Add Domain Users as Local Sudoers (Linux, Samba, Winbind)

My first thought was to add the domain user to the wheel group:

usermod -a -G wheel corpdev\\atwlam

Though it is possible to add domain user to wheel, the user is still unable to sudo.

CORPDEV\atwlam@sles12:~> sudo su -

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

root's password:

So the second option would be to add the domain user (or group, e.g. %corpdev\\linux_admins, note the double backslashes) to sudoers:

# visudo

%wheel ALL=(ALL) NOPASSWD: ALL
%corpdev\\linux_admins ALL=(ALL) NOPASSWD: ALL

And there you go, the domain user can now use sudo:

CORPDEV\atwlam@sles12:~> sudo su -
sles12:~ #
