If they grant permissions to you only when you are trying to run a shutdown script, things are safe. They write the shutdown script, it checks what it is shutting down before it takes action.

They protect the script from change. sudo has fairly fine-grained controls on it. An admin could grant run only to certain users on the script. Mid-level management in one department for example.

Is this what you are asking?

SYNOPSIS

       shutdown [--user admin_user][--password admin_password][--host localhost] [--port 4848][--passwordfile filename][--secure|-s]

       shutdown  gracefully brings down the administration server and all the running instances. You must manually start the administration server

       --host                  host name of the machine hosting the administrative instance.

       --port                  administrative port number associated with the administrative host.

       --passwordfile          file containing passwords appropriate for the command (e.g., administrative instance).

       --secure                if true, uses SSL/TLS to communicate with the administrative instance.

       Example 1: Using the shutdown command

       asadmin> shutdown --user admin --password adminadmin --host bluestar --port 4848
       Waiting for admin server to shutdown...
       Admin server has been shutdown
