The iucvconn_on_login script

You can set up the terminal server such that particular users always log in to the iucvconn_on_login script.

An iucvconn_on_login user logs in to Linux™ on the terminal server with a user ID that matches the z/VM® user ID of a target system. After a successful login to the terminal server, the user is immediately prompted to log in to the target system. No action is possible on the terminal server.
