There are two schools of thought here, you can give administrator a
uidNumber, but this would turn Administrator into just another Unix user
and as such wouldn't be able to do anything that is required. You can
work around this by using members of Domain Admins and giving the group
the required permissions on Unix machines.
The other way is the way that Samba does it, the AD user 'Administrator'
is mapped to the Unix user 'root' this allows 'Administrator' to change
Unix settings from windows. You do not actually have to use 'root' to
change anything on a Unix machine, you can change the settings from a
windows machine as 'Administrator', this is the way I would suggest
The same goes for 'Domain Users', on a DC, this group is mapped to the
Unix group 'users'
