Limiting the use of adopted authority

When a program runs, the program can use adopted authority to gain access to objects. Be careful when allowing programs to adopt authority as it may grant permissions you do not want all the program's users to have.

The program itself can adopt the authority of its owner. This is specified in the user profile (USRPRF) parameter of the program or service program.
The program can inherit and then use adopted authority from a previous program that is still in the job’s call stack. A program can inherit the adopted authority from previous programs even if the program itself does not adopt authority. The use adopted authority (USEADPAUT) parameter of a program or a service program controls whether the program inherits adopted authority from previous programs in the call stack.
