hi
I would like to enter in the web-app in a W 2008 R2 with RDS with SSO (single sing on)
It is annoying for the users to enter the credentials twice.
My clients are WXP with SP3
So.
a) I did a auto-self certificate in the IIS of RDS server

b) I configured my RemoteApp Manager settings for Certificates.

b) I change de CredSSP options in the client

(only the first part of this KB)
c) I exported the RDS server certificate
(copy to File…)

d) I installed this certificate In the windows XP SP3 client
And that is. The user runs the application with SSO
NOTE: that tip doesn’t work with Windows 7
FOR WINDOWS 7
Change the gpo (in domain) or gpedit.msc (locally)
You need to change the “Allow Delegating Default Credentials” and add the RDS server.
