Deployment options for application and connections

Hey guys,
I currently have Parallels Remote Application Server being deployed through SCCM 2012 which seems to work ok for the most part. It seems the "single sign-on" component is installed and enabled but it doesn't come up as an available option in the drop down lists when setting up a connection. Are there any particular steps required to rectify this?

On the topic of setting up the connections, I would like to deploy a basic connection with single sign-on as the authentication method to all users on these computers. I can't seem to find a way to do this. Are their any registry items, or group policy templates I can use for this?

Cheers,
Brandan
