According to this: http://blogs.technet.com/b/askds/archive/2012/09/27/ad-fs-2-0-relaystate.aspx
The RelayState parameter was supported as of ADFS 2.0 Update 2 with an edit to web.config. There is no information on RelayState support with ADFS 3.0 in WS 2012 R2, so I assume that RelayState is supported without any additional configuration. Is this correct?
We are having trouble passing a RelayState URL created with the URL generator to a third party STS. We are trying to figure out if the issue is with ADFS passing the URL or on the 3rd party STS. Can someone confirm if there is any additional configuration required on ADFS 3.0 to pass RelayState (like it was in ADFS 2.0)? Or is this supported right out of the box?
thanks,
Dustin
