It's slightly more involved. First you have to make sure that DNS
partitions are getting replicated between two DCs. If the DNS
partitions are not replicated correctly you won't be able to run DNS
server on secondary DC. Next step is to use samba_upgradedns script to
"fix" the provision on secondary DC and to create the files required
by DLZ backend.

The main issue reported by few users is that the replication fails at
times and I have not yet been able to figure out the root cause of
this. So if you notice issues with replication, let me know.
