[Samba] PDC and windows xp domain joining - root user does not exist

[Mark Rutherford]

I am trying to set up a samba PDC, and I have followed many FAQ's and 
HOWTO's ive found online.
all seem to be just about the same..
So, I made a config up (at the end of this email)
then I did the following:
added users/machines as such:  (just trying to get it to work, will 
spice it up later)
useradd test$
passwd -l test$
smbpasswd -a -m test
smbpasswd root
(entered a password twice...)

Now... I went to the windows xp machine, changed some registry settings 
(windows xp with service pack 2, BTW.)
then I attempted to join the domain,  entered 'TEST' as the domain, and 
a prompt came up asking me for the username and password required to 
join the domain..
entered root and the root password and... it tells me: 'the specified 
user does not exist'
now, thats damned strange...
so I create another unix user, and then another samba user.. I call this 
user 'test' with a password 'test'
so, I try to use that, and it tells me access denied... so I can 
understand that..
I try to enter root with no password, and it tells me the username or 
password is invalid.. I expected that as well, I guess.
im at a loss. I honestly dont know what to do.
my thing is, at work we are considering switching off of novell in favor 
of samba, so I best get to know it
im off to a rocky start. I hope that someone on list has an idea.
thanks in advance :)


here is my smb.conf, mostly copied from examples:

        logon script = logon.bat
        logon path = \\%N\profiles\%u
        domain logons = Yes
        os level = 255
        preferred master = Yes
        domain master = Yes

[netlogon]
        path = /home/samba/netlogon
        browseable = No

        path = /home/samba/profiles
        read only = No
        create mask = 0700
        directory mask = 0700
        browseable = No

[data]
        path = /home/samba/data
        read only = No
        create mask = 0750
        directory mask = 0750
        guest ok = Yes
