Is it possible to configure Oauth based login in AEMaaCS for authors

Hi ​@urvashiagarwal 
 

Yes, OAuth works in AEMaaCS for authors, but you'll configure it differently:

• Keep using Azure AD for user authentication
•  Add Adobe IMS as the OAuth broker
•  Configure federation in Adobe Admin Console
•  Don't try to configure OAuth directly in AEM

The user experience remains the same (SSO with Azure AD), but the technical implementation changes to comply with AEMaaCS architecture.
