Hello, I'm trying to install a second zimbra instance for LDAP replication.

The ldap master host is c.correo, and the replica is d.correo. After the installation, I see in the replica's zimbra log:

slap_client_connect: URI=ldap://c.correo.uc.edu.ve:389 Error, ldap_start_tls failed (-11)

So, it can't connect to the ldap master. I made a manual test without TLS

ldapsearch -x -H ldap://c.correo -D cn=config -w mypwd -b dc=mydomain 'uid=me'

and it works. But when I try using TLS

ldapsearch -x -Z -H ldap://c.correo -D cn=config -w mypwd -b dc=mydomain 'uid=me'

It answers:

ldap_start_tls: Connect error (-11)
ldap_result: Can't contact LDAP server (-1)

So, it seems that the ldap master host is not answering TLS connections. How can activate TLS answers in zimbra's openldap?

Thanks in advance.
