Ubuntu :: No SUDO Access When Admin User Created Through Kubuntu User Manager?

Original HOWTO can be found at: [URL]... So the other day I was in IRC and someone had brought up a problem where they created a new Administrative user, but didnt have rights to use sudo. Looked into the problem a little bit to figure out what was wrong, and it turns out that when you create a new user through the user manager (in kubuntu, anyways. Havent tested in Gnome.) the user gets added to the adm group, however, a quick look at the sudoers file shows that its looking for users in the admin group to allow the use of sudo. So, to solve the problem we do the following: If youre on the new admin user (which Im assuming you are) use the following commands:

Code:
su [insert username of old account without brackets]
sudo usermod -G admin [username of new admin account without brackets]
exit

Then simply logout, and then log back in (not always necessary, but the easiest way to flush the permissions.)

Code:
su [insert username of old account without brackets]
Means were going to Switch User to the old admin account
Code:
sudo usermod -G admin [username of new admin account without brackets]
This simply adds the admin group to the secondary group list for the new user
Code:
exit
Pretty self explanatory
