I have a useradd modified to allow this, and also to be called from samba,
so that a machine can add itselfs to the domain if the admins doing
it knows the root passwd (mandatory for windows 2000). I added to my smb.conf:
   add user script = /usr/local/adm/smb_useradd -d /nonexistent -c "%m account" -p "*************" %m$
    domain admin group = root

I also changed it to read be called smb_useradd and read
/usr/local/adm/smb_useradd.conf as config file.
