For normal readers you kn ow already my setup, but for those new here, I
have a Samba4 PDC and two BDCs one a samba4 and the other a W2k8 R2 machine.
Yesterday we had problems with our upstream service provider and my PDC
(Backend BIND 9 DLZ) went down for some hours, as you might guess my
whole AD was down due to the fact that the main DNS was down.
I would like youi to point me or tell me how do I create a fail-over or
high availability system so that when one of the DCs is down the other
takes over Auth tasks and obviously DNS.
I've thought a solution would be to make a slave BIND DNS on another
slaver and replicate the Samba Zone and add aappropriate NS and A
records to the main zone so that clients can query another DNS for the
zone and not fail as I faced yesterday. This is a production environment
scenario and I have many servers authenticating users against the samba
server so if this fails everything else does.
I'd really appreciate your advise here.
