Troubleshoot an Issue with the Pluggable Authentication Module

The Pluggable Authentication Module (PAM) provides low-level authentication integration for other applications and services, such as Samba. When these services break in a way that interrupts our ability to authenticate, we should know how to discover the source of the issue and recover efficiently. In this lab, we troubleshoot a broken Samba installation upon discovering we cannot log in as the `cloud_user`. _This lab is not approved or sponsored by Red Hat._
