Just so you know when the file is parsed settings are taken in order. So later settings if in conflict override earlier lines. As far as the sudoers.d folder if there is nothing in it then it would not be overriding the settings in sudoer. sudoer.d is a directory with special permission settings that provides a way to extend the sudoer file without modifying it directly. </div>

Caution: Regarding sudoers.d Adding or modifying files in this directory without knowing or setting the proper file permissions will render your system sudo permissions inoperable requiring you to either boot from a live CD or booting in recovery mode to fix the problem.</div>

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>
