Scenario: New Linux administrators using ubuntu destro have been assigned for the server you are in charge of. So far you have been using the root account directly, but now it seems more appropriate to restrict the root account and allow all administrators to gain root privileges whenever needed. Change the password of the local root account to ROOT Create a new local group named 'rootadmin' Leaving the primary group as is, add the existing local users user1, user2 and user3 to group rootadmin Using appropriate sudo configuration, permit local user user1 to execute any command as root without being prompted for a password
