Dave, I'm afraid I can't do that. Since it would be an import from /etc
flat files it won't be just as easy as typing `samba-tool user create
$user`, transferring rfc2037 NIS data (including loginShell, uidNumber,
gidNumber, homeDirectory etc) will be needed as well> >>> Is ActiveDirectory fully retrocompatible with NT4?
