I'm trying to use bind9 and the dyndb-ldap plugin with Olpenldap on Debian as a standalone DNS server. Any configuration where named can successfully find the top of the DNS configuration branch, named crashes.
Per the instructions, I'm posting here first.

The config is
dyndb myLDAP "/usr/lib/x86_64-linux-gnu/bind/ldap.so" {
uri "ldap://localhost:389";
base "idnsServerId=zed2,dc=mynicehome,dc=home";
auth_method "simple";
bind_dn "cn=someUser,dc=mynicehome,dc=home";
password "somePwd";
server_id "zed";
reconnect_interval 10;
verbose_checks true;
};
The only other config is to move the listeners off UDP 53
listen-on port 5353 {127.0.0.1;192.168.15.5;};
listen-on-v6 port 5353 {any;};
max-cache-size 10%;

A search works.
ldapsearch -x -b 'cn=dns,dc=mynicehome,dc=home' "(|(objectClass=idnsConfigObject)(&(objectClass=idnsServerConfigObject)(idnsServerId=zed)))"
