Using sudo without password

Hi all!!!
Do you ever wanted to grant "root" priviledges to a user without having to type the root password?

I needed to have a user capable of performing "admin" tasks at same level as "root". In order to get things done,  I created a user called admin, member of group "users" with password locked (passwd -l admin). This step is important, because it means that no one except root will be able to access the account.
To grant "admin" unlimited access without password, i had to type sudo and include at the end the following line:

admin ALL=(ALL) NOPASSWD: ALL


Have a nice day!!! : )
