Managing local users and groups is a key skill for any system administor. In this hands-on lab, we will create, delete, and modify local user accounts, change local user account passwords and adjust password aging, as well as create, delete, and modify local groups and group memberships on RHEL 8. Sometimes we need to give a user account elevated access to one or more commands, but we don’t want to give them ‘root’ privileges, or access to an application user account. Fortunately, we can do this via the ‘sudo’ utility. Understanding how to configure ‘sudo’ properly is an important skill for system administrators. will examine how to configure superuser access using ‘sudo’ on RHEL 8.
