You can also enable logging by putting this snippet into your
named.conf:

----
logging {
        channel ldap {
                file "data/ldap.log";
                severity debug 9;
        };
        category database {
                ldap;
        };
};
----

And restarting named.

The logs should then be written to /var/named/data/ldap.log
