Samba Domain Members have, like Windows, some built-in accounts/groups,
which require the mappings. E. g.
BUILTIN\Print Operators
BUILTIN\Account Operators
BUILTIN\Backup Operators
BUILTIN\Server Operators

You don't need to map Administrator to root. If your granted
SeDiskOperatorPrivilege to you Administrator account or a group, it
belongs to, it should be enough to edit the permissions. But some do
that mapping and as more information about your configuration we have,
as easier it would be to find out, what's wrong. :-)

But if you have a 'username map' entry, you have to add and enable the
account with smbpasswd -a/-e.

It's still on my to-do list, to write the documentation for the
different Idmap backends. But in the meantime, have a look at the
manpage of 'idmap_rid'. The usage is like for the rfc2307 backend.
