Hi I am facing following issue for single sign out in ADFS 2.0.
I am using ADFS 2.0 as RSTS Another ADFS 2.0 is registered as claim provider and is configured for Forms authentication.
I have 4 relying parties (RPs) hosted on another IIS server m/c.
I am opening all the 4 RPs in IE after authenticating against Claim Provider. Sign-out works perfectly fine for the first time. But if I sign-in again and click on sign-out ,any one of the RP application remains signed-in after refresh.I could also see the Auth cookie remaining there after sign-out is processed by the ADFS/LS site.
Note: single sign-out work correctly for multiple sign-in and sign-out if the count of RP apps is restricted up to 3.
Am I missing any settings in RSTS? How R-STS remembers all the RPs for which it's creating the signout cleanup request (wa=wsignoutcleanup1.0)? If it's a known issue in ADFS2.0, is it resolved in higher version of ADFS (3.0) any guess?
Thanks in advance.
