There is a local account "demir" cause I can send email to demircc.kou.edu.tr. I also tried with mail : demir in ldif. I got the same "unknown user" problem. I used ldapsource_query_filter = (uid=%u) this time cause uid=user in ldif.

However, email is bounced back to sender cause user ldap_test is not found. Am I doing something wrong? I appreciate any help. Thank you.
