samba - Apr 2007 - Authenticate against AD/NT4, but use local account?

Hi, all.  I'd like to authenticate a login against AD and/or NT4, but use
a generic local account (so I don't need to maintain local user accounts).
 Since this is an FTP server, doing it "right" isn't really in my
interest
-- I just want to do a simple authentication, then use something akin to
(say) "force user" and "force group" to a local account.

Is this possible/feasible?  Or do I need to have local accounts?

Thanks!

-Ken
