An NIS+ client can be connected to the Internet using the name service switch. Workstations, if they are also DNS clients, can have their name service switch configuration files set to search for information in DNS zone files--in addition to NIS+ tables or NIS maps.
Configure each client's /etc/nsswitch.conf and /etc/resolv.conf files properly. The /etc/nsswitch.conf file is the client's name service switch configuration file. The /etc/resolv.conf lists the IP addresses of the client's DNS servers; it is described in Solaris Naming Setup and Configuration Guide.
Test the joint operation of NIS+ with DNS.
Verify that requests for information can pass between the namespaces without difficulty.
Use the nispopulate script to transfer information from NIS to NIS+. To transfer data from NIS+ to NIS, run nisaddent -d and then ypmake. (See the man pages for more information.) Use scripts to automate this process. Establish policies for keeping tables synchronized, particularly the hosts and passwd tables. Test the tools used to maintain consistency between the NIS and NIS+ environments. Decide when to make the NIS+ tables the real source of information.
