Any idea? > Please be collaborative, and show the infos that we need to see in order to help you. This is described in the DEBUG README. In particular: - show 'postconf -n' output - show master.cf - show NORMAL logs (not verbose) also, it would be appropriate to test the SAME config with ldap and with hash, to make sure that the problem only happens with ldap.
