The differences between NIS-compatible and standard NIS+ servers in subdomains are the same as they are for servers in the root domain (see Standard Configuration and NIS-Compatible NIS+ Configuration Procedures).
The NIS+ daemon for each server in an NIS-compatible domain should have been started with the -Y option, as instructed in Chapter 7, Configuring NIS+ Servers. An NIS-compatible domain also requires its tables to provide read rights for the nobody class, which allows NIS clients to access the information stored in them. This is accomplished with the -Y option to the nissetup command, shown in Step 4. (The standard NIS+ domain version uses the same command but without the -Y option, so it is described in the same step.)
Here is a summary of the entire configuration process:
Log in to the domain's master server.
Name the domain's administrative group.
Create the domain's directory and designate its servers.
Create the domain's subdirectories and tables.
Create the domain's admin group.
Assign full group access rights to the directory object.
Add the servers to the domain's admin group.
Add credentials for other administrators.
Add the administrators to the domain's admin group.
