There are two schools of thought here, you can add a uidNumber to 
'Administrator' but if you do this, you will have to change ownership 
from 'root'  to 'Administrator' of anything that needs to be changed 
from windows. You can instead, map 'Administrator' to 'root' on a member 
server with a line in smb.conf: 'username map = /etc/samba/user.map' and 
the map file '/etc/samba/user.map' containing:

!root = DOMAIN\Administrator DOMAIN\administrator Administrator 

This is done automatically on an AD DC without the map file.

You pay your money and take your choice :-)
