PAM itself is agnostic as far as local v. remote users are concerned; the API
allows for both or either. With individual PAM modules, you'll find some that
work well for remote users; some that are explicitly bound to local databases;
and some which do silly things like calling getpwnam() when they shouldn't,
causing them to break when they shouldn't. So whereas PAM itself should not
be incompatible with the design of a member server, the possible PAM configs
that can be supported at this point may be fairly limited.

I think it's clear that disabling an account in User Manager should cause the
account to be disabled in Samba's passdb. First, PAM itself doesn't have an
API for /changing/ the status of accounts, so it's not clear how one would
code this portably. Second, using only the passdb gives admins more
flexibility: if they want other services to honor the account flags from the
Samba passdb, they can opt-in to this arrangement using pam_smbpass.
