  The only *other* choice is that the client is doing MS-CHAP calculations wrong.  FreeRADIUS just packages that up and sends it to ntlm_auth.  So if the calculations are wrong, then ntlm_auth will return "fail", even when ntlm_auth and samba are configured correctly.

  That can be tested by doing a test without ntlm_auth, and a locally configured password.  If that works, then the client is fine.  And, the problem isn't FreeRADIUS.  Because FreeRADIUS can authenticate users just fine.
