samba - Jul 2014 - how to fix dns queries

Hello,

just having a successful migration from s3 to samba4 running the
sernet-samba-package 4.1.8 with bind-9-8.2! (Thanks for the wiki-docs! )

Now, i encounter the following issue:

Searching  for all the registry entries that contain the broken records
using:

samba-tool dns query SERVER DOMAIN @ ALL

There are registries like:

 Name=WORKSTATION
CNF:ed567568-5230-4796-ba53-935e3ade3013, Records=1, Children=0
    A: x.x.x.x (flags=f0, serial=1925, ttl=900)


What are these CNF-Records? What is to do with them?

Thanks for help.

Chris
