What I did in my first posts seems to be wrong in hindsight, as it just allows
every user to access sudo with the user password (?) as I haven't uncommented
the line - Defaults targetpw

What should be the default config now that apparently the user password should
be used? 
Wheel group? back to targetpw? Personally I'm confused, why was there even a
need to change this?
