I have searched through the mailing list and Google for the resolution to this, and I have found quite a bit of information, but I have not yet found the solution to my problem. I am trying to properly configure a FreeRADIUS version 3.0.9 server to authenticate wireless users using PEAP and MSCHAPv2 against a OpenLDAP version 2.4.39. I can authenticate both users that I will be discussing directly against the LDAP server correctly (using "ldapsearch"). However, only one of them work via the wireless connection. I have attached 2 files: - debi-debug.txt: the failing account full debug of radiusd -x - alex-debug.txt: the working account full debug of radiusd -x These dubugs were gathered by attempting to authenticate the same Windows 7 laptop to the 802.1x wireless network. Working laptop, working network, different outcomes with two accounts that both work when authenticated with ldapsearch. When I run the debi-debug.txt text through the web debugger, I get the following lines in red: mschap: ERROR: FAILED: No NT/LM-Password. Cannot perform authentication mschap: ERROR: MS-CHAP2-Response is incorrect [mschap] = reject } # Auth-Type MS-CHAP = reject MSCHAP-Error: ?E=691 R=1 Could not parse new challenge from MS-CHAP-Error: 2 ERROR: MSCHAP Failure This is what I have been searching for, but I can't find any real reason that it works for the alex account but not the debi account. I can provide whatever is needed to find the problem here, I just don't know what will be helpful. TIA! Alex
