We use our secondary nameserver for multiple DirectAdmin servers. Most of the time this goes without problems.
Problems do occur however when domain.com is already added at DirectAdmin server A and somebody also adds domain.com at DirectAdmin server B. This should not be allowed as the secondary nameserver can't serve the same domain twice.
Is there anything we can do to prevent adding a domain that is already served on the secondary (non DirectAdmin) nameserver?
