Hello @LazarusG
sorry for the late response - I was off for vacation.
Certainly you can continue using AD Query for learning login events, however the Identity Collector presents the recommended method for integrating to on-premises Active Directory services as explained in sk179544 - specially video #4.
In video #5 you can see the details of the status when AD Query and ID Collector are enabled. I recommend disabling AD Query once you verified ID Collector integration is working as expected.
best regards
peter
