New Application Authorization

Service

A DCE application server on OS/390 can

use

DCE

security

services

for

a

control to resources that

are owned

by

the

application

server. As

a

the application developer can use

RACF

for

access

control

for

the

se

that are managed by the application server.

Consider

that application

servers

that

use

DCE

services

exclusively

on

the most portable to platforms that support

DCE. If

portability

is

no

concern and the application developer wishes to centralize access co

information in RACF, the application

developer

can consider

using

the

auth_check_resource_np service.

Through OS/390 OpenEdition MVS, a new a callable service

auth_check_resource_np (BPX1ACK) enables application servers to invoke R authorization services. This callable service is also supported by th library through the __check_resource_auth_np() function call. This ser application servers to perform authorization requests for resources t to RACF general resource classes.

Changes to the Class Descriptor Table

The maximum length of profile names has changed for the following clas

ŸINFOMAN

ŸGINFOMAN

ŸJCICSJCT

ŸKCICSJCT

This change might require changes to customer code which uses these

ŸRACROUTE REQUEST=FASTAUTH

Ÿ RACROUTE	REQUEST=AUTH,	DEFINE, or EXTRACT, if the ENTITY keyword
is used	instead of	ENTITYX

IBM products should not need changes, because their usage of these compatible with this change.
