local_recipient_maps into an ldap

[Nicolas Michel]

Hello, I have a zimbra server for managing mail accounts. I have a postfix mail server before it. Mails from outdoor arrive on that server before being relayed to the zimbra server. I want to search from the postfix server into the ldap of zimbra the users/aliases to reject every mail destinated to an unknown user. Actually, I need to create a system account for any new user, and create an alias into /etc/aliases. I have postfix-2.1.5 I set this into my main.cf : local_recipient_maps = ldap:/etc/postfix/ldap-localusers.cf In that file (ldap-localusers.cf), I set this : server_host = zimbra.pcsol.be search_base = ou=people,dc=pcsol,dc=be query_filter = (&(mail=%s)(accountStatus=active)) result_atribute = uid bind = no When I test that configuration with postmap I get no output, nothing. If I remove the "bind = no" line, I get an error : postmap -q 'n...@pcsol.be' ldap:/etc/postfix/ldap-localusers.cf postmap: warning: dict_ldap_connect: Unable to bind to server ldap://zimbra.pcsol.be:389 as : 2 (Protocol error) Do someone have an idea?? Thank you, nm
