Hi,
I just updated Bind to version 9.9.5 from backports.
On the server I have a test Samba 4 AD with Bind as DNS Server backends.
Samba 4 is from backports too.
After the update, Bind9 is not starting anymore.
From syslog:
named[22249]: Loading 'AD DNS Zone' using driver dlopen
named[22249]: dlz_dlopen: incorrect version 1 should be 2 in '/usr/local/samba/lib/bind9/dlz_bind9.so'
named[22249]: dlz_dlopen of 'AD DNS Zone' failed
