[Samba] pad length mismatch error message

[L.P.H. van Belle]

Well, 

If you running with bind9_DLZ, you also should enable it.  

Based on what i see below, its not enable, you installed it your not done yet. ;-) 
Verify the settings ( debianize the paths ) 
https://wiki.samba.org/index.php/BIND9_DLZ_DNS_Back_End 

Then then its all done, reboot the server.
Run this script, anonimized it and post the content to the list. 

Then i know all i want to know.
