The reason that I ask is that it is good practice to test changes to a system that is not critical to your daily uses. This is especially true for Ubuntu where by default the root account is locked. If you don't have a test system and you are using your daily useable system, then you should be testing these changes with a test user account not your only actual user account.</div>

As to the reason that sudo still works without a password, I am not entirely sure but my guess is that the '#' in the /etc/group is being ignored. Usually you remove the user from the group either by:</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small;color:rgb(11,83,148)">

This is basically the same thing. If you are the only user or admin on your system than this is overkill and you could just use the %sudo group stanza as discussed before. However if you are planning or have serveral administrators that will have different permissions than it would be best to re-think not using passwords. </div>
