Using LDAP Variables with Terminal Server Favorites

I've been evaluating the 4100 unit at our company for the last few weeks and the following request has been made since it was supposedly shown in a demo.

 

 

We want our remote users to authenticate to the firepass and then either using a terminal server favorite or some sort of network access favorite, create an icon automatically that has the user's internal workstation information retrieved from ldap authentication and tie that into microsoft's remote desktop connection program. I'm told it can be done in the 6.x version of the software. I'm supposed to be able to use session variables for the host field in terminal server for example but I can't get that to work. Anyone tried doing the same thing or very close to this and made it work? Help!!!
