The internal DNS doesn't support all types of DSN records at the moment.


        switch (update->rr_type) {
        case DNS_QTYPE_A:
        case DNS_QTYPE_NS:
        case DNS_QTYPE_CNAME:
        case DNS_QTYPE_SOA:
        case DNS_QTYPE_PTR:
        case DNS_QTYPE_MX:
        case DNS_QTYPE_AAAA:
        case DNS_QTYPE_SRV:
        case DNS_QTYPE_TXT:
                DEBUG(0, ("Can't handle updates of type %u yet\n",
                return DNS_ERR(NOT_IMPLEMENTED);

Any idea what application requests that type? Maybe you can capture the
traffic with tcpdump, to get a clue.
