Is there any chance to connect to Active Directory with SSL connection on port 636?
Connection without SSL on port 389 is OK.

This is how you could connect::

"LDAP - Port number" - 0
"LDAP - Server Name" - ldaps://ipaddress:636

In /etc/ldap.conf must be:
TLS_REQCERT never

+ restart apache server

Then, I can connect correctly.
