DNS server no in sync with database?

[Andrew Bartlett]

Kai, 

Can you help me understand what is going on with the internal DNS server
here?

I get different results between ldbsearch and a DNS lookup:

ubuntu at ad-dc-1:~/samba$ host gc._msdcs.samba.example.com 127.0.0.1
Using domain server:
Name: 127.0.0.1
Address: 127.0.0.1#53
Aliases: 

gc._msdcs.samba.example.com has address 10.0.2.6
gc._msdcs.samba.example.com has address 10.0.2.4

While this is what I get when looking via ldbsearch:

ubuntu at ad-dc-1:~/samba$ sudo bin/ldbsearch
-H /var/lib/samba/private/sam.ldb -b
DC=gc._msdcs,DC=samba.example.com,CN=MicrosoftDNS,DC=DomainDnsZones,DC=samba,DC=example,DC=com -s base --show-binary
