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.. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

This won't work for the OP even under 2.1.10, because his Aruba kit is terminating the PEAP, and then proxying the EAP-MSCHAPv2 as plain MS-CHAPv2, so (as advised elsewhere) he'll still need to change that. You're almost certainly right about the cause/fix. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html

The issue I'm thinking of is one we talked about quite a while ago (I asked if you could test it). It's the one where the case (i.e., upper vs. lower) of the User-Name differs between the inner and outer tunnels. Take a look at the link I included in my last response. In it, there's a table that showed the results of tests I performed. It was with XP not Win7, but the same *may* apply. I would look in the debug output at the Access-Requests and compare the User-Name attributes for inner and outer tunnels to see if they are *exactly* the same (it's case-sensitive as it is used to construct the challenge/response. I thought of this because my testing produced different results depending upon whether credentials were passed automatically (which is a symptom you described).

The same FR instance works perfectly using the same Aruba controller and user creds if the client OS is XP.

RE: PEAP/MSCHAPv2 failing with Windows 7
I may be misunderstanding you, but FR still auths against a centralized AD (ntlm_auth). I will look into this further though, because it obviously won't honor any DVLAN assignments we have in AD if it's not asking for / expecting them.
