[Samba] Samba 4.7.1 Switching from SAMBA_INTERNAL to BIND_DLZ failed
Hi List!
Im trying to switch from using the samba internal dns to bind.
Im running a self-compiled samba 4.7.1 pair of DCs on Centos 7.2.
After following the steps in the wiki, named refuses to start with this error:

It looks like the wrong file is being found, it should be here: /usr/local/samba/lib/private/libreplace-samba4.so Also, why are there '7' zones ? Rowland

Hi Rowland!
Yes there are samba packages installed:
[root at testdc1 ~]# rpm -qa | grep samba
samba-client-libs-4.6.2-11.el7_4.x86_64
samba-winbind-modules-4.6.2-11.el7_4.x86_64
samba-common-libs-4.6.2-11.el7_4.x86_64
samba-common-4.6.2-11.el7_4.noarch
samba-common-tools-4.6.2-11.el7_4.x86_64
samba-libs-4.6.2-11.el7_4.x86_64
And there are seven zones because of /etc/named.rfc1912.zones:
// Provided by Red Hat caching-nameserver package
//
// ISC BIND named zone configuration for zones recommended by
// RFC 1912 section 4.1 : localhost TLDs and address zones
// and
http://www.ietf.org/internet-drafts/draft-ietf-dnsop-default-local-zones-02.txt
// (c)2007 R W Franks
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//
zone "localhost.localdomain" IN {
type master;
file "named.localhost";
allow-update { none; };
};
//zone "localhost" IN {
// type master;
// file "named.localhost";
// allow-update { none; };
//};
zone
"1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa"
IN {
type master;
file "named.loopback";
allow-update { none; };
};
zone "1.0.0.127.in-addr.arpa" IN {
type master;
file "named.loopback";
allow-update { none; };
};
zone "0.in-addr.arpa" IN {
type master;
file "named.empty";
allow-update { none; };
};
And the localhost zones from the wiki.
