if there
is no complete NSS implementation, then this is not possible -- AIX
might be an exception. :( Anyone out there have any better news?
