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.
Full output is here: bind9 dyndb crash - Pastebin.com

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)))"
