[Samba] Why is this failing???

[Stephen C. Biggs]

Trying to join a SAMBA domain from Win2K SP3.  It fails the password 
check for 'root' as per the log entries below, then it defaults to 
'nobody' which then tries to run 'useradd' to add the windows machine 
name, failing, of course.

I tried this both with lanman auth = yes and no...  encrypt password = 
yes

I can connect to Samba shares just fine from windows using another user 
that isn't privileged on Linux, even if the NT4 MD5 password fails (why?) 
but the Lanman password works for the current user.

I want to join to the Samba domain.  Why isn't this working?
