Dude, if it's this easy that would be SWEET!  The How To's for TLS/PEAP
are a little outdated so I'm working on getting the CA working now
(CA.all doesn't exist anymore.)

I'm ALL over this ASAP!  Thanks!

Gary

If you're using version 2.0.5 or higher you can do this with unlang as
follows.  This example sets the vlan based on the user's DN, but you
should be able to modify it to look at your group membership attribute. 
Repeat for all relevant ldap groups.

if (control:Ldap-UserDn =~ /ou=div,o=org/i) {
        update reply {
             Tunnel-Type := "VLAN"
             Tunnel-Medium-Type := "IEEE-802"
             Tunnel-Private-Group-Id := 9
        }
}
