The RACROUTE REQUEST=FASTAUTH macro uses the profiles constructed in a data space by the RACROUTE REQUEST=LIST macro, and under certain circumstances by the SETROPTS RACLIST command, to perform authorization checking. REQUEST=FASTAUTH has exits that enable you to make additional security checks, or to instruct RACROUTE REQUEST=FASTAUTH to accept or fail the request to access a resource.

The RACROUTE REQUEST=FASTAUTH macro has two preprocessing and two postprocessing exits. The invocation of these exits is determined by the circumstances involved in the invocation of the macro. These circumstances include whether the macro is invoked in cross-memory, and which operands are specified. See the RACROUTE REQUEST=FASTAUTH exit information in z/OS Security Server RACF System Programmer's Guide for details.
