During the authority-checking process, when any authority is found (even if it is not adequate for the requested operation) authority checking stops and access is granted or denied. The adopted authority function is the exception to this rule.
Adopted authority can override any specific (and inadequate) authority found.
The system verifies a user's authority to an object in the following order:
1. Object's authority - fast path
2. User's *ALLOBJ special authority
3. User's specific authority to the object
4. User's authority on the authorization list securing the object
5. Groups' *ALLOBJ special authority
6. Groups' authority to the object
7. Groups' authority on the authorization list securing the object
8. Public authority specified for the object or for the authorization list securing the object
9. Program owner's authority, if adopted authority is used
Authority from one or more of the user's groups may be accumulated to find sufficient authority for the object being accessed.
