Enable RACF-DELEGATED (Nested ACEE) Support for SERVAUTH EZB.PORTACCESS SAF calls

Need SERVAUTH PORT access checks to support RACF-DELEGATED feature so that access to TCP port 20 (FTP's active data port) can be limited to only the FTP daemon's user ID using the SAF keyword on the PORT statement in the TCPIP profile. This support would also allow any other port to leverage RACF-DELEGATED support as long as the application that owns the port is using nested ACEEs and RACROUTE REQUEST=FASTAUTH.

    This Idea is unlikely to be given high enough priority to be placed into product plan. However, there is an alternative solution:

    Access to bind to the FTP active data port (TCP port 20) can be controlled using SAF program control on the SAF profile that protects port 20. Specifically, the program names ?FTPD? and ?FTPDNS? must be listed on the WHEN PROGRAM clause for the SERVAUTH class EZB.PORTACCESS.<sysname>.<stackname>.<port_safame> profile that protects TCP port 20. This will limit access to the z/OS FTP server program.

    To protect access to z/OS FTP server passive data ports, use the AUTHPORT parameter of the PORTRANGE statement for the FTP server?s PASSIVEDATAPORTS range to ensure that only the z/OS FTP program can access those ports.
