[Samba] Cant find uid=0

[Philip Burrow]

Im having a problem adding machines to a domain. All has been fine until
today. This is the output when I try to add a machine (WinXP). It appears to
be looking for a root user in my LDAP directory but isnt finding it (because
there isnt a user 'root' there). User 'Administrator' exists.

Must there be an instance of 'root' in Samba LDAP backends? I've ploughed
through the idealx HOWTO for this, but Messrs Lemaire don't explicitly
create a root user. Can someone help?

then further on it'll say:

  Couldn't find user 'root' in passdb.
