Setting Up the System So a User Does Not Have to Enter a User ID and Password

At security level 30 and below, signing on by pressing the Enter key without a user ID and password is possible with certain subsystem descriptions. At security level 40 and higher, the system stops any attempt to sign on without a user ID and password.

After changing your security level to 20 or higher, signing on without a user ID and password is not allowed in the subsystems shipped by IBM®. However, defining a subsystem and job description combination that allows default sign on is possible and represents a security exposure. When the system routes an interactive job, it looks at the workstation entry in the subsystem description for a job description. If the job description specifies USER(*REQ), the user must enter a valid user ID and password at the sign-on display. If the job description specifies a user profile in the USER field, anyone can press the Enter key and sign on as that user.
