This fell through the cracks over the summer holiday time:
The 2nd edition of the Patterns & Practices “claims guide” has been released. This is excellent!
We added a lot of content around ADFS, Access Control Service, REST and SharePoint. All source code is available as well!
Grab it from: http://msdn.microsoft.com/en-us/library/ff423674.aspx

I am trying to set up the following chain: SharePoint 2013 – IdSrv – ADFS, where SharePoint is the RP for IdSrv and IdSrv is an RP for ADFS, using WSFederation and HRD. from sharepoint I go to HRD, select ADFS, IdSrv correctly redirects me to ADFS, I log in and then instead of issue/wsfed redirecting me to sharepoint I am sent to the STS’s signin page. I have unchecked the role requirement checkbox and also checked the all user can request tokens checkbox. Am I missing something? I plan on doing a complete write up of the process for a dutch sharepoint community.
Any help would be much appreciated.
ADFS should redirect back to issue/hrd. You need to set this up manually in ADFS (don’t use the metadata).
