Show us your /etc/sasl2/smtp.conf.

Mine is:

pwcheck_method: authdaemond
log_level: 3
mech_list: PLAIN LOGIN
authdaemond_path: /var/lib/courier/authdaemon/socket

In my case, postfix authenticate on the Courier-imap authdaemond while
authdaemond authenticate users in a MS AD server.

There should be some way to auth postfix using pam... but I think
smtpd.conf should be something like:

pwcheck_method:pam

Good Luck

Hi,

  I configured my PAM (using nsswitch.conf) to auth against a LDAP
server. Everything works fine and now I want to setup postifix to
permit only authenticated users to send e-mail through my smtp server.
But when I try to auth via smtp client, I got the following message on
/var/log/message:
