Hello Patrick,
Do you mean for IMC Operators to be authenticated via LDAP/S to an AD DC when logging into the web interface? That runs on whichever port you choose in the IMC settings, though the defaults are TCP/UDP
389 for LDAP and
636 for LDAPS (based on AD defaults).
You can find those configurations in IMC via
System > Operator Management > Authentication Server page.
