[Samba] DNS question

[L.P.H. van Belle]

Hai, 

Post me for both DC the debug output of: 
https://raw.githubusercontent.com/thctlo/samba4/master/samba-collect-debug-info.sh 

Anynomize it where needed. 

The problem your are having is due to.. "Something it not right."
But what? That is not impossible to tell because we see any config.. 
And why? Because this setup should work fine. We know it should work fine. 

Greetz, 

Louis
