[Samba] trouble joining domain

[Jim Wharton]

I have added a machine account to /etc/passwd named luna$ and in smbpasswd
named luna. When I attempt to join my Win2K box to the domain, I get this
error.

The following error occured attempting to join the domain:

The account used is a computer account. Use your global user account or
local user account to access this server.

I am using openldap if that makes any difference.
