I believe it will still connect to the LDAP and GC ports, just the protocol
changes. To my knowledge going with the AD provider might help but you're
using LDAP for a reason instead I assume. Thinking about it though LDAP and
CLDAP calls will still connect to those ports.

What cybersecurity is reporting off of is a particular event number on its
AD controllers. which is showing a connection to a LDAP port.
Is there another (better) event that it should be looking for instead?
I.e., it should be flagging a simple binding only to an LDAP port.
We have a MS consultant, but they're not sssd-knowledgeable.
