Hey @abe1 ,
Following up on this post as we have recently released the AAD integration feature: Automation Cloud(tm) Previews: Azure AD Integration for enterprise and OAuth 2.0 for 3rd party apps
The AAD connection is configurable in Automation Cloud and Automation Hub users can leverage as now Automation Hub is a service within Automation Cloud. See here how to enable the Automation Hub service in Automation Cloud: Enabling Automation Hub in Automation Cloud.
Let us know if you have further questions on this one.
Thanks!
