[Fedora-directory-users] Administration domain

Hi, I want to deploy a FDS service in a different geography sites (sharing the same data), and i have a problem with administration (console administration of administration server). I've installed a FDS server in all sites with the same information (by replication) and i want try administrate with a local console (local access to fds in each server), and furthermore, administrate all fds server(access to all server through console) in one central site. Administration domain are the solution? and why? or subscribe all administration server to central server? thanks,
