We use Active Directory as our Enterprise Login Provider. When a user is disabled or removed in Active Directory, they aren't removed from the list of users in ArcGIS Enterprise. I understand not removing a Level 2 named user as they may own items or groups. But since Level 1 Named Users cannot own data or groups, it would be helpful in order to keep a clean list of users to either have the system automatically when they no longer appear in the Enterprise Login Provider or build into the Python API the ability to query the users that no longer exist in the identity provider.
