Hello,

I have successfully set up Samba4 on my network, users and can join, and
everything works apart from dns updates to bind. Whenever a client tries to
make an update, my bind9 server crashes, with the following in the log:

There are also a few other errors I'm not sure how to fix. My bind options
are:

options {
        directory "/var/cache/bind";
        // If there is a firewall between you and nameservers you want
        // to talk to, you may need to fix the firewall to allow multiple
        // ports to talk. See http://www.kb.cert.org/vuls/id/800113
        // If your ISP provided one or more IP addresses for stable
        // nameservers, you probably want to use them as forwarders.
        // Uncomment the following block, and insert the addresses replacing
        // the all-0's placeholder.
         forwarders {
                208.67.222.222;
                208.67.220.220;
         };
        auth-nxdomain no; # conform to RFC1035
        listen-on-v6 { any; };
 tkey-gssapi-keytab "/usr/local/samba/private/dns.keytab";
};

Any help would be greatly appreciated,

Alex
