You're right Phil.  It's been too long since I wrote that patch.  

Gary: Forget what I said about comparing User-Name in inner vs outer tunnels.  You would need to look at the User-Name attribute vs. the username contained in the MSCHAP response. If you have a test server, I would test it with 2.1.10 after you get Aruba not to be the termination point for PEAP..
