Configuring User Accounts and Permissions on a Development Server

In this hands-on lab, you will connect to a Red Hat 8 system using SSH. Once connected, you will use the `useradd` command to add several users, set passwords using the `passwd` command, use the `groupadd` command to add a couple of groups, and use either the `usermod` or `gpasswd` commands to add users to groups. Once the groups are in place, you will grant elevated privileges to a set of users using the new groups and test the permissions by using the `su -` command to switch to a user and attempt to run the commands. *This course is not approved or sponsored by Red Hat.*
