Simon & Ed,

We used to use adoption as only way to derive authority
on our system. This allowed us to secure files to applications
combined with users. We did use the end adopt option where
necessary (like anyplace that a command line could be
exposed). The decision to end adoption in triggers forced
us to use profile swapping.

In order to get functionality that is as secure and flexible as
adoption, I had to jump through quite a few hoops. Swapping
group profiles does have some advantages and can do
some things that adoption cannot, I just wish it were easier
to use.

Triggers may be treated like exit programs, but they are not
really that similar. I would be happier if you could specify
whether a trigger propagated adoption. I can certainly
understand why adoption is not propagated through a
server exit.

This function is there if you are willing to use the Suppress Adopted
Profile option on the Modify Invocation Authority Attributes
Call External (CALLX), or Transfer Control (XCTL) MI instructions. See for the latest
description of
these instructions.

It is true, OS/400 suppress adopted authority when calling almost all
programs. As you guessed we do not prevent the called exit program
adopting is owners authority.
