Hi,
I am no expert on bind, but I install bind-9.6.1-13.P2.fc12.i686 and
bind-sdb-9.6.1-13.P2.fc12.i686 on Fedora 12 x86 with a mysql configuration
example from bind-dlz.sourceforge.net.
If I do: "dig @192.168.0.82 test24.com any", I get:
; <<>> DiG 9.6.1-P2-RedHat-9.6.1-7.P2.fc11 <<>> @192.168.0.82 test24.com any;

But if I do the same for a real domain on a bind box without dlz, I get:

Why are the additional and authority sections missing when using dlz?
