Qlik Alerting doesn't provide direct integration with the Active Directory. It uses to sync users directly from Qlik Sense. We can't even import the CAD groups in Qlik Alerting which makes it difficult to manage groups as people come in and go from the organization and we manage the entire thing from CAD.
It will be good to see Qlik Alerting getting integrated with CAD so that we manage the user base quite efficiently without relying on the Qlik Sense user base.
