APM - Azure AD integration with Oauth

Hi,

I have a client that wants to centralize authentication to internal services (Intranet, private applications, etc) with Azure AD via APM using the Oauth protocol.

When a user tries to access an internal resource, transparently send the credentials to the APM, it will validate the credentials with Azure AD and the APM will allow access if the credentials are correct.

The communication between APM and Azure AD, from what I have read, can only be done through Oauth. I have looked for some examples of how this could be done, but it is not entirely clear to me. Has anyone done that? Do you know of a Cookbook that tells you how to do it?

Thanks
