PI14841: z/OSMF V2R1 generates spurious ICH408I messages on user login

Fixes are available

APAR status

Closed as program error.

Error description

When users log into z/OS Management Facility V2R1 the system may
generate security audit messages such as ICH408I from RACF or
equivalent message from 3rd party security products.

The messages will describe that a certain user has insufficient
authority to access one or more of the ZOSMF resources in class
ZMFAPLA.

These messages do not affect the operation of the z/OS
Management Facility. All functions should operate normally.
These represent interrogations for access and should not be
audit-logged as access attempts.
 EXTERNAL SYMPTOMS:
 Messages include:

 ICH408I USER(xxxx) GROUP(yyyy) NAME(####################)
   IZUDFLT.ZOSMF.ADMINTASKS.LINKSTASK CL(ZMFAPLA )
   INSUFFICIENT ACCESS AUTHORITY
   FROM IZUDFLT.ZOSMF.ADMINTASKS.** (G)
   ACCESS INTENT(READ   )  ACCESS ALLOWED(NONE   )

 Depending on the logging and audit configuration of the
 system's security product, successful checks may also generate
 messages when users login.
 ANALYSIS:
 The z/OSMF Logon routines attempt to verify the user's access
 to different z/OSMF features by probing the system's SAF
 security product. The results of these probes are used to
 generate the z/OSMF Navigation Tree for that user. The requests
 are being sent to the security product with a LOG value of ASIS
 leading to messages when a given system is configured to
 audit/log access attempts.

 Note that actual attempts to access and use the various
 protected z/OSMF resources undergo another actual security
 check, so these first probes are not actually for access
 control.
 KNOWN IMPACT:
 No impact to z/OS Management Facility Fuction.

 The messages are spurious and can be ignored.
 ADDITIONAL SYMPTOMS:
 MSGTSS7250E

Local fix

BYPASS/CIRCUMVENTION:
 The messages can be ignored.
 Alternately, in RACF, logging can be disabled for the ZMFAPLA
 class to suppress the messages. (Access attempts occur with
 LOG=ASIS, meaning that system configuration determines whether
 messages are generated.)

 NOTE: Suppressing messages via the security product may also
 hide actual access failures/attempts. Consult your security
 product documentation for more details.

Problem summary

****************************************************************
* USERS AFFECTED:  Users of IBM WebSphere Application Server   *
*                  Liberty Profile and SAF security on z/OS    *
****************************************************************
* PROBLEM DESCRIPTION: Using the SAF authorization provider in *
*                      Liberty results in numerous ICH408I     *
*                      RACF                                    *
*                      messages issued to the MVS console      *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Numerous ICH408I RACF messages may be issued to the MVS console
when Liberty's zosSecurity feature and SAF authorization
provider are enabled.
An example ICH408I message:
ICH408I USER(USER1) GROUP(GROUP1)
BBGZDFLT.MY.APP.RESOURCE.PROFILE CL(EJBROLE)
INSUFFICIENT ACCESS AUTHORITY
ACCESS INTENT(READ   )  ACCESS ALLOWED(NONE   )

Problem conclusion

The Liberty SAF authorization provider was changed to suppress
RACF messages for all JEE security authorization requests. In
addition, the SAFAuthorizationService SPI was enhanced to
include a SAF logging option that allows users to suppress
messages, if desired.

The fix for this APAR is currently targeted for inclusion in fix
pack 8.5.5.3. Please refer to the Recommended Updates page for
