Daniele, I have now set up a second DC and joined it to AD. I have seen
that replication of ForestDnsZones and DomainDnsZones in
private/sam.ldb.d is working, but I am missing the private/dns part.
samba_upgradedns gave the same error as Justin has observed. best

>> Hallo Andreas, for me (I've just demoted the
secondary DC and than reinstalled and re-joined it to the domain) I
don't see DNS zones in private/sam.ldb.d. I guess that for you,
samba-tool drs showrepl shows also the DNS zones in the INBOUND and
OUTBOUND NEIGHBORS isn't it? Daniele.

Hello Daniele, 

yes I can confirm, that I see
inbound replication on second DC for ForestDnsZones and DomainDnsZones
coming from first DC. I do see any sign of either inbound or outbound
replication on the first DC though.
