I am going through the lab guide for OES, and when I get to the point to
enable users for samba, I get the following error:

A sambaDomain object was not found. Enabling a user for Samba requires that
a sambaDomain object exist in either the same container as the user object
or in one of that container's hierarchical parents (as defined by the ldap
suffix in smb.conf).

If I go through yast and configure samba server, I get the following error:
cannot create account for user root

Any ideas? The only thing I can find in google is something in russian,
which appears to be the same problem I am having, but my russian is not so
