Before proceeding, make sure that
The /etc/passwd file on the root master server must contain an entry for you and every other administrator whose credentials will be added to the root domain in this configuration process.
If the server will operate in NIS-compatibility mode and support DNS forwarding for Solaris 1.x release clients, it must have a properly configured /etc/resolv.conf file as described in "The Resolver".
The server must have a unique machine name that does duplicate all user IDs.
The server must have a machine name that does not contain any dots. For example, a machine named sales.alpha is not allowed. A machine named sales-alpha is allowed.
