Panvalet Security Exit

MFA supports a customized user exit (MFAPVXIT) that enables you to implement member-level security within your Panvalet repositories. This user exit is required because security is not available via RACF, and a proprietary Panvalet exit (PSPILXIT) is only available under TSO dialogs.

MFAPVXIT is automatically invoked to approve access rights for all Panvalet activity: import, export, and directory requests. A sample exit and test harness is provided within the .CNTL file shipped with the MFA product libraries:

MFA provides the user ID, member name, and Panvalet master file name to MFAPVXIT, and interprets a return code of zero to mean that access is permitted. Any other return code results in access being denied. This means that the MFAPVXIT can create a directory filter based on the access rights of the individual or his department. The algorithm is entirely up to the site, and will be based on table-driven data compiled into the exit. The sample exit demonstrates how naming conventions, or tables of authorized users can be used to accomplish this.
