I am working on my second Ubuntu 16.04.1LTS running Samba 4.5.0 with
Bind9_DLZ.
I have one machine just like this one. Same hardware, same software
setup. First machine is working fine.
At the moment this (second) machine is not joined to the other (until I
get Bind running.)
I have searched log complaints. Compared settings between the two
machines and despite bind running on the first one, cannot get bind to
run on the second.

I must be overlooking something but, what?
Any suggestions would be greatly appreciated.

Am I giving permission to "/usr/sbin/named" or "/usr/local/samba/lib/bind9/dlz_bind9_10.so" or both? Apparmor is set the same on both machines and first machine works this one (second machine) does not! I thought (could be wrong) that apparmor gives permission to the "name=" file? -- _______________________________ Bob Wooden of Donelson Trophy
