I don't think this applies to bind 4.9 but I just struggled with
this same issue myself. The problem I was having was that I needed
to turn off forwarders in my master zone.

	zone "wmi.com" {
        	type master;
        	allow-update {
            	key DHCP_UPDATER;
            	    127.0.0.1;
            	    192.168.1.9;
                    192.168.1.18;
        };
        file "wmi.com";
        forwarders {};
};

It seems forwarders override delegations. At some point I'll break down
and
turn forwarders off globally.
