Not that it affects the above situation, but I thought the shadow tools 
in  Redhat Enterprise Server 4 doesn't allow "$" in any user name.  I 
end up adding the machine accounts to the unix side without a $, then 
editing /etc/passwd and /etc/shadow by hand and adding the $, which when 
I then do smbpasswd -m machinename, it does work.   I think it's purely 
a problem with the Redhat Enterprise AS 4 servers, since Fedora Core 3, 
which RHAS4 is based on, allows it just fine, which works well since it 
allows the standard samba "add machine script = " to work.  Any 
suggestions or workarounds?
