You can add DNS forwarding capabilities to an NIS+ daemon running in NIS-compatibility mode by adding the -B option to rpc.nisd:
rpc.nisd -Y -B |
If the server is rebooted, the daemon will not restart in DNS-forwarding NIS-compatibility mode unless you also uncomment the line that contains EMULYP=-Y in the server's /etc/init.d/rpc file and change it to:
EMULYP -Y -B |
