Alle incorrect rights, and thats your problem.
Bind cant write.


Your folder 
/var/lib/samba/private/dns/sam.ldb.d/ 
has 750 set, should be 770 
and root:root, should be root:bind. 

please check, from this point, below is what you want. 
/var/lib/samba/private/dns
drwxrwx---  3 root bind    4096 Jun  1 09:41 dns

so do a chgrp bind on all files and folders.. 
and make sure you have 660 set on the files. 
and that should fix it. 

Greetz, 

Louis
