[RADIATOR] Problem rewriting inner username with PEAP-MSCHAPV2

Hi Hugh,

Manual 4.3.1 section 5.18.57 (page 82 of 346)

UsernameMatchesWithoutRealm does not list "AuthBy LSA"

I have added the line anyway, and the part of the debug that used to say
Tue Dec 23 11:54:51 2008: DEBUG: Radius::AuthLSA looks for match with mike at utas.edu.au [anonymous]
Tue Dec 23 11:54:51 2008: DEBUG: Radius::AuthLSA ACCEPT: : mike at utas.edu.au [anonymous]
Tue Dec 23 11:54:52 2008: WARNING: Could not LogonUserNetworkMSCHAP (V2): 3221225581, 0, Logon failure: unknown user name or bad password.

NOW says (utas.edu.au stripped)

Wed Dec 24 11:05:08 2008: DEBUG: Radius::AuthLSA looks for match with mike [anonymous]
Wed Dec 24 11:05:08 2008: DEBUG: Radius::AuthLSA ACCEPT: : mike [anonymous]
Wed Dec 24 11:05:08 2008: WARNING: Could not LogonUserNetworkMSCHAP (V2): 3221225581, 0, Logon failure: unknown user name or bad password.

But still no ACCEPT unless I don't pass in the @utas.edu.au as part of the username in the first place (shown below).

Wed Dec 24 11:20:39 2008: DEBUG: Radius::AuthLSA looks for match with mike [anonymous]
Wed Dec 24 11:20:39 2008: DEBUG: Radius::AuthLSA ACCEPT: : mike [anonymous]
Wed Dec 24 11:20:39 2008: DEBUG: EAP result: 3, EAP MSCHAP V2 Challenge: Success
Wed Dec 24 11:20:39 2008: DEBUG: AuthBy LSA result: CHALLENGE, EAP MSCHAP V2 Challenge: Success

Cheers, Michael

PS. I think I saw Windows7 Beta using forward-slashes not back-slashes when passing in DOMAIN\user-name (viz DOMAIN/user-name). Something I'll check again later. Don't know it this will break anything, but not part of this current issue anyway.

Hello Matti, Hello Michael -

Correct - rather than use a RewriteUsername, you should use  
UsernameMatchesWithoutRealm in the inner AuthBy LSA clause.

regards

Hugh
