Our Remote Desktop server (2008 R2) is also hosting the IIS ADFS site. ADFS works beautifully for internal and external clients.
Except, if I try to connect with a service that uses ADFS from the Remote Desktop session host server that also hosts IIS.
When I do, transparent authentication does not work, and instead I get continual username/password prompts followed eventually by the obligatory IIS error:
Server Error in Application "DEFAULT WEB SITE/ADFS/LS"
Internet Information Services 7.5
Error Summary
HTTP Error 401.1 - Unauthorized
You do not have permission to view this directory or page using the credentials that you supplied.
What could this be?
Bear in mind that I have verified the authentication settings are set to default on the Default Website/adfs and Default Website/adfs/ls folders respectively.
