Yes I did.

here is my /etc/named.conf

[root@sambaserver ~]# cat /etc/named.conf
//
// named.conf

options {
        listen-on port 53 { 127.0.0.1; 192.168.122.100; };
## listen-on-v6 port 53 { ::1; };

        allow-query { localhost; 192.168.122.0/24; };
        recursion yes;
        forwarders { 192.168.122.1; };

        tkey-domain "QUINOX.BE";
};

};

zone "." IN {
        type hint;
        file "named.ca";
};

include "/etc/named.rfc1912.zones";

>> Hi all,
>>
>> I've setup samba4 according to the samba4 wiki on centOS 5.4 in KVM.
>> This went without any problems. I only had to install a higher version
>> of
>> bind to 9.6.x because Centos bind in repo will install version 9.3.x.
>> I've used the Fedora12 source rpms for this to build bind 9.6.x on
>> Centos
>> 5.4.
>>
>> Then I configured bind according to the samba wiki
>> (http://wiki.samba.org/index.php/Samba4/DNS)
>>
>> I did all the check in the wiki to see if bind is working. All tests
>> passed.
>> But in my logs a got the messages "The working directory is not
>> writable".
>> I changed the owner on /var/named to the group named, which solved that
>> problem.
>>
>> Then i installed Win7 virtual in KVM and joined the domain. I can login,
>> create users via dsa.msc tool on windows and see them in wbinfo -u on
>> the
>> samba4 domain controller. All looks right, except for my ddns. The zone
>> could not be updated with the new win7 machine. The win7 machine has a
>> fixed ip-address.
>>
>> I checked all the howto again and again, but couldn't find a thing which
>> could cause this. The error I see in my log is:
>>
>> Aug 11 09:34:46 sambaserver named[2281]: client 192.168.122.150#60058:
>> query 'roland.quinox.be/SOA/IN' denied
>>
>> Is this a permission problem? I check and the group 'named' has write
>> access to my zone file. (the user 'named' is member of the group
>> 'named')
>>
>> This is the only issue I have with my samba4 installation and I really
>> want to solve this issue.

>> If you need more information or configurations, i can post them.
