How to enable ldaps

LDAPS can be enabled at install time, if you haven't enabled it at install time, 
you have to modify the URL used by LDAP on all servers, and make sure that
ldap_starttls_supported is set to zero in the localconfig

I.e., su - zimbra zmlocalconfig -e ldap_master_url = ldaps://mymaster.somewhere.com:636 zmlocalconfig -e ldap_url = ldaps://myreplica.somewhere.com:636 zmlocalconfig -e ldap_starttls_supported = 0
