Chapter 6. Customization Considerations

This chapter identifies customization considerations for RACF.

Programmer's Guide.

Customer Additions to the CDT

Installations must verify that classes	they have added to the class
(CDT) do not conflict with new classes	shipped with RACF. If duplicate
entries are detected, the following	error messages are issued at

ŸFor a duplicate router table entry, RACF issues this message and processing:ICH527I RACF DETECTED AN ERROR IN THE INSTALLATION ROUTER

TABLE, ENTRY class_name, ERROR CODE 1.

ŸFor a duplicate CDT entry, RACF issues this message and enters fa

If a conflict in class names occurs, you must delete the profiles installation-defined class with the conflicting name, delete the CDT ent class, add a CDT entry with a different name, and redefine the pr

Do not assemble the user-defined CDT (ICHRRCDE) on OS/390 Release 2 a attempt to use it on a system running RACF at a lower level than RACF

Exit Processing

Installation-written exits might be affected by new function introduce Release 2 Security Server (RACF).

Effects of OS/390 OpenEdition DCE	Support on	ICHRCX01, ICHRCX02,
and IRRSXT00
OS/390 OpenEdition	DCE support	can affect:

Ÿ The RACROUTE REQUEST=AUTH preprocessing and processing exits

ŸThe IRRSXT00 installation exit

RACROUTE REQUEST=AUTH Preprocessing			and
Postprocessing		Exits
RACF	support	for OS/390 OpenEdition DCE introduces new indicators in the
ACEE.	These	indicators mark	the ACEE clientas a ACEE. Client ACEEs are

created by OS/390 OpenEdition and RACF on behalf of multithreaded unau application servers on OS/390. There are two types of client ACEE:

ŸUnauthenticated client ACEE

When	an unauthenticated client ACEE is used in an access control de
two	authorization checks occur.
