Considerations for Use
If security administrator status is authorized for the system, then a security administrator usercode is required to execute this command.
The MU command is not allowed on a password-generating system.
If the model entry contains a password, then a password must be specified when the usercode is created using the MU system command.
A valid USERDATAFILE must be present; otherwise, the system responds with a REQUEST DENIED message. The MU action is subject to regulation by the MU model entry in SYSTEM/USERDATAFILE. This entry can disallow either the entire MU command or the PRIVILEGED option of the command. See the MCP Security Overview and Implementation Guide and the Security Developer’s Kit (SDK) for more information on the USERDATAFILE.
