If I'm writing ASP.NET Web App that uses Azure Active Directory for authentication, how should I perform authentication of the RWS Client Calls in order to avoid double authentication?
I've noticed that RWS is using Basic Authentication on the Web Service side, but Azure AD can provide me with OAuth2 token. Can I use that OAuth2 token to connect to RWS like it can be used to access EWS?
