Repeat the preceding client-initiation procedure on as many machines as you like. To initiate clients for another domain, repeat the procedure but change the domain and master server names appropriately.
The sample NIS+ domain described in this chapter assumes that you will initialize four clients in the doc.com. domain. You are then going to configure two of the clients as non-root NIS+ servers and a third client as a root replica of the root master server of the doc.com. domain.
You always have to make a system into a client of the parent domain before you can make the same system a server of any type.
