Is there any reason why Samba could not fully support PAM authorization and
session management functions (which typically don't handle passwords at all)?
Currently, the PAM support in Samba does call pam_acct_mgmt() to verify
authorization; does it do this only when PAM in used for authentication as
well? Would pam_open_session() and pam_close_session() fit in Samba, given
that many authenticated Samba "sessions" last only seconds (or less)? If
implemented, perhaps this should follow the lead of the experimental utmp

PAM's authentication API as it stands now is not a good fit for what Samba
does. Many people seem interested in enhancing PAM to allow it to work with
Samba's encrypted password mode, but it would be premature to try
incorporating this into Samba.
