This article explains how to use Active Directory with Amazon AppStream 2.0. You can join the Always-On and On-Demand Windows fleets and image builders to domains in Microsoft Active Directory and use AWS Directory Service for Microsoft Active Directory to create an Active Directory domain. By joining AppStream 2.0 to your Active Directory domain, you can access Active Directory resources, use Group Policy settings, stream applications that require authentication, and apply enterprise compliance and security policies. Currently, Linux fleets and image builders do not support domain join.
