Linux Active Directory Integration with SSSD, SSH, and PAM - Guide

By following these practices and understanding the components, you will have a robust setup where Linux and Active Directory work together for seamless user authentication. The key is to verify each piece (DNS, Kerberos, SSSD, PAM) and use the tools available (logs, realm commands, sssctl, etc.) to diagnose issues. With proper configuration, domain users can log into Linux systems using their AD accounts, and administrators can centrally manage credentials and policies in AD while maintaining Linux-specific settings via SSSD.

Automate RHEL 9 and CentOS Stream 9 Installation on KVM Using Kickstart

Automating OS installations can save time and ensure consistency, especially when deploying multiple virtual machines. Kickstart is a tool from Red Hat that allows you to automate the installation of RHEL and its derivatives by providing a file with answers to all the installation prompts. In this guide, we'll walk through a beginner-friendly step-by-step process to automate the installation of Red Hat Enterprise Linux 9 and CentOS Stream 9 on KVM using Kickstart. We assume you already have KVM (via libvirt/QEMU) installed and configured on your host system.
