LF201 - Lab 1.1 - sudoers


I'm beginning the course right now.
Sorry for the naivete of my questions.

I just read the paper Lab 1.1.

On my Debian 10, in order to add the user to sudoers group, I just used to type the command:

´usermod -aG sudo myUser`

This works because in Debian10 there is already a 'sudo' group in /etc/group.

Which approach is better?
the ´/ect/sudoers.d/myUSer` approach either the 'add to group' approach?

Thank you in advance for your answers.

    Adding the user to the sudo group gives them access to run what is declared in the /etc/sudoerr.d/ files. If you look at the file, myUSer for example, it may have a line which looks like this: sudo ALL=(ALL:ALL) ALL , which determines what the members of sudo group can do using the sudo command.

    Hello serewicz,
    thank you for your answer, that suggested me the solution.
    In fact there is not a /etc/sudoers.d/myUSer file, but if I read the content of /etc/sudoers I read:

    # Allow members of group sudo to execute any command
    %sudo ALL=(ALL:ALL) ALL

    So, as you say,
    usermod -aG sudo myUser
    enable the option for myUser expressed in /etc/sudoers

    Thank you for your suggestion!
