Hi Steve,
it's quite likely, that bind running in chroot is the cause of
the problem. You can easily test it by disabling chroot for
named on SuSE systems by editing /etc/sysconfig/named
NAMED_RUN_CHROOTED="no"
If the problem is still there, try running named using strace,
and have a look at all stat()/open() calls concerning dlz_bind9.so.
This should give some hints about missing files/permissions and
may help to narrow down the problem.
Bye,
Marcel

Hi Marcel
Thanks for the confirmation. It narrows down the problem.
I can confirm:
/usr/local/samba/modules/bind9/dlz_bind9.so
is there OK.
However:
hh3:/home/steve # echo $LD_LIBRARY_PATH
hh3:/home/steve # export LD_LIBRARY_PATH=/usr/local/samba/modules/bind9/
hh3:/home/steve # echo $LD_LIBRARY_PATH
/usr/local/samba/modules/bind9/
hh3:/home/steve # rcnamed restart
redirecting to systemctl
Job failed. See system logs and 'systemctl status' for details.
And the file not found error reappears even with the library path set.
In openSUSE named runs chroot (at /var/lib/named). Could that be why it
cannot find the library at the given path? Or a combination of the jail
and the path?
Confused. Any ideas?
Cheers
Steve.
