Strange behavior when using Kerberos SSO - Shell Folders, etc.

We have configured a custom .PIT to a remote app (hosted on XP) for users to launch directly from a network share. Authentication has been set to use Kerberos. Print re-direction, drive re-direction, etc are also enabled.

On the hosted desktop we have set the user shell folders to point their documents folder to their home directory.

When accessing the desktop via the .PIT file, the app opens up and runs fine but... The shell folder has not re-directed to the home directory, local printers and drives are not passed through.

If we change the .PIT so users have to manually authenticate (no Kerberos), everything works correctly...

Is this a known issue?

Any ideas?

Cheers,

Dan.
