Hm, thinking about this a little more, if you're still trying to log in
with domain users, your best bet is probably option 3 in the Users
Guide.  Since option 2 is using the Local Security Authority (LSA), it's
not going to get better at authenticating domain users than the default
mode unless the user you run the service as can authenticate domain
users.  So in this respect, it's the same thing as the default option
(the first option in the Users Guide).  Option 3 authenticates with the
password though so it should be much more like normal ssh password
authentication.  Give it a try and let us know if my thought experiment
works in the real world. :-)
