Hi,

thanks to this list I now have postfix talking to saslauthd.

My saslauthd shall authenticate via pam_mysql. Therefore I created the
file /etc/pam.d/smtp as follows:
auth required pam_mysql.so user=maildaemon host=xy passwd=xxxxxxxx
db=dexter-sys table=mbs usercolumn=username passwdcolumn=password crypt=0

The query is actually run on server xy (checked the mysql log) and it is
correct. But I keep getting the following in /var/log/auth.log:

Jun 29 18:02:36 saslauthd[17541]: rel_accept_lock : released accept lock
Jun 29 18:02:36 saslauthd[17542]: get_accept_lock : acquired accept lock
Jun 29 18:02:36 saslauthd[17541]: (pam_unix) could not identify user
(from getpwnam(mail-client-1))
Jun 29 18:02:36 saslauthd[17541]: DEBUG: auth_pam: pam_acct_mgmt failed:
User not known to the underlying authentication module
Jun 29 18:02:37 saslauthd[17541]: do_auth : auth failure:
[user=mail-client-1] [service=smtp] [realm=] [mech=pam] [reason=PAM acct
error]

The thing I'm most concerned about is the pam_unix line. Where does that
come from?

Any ideas what I'm missing? How could I turn on more sasl/pam debugging?

Thanks

Eddy
