You have enabled new LDAP feature on MTA object and would like to use it in Outlook client, for instance.
The LDAP service enabled and configured on MTA uses "GW" LDAP syntax.
For Base DN use o=<GW system name> to search for all users from the GW system.
If you want to limit a search, use "ou" for a domain or a Post Office, i.e. ou=<post office>,ou=<domain>,o=<gw system name>.
For authentication use GW user credentials. The easiest approach would be to use a user preferred email address as a login name. Otherwise you would need to use cn=<user>,ou=<po>,ou=<domain>,o=<system>.
