You could try user profile handle switching to a profile that has the
*iosyscfg authority.

Hi All

I've been working on some small programs that make changes requiring
*IOSYSCFG which are to be run at startup. All the programs work as expected
except for one thing: adopted authority does not provide *IOSYSCFG to the
user that calls the program.

What I found when I added a call to my program into the program specified
in QSTRUPPGM was that job QSTRUPJD would fail even though the program
making the changes was using adopted authority.

Looking in the Security Reference I can't see anything specific about
*IOSYSCFG not being allowed for adopted authority, but I note that most of
the examples relate to object security.

To test I wrote a small program that adds a host table entry:


I then compiled the program with USRPRF(*OWNER) and made sure the owner had
*IOSYSCFG special authority. When I run the program using a profile without
TCP8050: *IOSYSCFG authority required to use ADDTCPHTE.

What is even stranger to me is that if I change the program specified in
QSTRUPPGM to USRPRF(*OWNER) and change the owner of that program to a
profile with *IOSYSCFG special authority, the call to the program requiring
*IOSYSCFG runs as expected and QSTRUPJD completes normally.

This seems like a bug, but it would not surprise me if there is a security
exception somewhere that I just haven't found.

Any other theories or suggestions ?
