The first user id (1000) is created when *buntu is installed. That is
the ONLY user that is given sudo privileges because they are
automatically assigned to the admin group. However, anyone who belongs
to the admin group will be able to do use it as well, and using their
The control of sudo is held in the /etc/sudoers file and must be edited
with the command visudo (which actully runs nano to edit the file). You
have to be root to run it, which means either give root a password (via
sudo passwd) or doing a sudo -i. I recommend the latter.
For more information you can consult the man pages for sudo. You can
customize it so certain users can run certain commands, but only the
ones you specify.
Another point of note is that if you happen to run more than one linux
distribution on your computer, you will have access to the home
directory of the user on the other system that shares your user id.
