PAM auth?

Hi,

I'm running 9.1.2 on FreeBSD 9, installed via OS vendor package, and
trying to get PAM auth to work.

From what I've read, this should be as simple as the following
/usr/local/share/postgres/pg_hba.conf:

host     all             all     0.0.0.0/0               pam  postgresql
local    all             all     0.0.0.0/0               pam  postgresql

(I'm using my firewall for access control.)

After restarting postgresql, users are still not being prompted for
passwords. Here's my /usr/local/etc/pam.d/postgresql file:

auth            sufficient      /usr/local/lib/pam_ldap.so      no_warn
auth            required        pam_unix.so             no_warn try_first_pass nullok
account         include         system
session         include         system
password        include         system

Hoping to see some auth debugging, I set log_min_messages and
client_min_messages to debug5. Syslog sends local0 to
/var/log/postgres, but nothing on auth appears.

Any suggestions on how I can debug postgres authentication? Or am I
looking in the completely wrong place?

Thanks for any advice,
==ml
