Yes. I am sure the issue is not with ldap it's self but with courier. When I set the Auth method to ldap in courier I can watch the syslog and see the mail being delivered so I am sure ldap is fine. I can also use softerra ldap admin and connect fine so...I am pretty sure the issues with courier, that is the only thing that has changed.
up your loglevel in slapd.conf, and watch what happens. try 256.
