So, if you are an administrator who has deployed mod_ntlm_winbind, you
may not wish to lock out clients running older mozilla, or lynx, or ...

So, you will want to accept as a last option, a basic authentication
request, and submit this to your DC for verification.  We have all the
hooks for this, I just didn't add them back to mod_ntlm_winbindd when I
ported it to ntlm_auth.
