Unable to alter DNS in Samba4

Hi,

 Installed Samba4 as DC in a Docker container. Using Utopic and Samba
4.1.11 as a base.

 The install and provisioning goes smooth - I have also confirmed I can
join using realmd from another client :)

 But, the problem is that you want this containerized, and the ip address
to your DC in your new containers are not valid.

 So, I tried to alter it, but I got errors. I have tried several dns
operations and everything that has to do with update/new records fail.
Queries works nicely. I can add users to the directory, so it seems limited
to dns..

Here is the log: (Old IP is 172.17.0.37, and I want to change it to
172.17.0.41)

root at dc:/# samba-tool dns update 172.17.0.41 openforce.org dc.openforce.org
