Relying party vs application groups in ADFS

I am trying to understand the authentication in .NET web applications using ADFS.

I followed the example in Microsoft documentation and I was able to handle the authentication of my app via ADFS. The given example adds application in a application group of adfs

Few of the examples adds replying party trust instead of application group.

I apologize if it sounds naive but I need to know the difference between these two and how it affects .NET applications

Solution

  • If you use WS-Fed or SAML, the client is a relying party (RP).

    If you use OpenID Connect / OAuth, the client is inside an application group. But functionally, it's the same as a RP.
