  That is an error returned by Active Directory, or Samba.  Not FreeRADIUS.

  Try running the ntlm_auth command manually.  That's why it's printed
in the debug output.  So you can cut & paste it into a terminal.

  You'll have to manually piece together the command line, but that's
just a matter of a few minutes of editing.

  If the command fails when you runn it manually, then it isn't a
FreeRADIUS problem.
