Samba needs its own password file because Windows and UNIX use
fundamentally different and incompatible methods of password encryption.
You can't get from either password hash back to a clear password, so you
can't compare them. If you make the registry change that tells Windows
to use unencrypted passwords, then Samba can use the ordinary system
passwords. I don't think you can do that with domain security, though.

You shouldn't need one. It may still exist, of course.
