I have a customer that would like to setup users from siteA.com to be able to log into RDS and get the full desktop to RDS servers in siteB.com but use credentials for siteA.com. SiteA.com and siteB.com are completely different forests. I have looked around and have gotten ADFS setup that works between the two sites but not sure how to integrate ADFS with RDS Gateway. Especially when I look at setting up the RD CAP rules I can not see the other domain users.
Many thanks in advance for an assistance.
