1. Click Application Menu
2. Click Users and Groups
3. Click Manager Groups
4. Scroll down to sudo then click on it and then click Properties
5. Put a check on desired user to add to sudo group, then click on OK

Then when any app does admin stuff and pops up the Authenticate window then
you will get a drop-down list of folks in the sudo group.  I found this out
by looking in /etc/sudoers and it mentioned users in the sudo group would
have sudo privs.  So I created a second user and then added them to the
sudo group.  I picked an app to install and it popped up the Authenticate
window with not just asking for the password but also a drop-down list of
the users in the sudo group.
