| CL/SuperSession requires a started task that will be restricted to certain resources, datasets, and other system functions. Defining the started task as a userid to the system ACP allows the ACP to control the access and authorized users that require these capabilities. Failure to properly control these capabilities could compromise the operating system environment, ACP, and customer data. | ||||
