Yes I do. Centos 5.5

I do have those two lines in my /etc/sytsconfig/named file.

btw. This evening I've installed a new virtual machine and used your howto
for the installation of samba4 and DNS.

Unfortunatly...I have the same problem again:
Aug 12 20:58:34 localhost named[28804]: client 192.168.122.150#54473:
update 'quinox.nl/IN' denied

This is driving me crazy.I even chmod -R 777 /usr/local/samba/private/dns
but also that didn't help.

I have installed bind-9.6.2-5.

regards,

Roland de Lepper
