I rebuilt OpenPAM with debugging info and looked at what was happening.
It turned out that it was not able to resolve pam_get_pass from the
module and would then state (confusingly) that the module didnt exist
'no pam_pgsql.so found' is bogus. The port has patches which remove
these symbols and I managed to get it working (mostly) by putting those
functions back. Now I can successfully get past authentication with this
module but when I try and login to dovecot it passes down the PAM chain
into pam.d/other and seems to choke. I suppose this is because there is
no local user which matches the user/pass and pam_unix doesn't like
that. If I remove pam_unix from the chain then Dovecot (my test program)
crashes while trying to continue post-auth. If you'd like I can provide
lots of logged openpam debug info and do testing.
