I have a working DNS server for local domain mydomain.local. I am trying to configure bind9 to work in default configuration, except for this zone, for which I want to forward queries to local DNS server. Here's config I have (ubuntu 14.04):

```
/etc/bind/named.conf.local:

zone "mydomain.local" IN {
    type forward;
    forward only;
    forwarders {
        192.168.1.1;
    };
};

```

But when I try to `nslookup server.mydomain.local` I'm getting following in syslog:

```
error (broken trust chain) resolving 'server.mydomain.local/A/IN': 192.168.1.1#53

```

It is my understanding that this is because of DNSSEC. I don't want to disable DNSSEC globally, but I do want to disable DNSSEC for this very zone. Is it possible?

Please do not suggest using `type slave;` zone. I want to achieve this with forward zone
