Granting `sudo` Privileges to Confined Users

In this lab, we'll review the process of granting `sudo` privileges to SELinux confined users. When working with SELinux confined users, you may run into problems with Linux users not being able to use `sudo` anymore. We'll discuss why this happens and how to resolve the issue. *This course is not approved or sponsored by Red Hat.*
