Allow user to sudo

If you want a user to actually be able to change something, you should add to multiple groups:

AS root:


adduser 'username' adm
adduser 'username' sudo
adduser 'username' lpadmin
adduser 'username' sambashare

Or existing sudoer use sudo first:

sudo adduser 'username' adm
sudo adduser 'username' sudo
sudo adduser 'username' lpadmin
sudo adduser 'username' sambashare
