Defining Users
This chapter provides in-depth information on defining users for z/VM® systems.
All users defined to CP must also be defined to RACF®. Users who are not defined
to RACF cannot use the system
or access any of its resources. It is possible to define users to RACF who are not defined to CP
in the user directory. While they do not have a virtual machine of
their own, these users can access system resources from another system
using FTP, APPC, or other remote resource access protocols. When authorized,
they can also logon to other users using LOGON BY.
Note: See Controlling OpenExtensions and BFS Security for information about RACF security at the Portable Operating System
Interface (POSIX) 1003.1 level.
