Exactly. It proves it's Adrian. What you *do* with that information is
an entirely different question.

Many people manage to conflate "authentication" and "authorization",
which are two entirely different things in the security world. My favorite

Authentication: "Yes, your driver's license does say you're Jeffrey Dahmer".
Authorization: "Would you like to borrow a steak knife, Jeffrey?"

(For the non-US people - Dahmer was a notorious serial killer and cannibal:
