ADFS setup with multiple domains RRS feed

  • General discussion

  • I’m trying to setup a little proof of concept ADFS on 2012 R2. We’re going to develop our own app but I need to make sure ADFS works first to avoid chasing down any problems in our app that are caused by a misconfigured ADFS.

    I’ve setup a sample site using the instructions from

    and it seems to work when everything is on the same domain.

    What I want to do is allow for SSO from a 2<sup>nd</sup> domain but I can’t figure out what to setup and where.

    There is no trust between the two domains. What I’m trying to simulate is 3<sup>rd</sup> party connecting (I’ve skipped the proxy/dmz stuff for now, I just want to see if I can get this working)

    My current setup is as follows:

    Domain A:

    - AD server

    - ADFS server

    - IIS server running the little claims app from the 2<sup>nd</sup> link

    Domain B:

    - AD and ADFS server on one machine

    - Client joined to domain B

    What I would like to do have a client on domain B browse to and have B logged in automatically. Similarly, if a user on domain A goes to that same URL, it should also log them in automatically (which is does now)

    Can someone help me figure out what to configure and where?
