User Authentication - Objective-C / Cocoa / Sandbox

First of all, please note that I am looking for a solution that works as part of the recommendations for a review of MAS and, in particular, for the application sandbox.

I would like to know if there is a way to authenticate the user before allowing them to make changes to sensitive preferences. For example, the System Preferences application does this using the lock icon: enter image description here

I suspect that system settings should do this because some preference files need root permissions that need to be changed.

In my case, I should not run any such "sudo-esque" operation, so I do not need escalation of privileges. All I want to do is make sure that the person who wants to change the settings of my application is actually a guy who owns a Mac or created a current Mac account (in short, he knows the password for the current user registered in the system).

Any ideas?

There is no supported API for this, and even if you find a workaround, your application will most likely be rejected from the Mac App Store to request a password from the user.
