We also have a PowerDNS server which is acting as a master for domains configured as NATIVE and it's also acting as a slave for the domains added in DirectAdmin.</div><div>This is done by configuring the IP address of the DirectAdmin server in the supermasters table. All workin as expected.</div><div><br data-mce-bogus="1"></div><div>Now, we noticed that if we configure "domain.com" as a NATIVE domain in PowerDNS it is still possible to configure "sub.domain.com" in DirectAdmin and powerdns will accept the subzone from the supermaster.</div><div>This way users on our DirectAdmin server can break configurations for domains configured as NATIVE.</div><div><br data-mce-bogus="1"></div><div>We need a way for PowerDNS to reject all *.domain.com subzones from any supermaster if the main domain is configured as NATIVE.</div><div><br data-mce-bogus="1"></div><div>Is there a way to do this?</div><div><br data-mce-bogus="1"></div><div>Thanks</div><div><br data-mce-bogus="1"></div><div>Sander</div></div></body></html>
