[Samba] Failover

[Chan Min Wai]

Let make some assumption.
For Both DC1 and DC2:
1. Have DNS server (and also in NS in all Domain that you serve)
2. Have KDC running (auto by samba AD DC)
3. replicated successfully (check with samba-tools drs showrepl, there
shouldn't be any number on xxx "xxx consecutive failure(s).")
---- it should always be 0 if the AD DC are not high in load or disconnected
4. Windows Client have both DNS server on their DNS list

Than both DC are running in load balance and fail over mode

Enjoy :)
