Hello there,
Channel-binding tokens help secure LDAP authentication over SSL/TLS against man-in-the-middle attacks.
The default port for LDAP is port 389, but LDAPS uses port 636 and establishes SSL/TLS upon connecting with a client.
You must enable LDAP auditing to get suitable logs to identify the LDAP authentication method
Open Registry Editor. Go to HKEY_LOCAL_MACHINE → SYSTEM → CurrentControlSet → Services → NTDS → Diagnostics.
Hope this resolves your Query !!
