authentication

... but still be required for applications that need admin privilegies?

In order to allow the following:

$ apache2ctl restart
httpd not running, trying to start
(13)Permission denied: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

$ sudo !!
sudo apache2ctl restart             #no password asked
$                                   #works!

For reference I've seen this setup on amazon's e3 instances

Any idea?
