Thinshell 2.5 Kerberos Error SSO

Hello,

We are currently trying to enable the SSO feature of Thinshell but upon login with an AD account we receive the following error:

"The operation being request was not performed because the user has not been authenticated."

This occurs using "Native" mode and auto-loading a .pit file and pnstc.

If I launch pnstc with the same .pit file but specifiy my credentials it pushes this to the session broker and then our terminal servers.

I attempted this on a couple of machines and was wondering if anyone has any suggested fixes.

Thanks!

Andrew
