Using the AUTHUSER MIM File

Another, more general form of authorization also operates under CA MIM. The AUTHUSER MIM file can be used to control all commands, including cross-system commands that are issued by any user.

By default, AUTHUSER MIM permits all z/VM users to send commands to CA MIM. It is possible, however, to restrict access attempts to a limited set of users. In most cases, it is not necessary or recommended to make the AUTHUSER MIM file very restrictive.

The AUTHUSER MIM file controls access to the command interface for all CA MIM functions, including CA MIC cross-system commands. Other functions include commands sent to CA MIA Tape Sharing (CA MIA) for z/OS and CA MIM Resource Sharing (CA MIM) for z/OS.

For more information about the AUTHUSER MIM file, see the chapter "Customizing" in the CA MIM Resource Sharing for z/VM Programming Guide.
