This recipe is useful in situations where a particular user requires information on the status of certain hosts and services but should not be allowed to view others. This is a setup that can't be managed with the directives in cgi.cfg.

As a simple example, on a given monitoring server, we might have two hosts configured as follows:

    host_name  sparta.example.net
    alias      sparta
    address    192.0.2.21
    contacts   nagiosadmin
}
define host {
    use        linux-server
    host_name  athens.example.net
    alias      athens
    address    192.0.2.22
    contacts   nagiosadmin
}

We might like to add a new user athensadmin with permissions to view the status of and run commands on the athens.example.net host and its services but not the sparta.example.net host or its...
