Join Linux Systems to a Windows Active Directory Domain
In today's computing landscape, you'll often find a diverse mix of Windows and Linux systems. In this video, we demonstrate how simple it is to integrate a modern Linux machine into a Windows Active Directory domain. We'll walk you through the process of joining Debian, Red Hat, and SUSE Linux distributions to an Active Directory domain using just a few straightforward commands.
