The documentation is talking about using
AuthorizationExecuteWithPrivleges() to repair a setuid tool that you
may have already created. It is also suggesting that you use the
setuid tool method rather than using
AuthorizationExecuteWithPrivleges(). In this way, the setuid tool can
limit itself to only doing a specific task. It can also ensure that
its caller is authorized to call it and abort in any other circumstance.
All that said, you don't need any setuid bit in order to call
AuthorizationExecuteWithPrivleges() (neither on the calling
application nor on the target application).

Hi All,
I need to access some files in the Applications folder and in order
to do so I did the following:
1. I've created a tool that copies the files into the Applications
folder (using NSFileManager)
2. I'm invoking the tool using AuthorizationExecuteWithPrivileges()
3. In the tool I'm calling setuid(geteuid()) at the begining
4. The tool does not have its setuid bit set
This setup seems to work fine without doing anything regarding the
setuid bit yet the (very unclear and confusing) documentation seems
to refer to AuthorizationExecuteWithPrivileges as something you use
to run a setuid tool.
Should I set the setuid bit? Why?
TIA
