RE: Odd security issue with adopted authority

How does the new group of users differ from existing, comparable users that can use the process?

I'm not clear on what this means in the IBM doc:
"There is a restriction that has been in existence since release 7 of the System 38 operating system that requires the user running the CLP to have authorization to any associated group profiles being referenced in the command."

What level of authorization? It can't be just *USE because *public already has that.
We are still not seeing "what has changed", except that a new group of users started using the process on Thursday, but we see successful CRTUSRPRF's on Thursday, but not Friday. We do break all the connections between Win and i each night.

Charles,

My response does not preclude your answer. Quite the opposite actually.
IBM doesn't specify profile V8GEOFFW has *ALLOBJ authority. The
object owner having *ALLOBJ authority should cover access to any group
profile being utilized. IMHO, something changed so that the program
owner no longer has authority to group profiles.

Thanks,

Gary Monnier

It was working until Friday and suddenly stopped and nothing has changed?
Hmm. Forgive me if I'm skeptical.

IBM's manual states the following about the CRTUSRPRF...

Restrictions: The user of this command must have:

Security administrator (*SECADM) special authority
Use (*USE) authority to the initial program, initial menu, job
description, message queue, output queue, and attention-key-handling
program (if specified)
Change (*CHANGE) and object management (*OBJMGT) authorities
to the group profile and supplemental group profiles (if specified).

Your adopted authority scheme meets these requirements correct? If so
your program should be working.

Did the program get promoted to production recently? Did the user
profile parameter get changed to *USER or, did the program owner get
changed during the promotion? Maybe an audit stated special
authorities should be removed from the user profile and something
was removed? Is there an exit program in place for exit point
QIBM_QSY_CRT_PROFILE?

This has worked for several years, and no recent program change,
ptfs, or profile change that we can detect. It worked up to Friday morning...

Looking at an issue where a program that adopts authority (User
profile
. .
. . . . . . . : *OWNER)
and owner has *ALLOBJ and *SECADM is executing a CRTUSRPRF and not
authorized to the Group Profile of the user to be created.
This is a client job (C#) calling my program

Job . . : QZRCSRVS User . . : QUSER Number . . . :
008237

Message ID . . . . . . : CPF9802 Severity . . . . . . . : 40
Message type . . . . . : Escape
Date sent . . . . . . : 09/14/15 Time sent . . . . . . : 11:4

Message . . . . : Not authorized to object GR_NONXYZ in QSYS.
Cause . . . . . : You do not have the correct authority for object
GR_NONXYZ in library QSYS type *USRPRF.
Recovery . . . : Contact your security officer or the object owner to
obtain the correct authority and try your request again.

This still works in out test partition but not in production.
We allow a select group of users, outside of IT, to manage outside users.
V7R1.
Owner has *ALLOBJ *AUDIT *IOSYSCFG *JOBCTL *SAVSYS
*SECADM *SERVICE *SPLCTL

Program still works fine to change or delete profiles. Only
CRTUSRPRF fails .

Any ideas before call IBM?
