hi, from a 2 second inspection on the error I can see one major difference - you are logging in with lower case, not upper case.
the ntlm_auth is failing because the challenge-response for this user is not working. i suggest you check out the 'case sensitive' parts of your radiusd config! alan - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
