User Impersonation in Unified Interface Apps– 1 Minutes
With the new Unified Interface apps for Dynamics 365, it is now possible to "log in" as another user. This will be a major benefit to administrators/customizers as they troubleshoot issues on behalf of their users. The reason this is possible is because most (all?) of the data interactions in Unified Interface apps are done through the API, and the API supports user impersonation!
