[Samba] Restricting Sites and services in Samba4 DC

[Prema]

Hi all,

I want to restrict the Samba4 DC to take the replication from only one
server among 30 servers in my network. So i joined the samba server with
--site option

samba-tool domain join test.local DC -Usuperadmin --site=win-pdc
--realm=test.local

But after joining the Sites and services entry for Samba DC automatically
generated all the 30 servers.
Deleting all the entries and manually creating only one server is of no
use. With in few minutes all the servers are getting generated again.
How to solve this issue in samba4.
