Description Stefan Metzmacher 2016-11-25 10:34:27 UTC 
It is important to handle difference between node_name="w4edom-l4.base"
and node_name="w4edom-l4.base.w4edom-l4.base" with zone_name="w4edom-l4.base".

If someone accedentally added new name as 
"somehost.w4edom-l4.base.w4edom-l4.base", we used to display a recursion
in the Windows dns admin GUI.

Before we got this:

w4edom-l4.base
-> base
  -> w4edom-l4
   -> base
     -> w4edom-l4
        -> base
          -> w4edom-l4
            -> base
              -> w4edom-l4
                -> base
                  -> w4edom-l4
                     -> base
                       -> w4edom-l4
                       ...

Now we get the same as with a Windows server and see a tree like this:

w4edom-l4.base
-> base
  -> w4edom-l4
     -> somehost: A 172.31.111.111
