SSO setup for CUCM 12.5 and ADFS4.0

Hello,

 

I am working on setting up SSO for CUCM 12.5 SU2.  The IDP system is ADFS4.0 on Windows server 2019.  We are using certificates signed by our CA.  I have found documentation to integrate with ADFS2.0 and 3.0.  Has anyone had success getting this integration to work? 

 

When trying to run the SSO Test I get these errors: 

Error from Windows events. Event ID 364 and 317

Error from CUCM after pressing Run SSO Test: "Invalid Status code in Response. This may be caused by a configuration error in the IDP. Please check the IDP logs and configuration."

 

Any guides or lessons learned would be greatly appreciated.

Have a look on below thread regarding ADFS 4 on Win server 2016.

We have the exact same setup as you and it works. AFAIK the documentation for how to set this up for ADFS 2.0 still apply for newer versions. It is very picky in the setup, you’ll need to go through it with a fine thought comb and give attention to all the details, even though it might seem irrelevant or small.

Thanks for the feedback Roger and Nithin.  I will go through the guide again and look over the comments from that board.
