I just cloned and built the latest 2.1.10 to do some testing.  I did a 
PEAP-MSCHAPv2 authentication, with bad credentials, using eapol_test.  What I 
found seems to indicate the problem I was referring to still exists in 2.1.10 
(probably because I wasn't clear enough in describing the issue).  

It seems that after ntlm_auth fails, it sends the EAP failure via an 
Access-Challenge.  Then, after it receives the response in the next 
Access-Request, it sends Access-Reject.  This is how it behaved prior to 2.1.9 
also (this is what I meant by "extra round trip" in a previous post).  The 
problem is that any information stored in an attribute, after the ntlm_auth 
failure, will not survive the subsequent Access-Challenge, Access-Request.  I 
can post the debug output if you'd like to see it.

When I originally discovered this, I suggested storing the ntlm_auth output in 
the eap handler so it could be saved in Module-Failure-Message when the 
response to the EAP failure is received.  Is there a better approach?  If you 
tell me your preference, I'd be willing to create a patch..

Thanks for your time Alan.
