I have setup a RD Web Access portal with RemoteApps (Word, Excel etc) as well as the Desktop RemoteApp. All the Remote Desktop Services roles are installed on the same machine except for the Virtualization Host role. However Single Sign-On does not work for the Desktop RemoteApp as the user is required to enter their logon credentials again. I have installed a self signed certificate (for now) and no certificate errors are present when connecting to the RemoteApps. Is this normal to re-enter user credentials when accessing the Desktop RemoteApp or have other people encountered this problem before?
