ldap2dns is a program to create DNS (Domain Name Service) records directly from a LDAP directory. It can and should be be used to replace the secondary name-server by a second primary one.
ldap2dns reduces all kind of administration overhead: No more flat file editing, no more zone file editing. After having installed ldap2dns, the administrator only has to access the LDAP directory.
Optionally she can add access control for each zone, create a GUI and add all other kind of zone and resource record information without interfering with the DNS server.
