By doing that, you have nowhere to store ACLS.

The way I look at it, you have Unix permissions (ugo) and everything
else. On Linux you would install the 'acl' package and would then be
able to use setfacl to set ACLs on a dir or file. It is these ACLs that
are being stored (or not) in 'xattr.tdb'. The line in your smb.conf
file was added by the provision because it couldn't find anywhere else
to store the ACLs. Unless your OS as a variant of the 'acl' package, I
cannot recommend using the OS for a Samba AD DC.

This is probably because 'Administrator' is mapped to 'root' on a Samba
