TCP/IP port reservation

If you use the EZB.PORTACCESS.<sysname>.<tcpname>.<resname> security profile in the SERVAUTH class to control bind permissions to a given port, it is the client's user ID instead of the RSED daemon server ID that does the bind to the ports defined in _RSE_PORTRANGE. Consult your TCP/IP administrator to learn whether the ports in _RSE_PORTRANGE are protected and defined with the SAF keyword or not.
