Question:

How to have a user in a zone but not allow access to the server?

Answer:

Assign the user to the predefined role called "Listed role", which is available by default in every zone. The Listed role makes a user profile visible in a zone but does not grant any type of access rights, PAM rights, or command rights. This is a specialized role that can be used when a user profile must exist for computers in a zone, but no local or remote access should be granted .

For more information about the predefined access right / role. please refer the Administrator’s Guide for Linux and UNIX.
