RHEL 9.5 AD Integration with SSSD and Samba (Step-by-Step Guide)

Important Note: (18-Feb-2025) This gist has some issues. Please see the addendum. Thanks @hortimech for pointing this out

A step-by-step configuration guide for setting up RHEL 9.5 with SSSD and Samba for Active Directory integration. Covers all required configuration files, settings, and explanations for each option. Also sources for further documentation and troubleshooting recommendations:

Domain Joining with SSSD (configuring sssd.conf, realmd, Kerberos, and automatic authentication for SSH and Samba)
Samba Configuration with SSSD (using sss as the backend for identity mapping, Kerberos authentication, and ensuring smooth Windows/Mac access)
Kerberos-based Single Sign-On (SSO) (ensuring users can access SMB shares without re-entering credentials)
Offline Authentication (caching credentials for when AD is unreachable)

What are the Kubernetes certifications?

There are four Kubernetes certifications:

Keycloak Cluster Configuration (How to)

This is a short and simple example on how to build a proper Keycloak cluster, using DNS_PING as discovery protocol and an NGINX server as reverse proxy.

If you prefer to use JDBC_PING, see @xgp's example gist here: https://gist.github.com/xgp/768eea11f92806b9c83f95902f7f8f80

Please see also my video about Keycloak Clustering: http://www.youtube.com/watch?v=P96VQkBBNxU
NOTE: The video covers JDBC_PING protocol and uses the legacy Keycloak Wildfly distribution!

Open in Visual Studio Code

Open Automator
Create a new document
Select Quick Action
Set “Service receives selected” to files or folders in any application
Add a Run Shell Script action
- your default shell should already be selected, otherwise use /bin/zsh for macOS 10.15 (”Catalina”) or later
- older versions of macOS use /bin/bash
if you're using something else, you probably know what to do 😉

Linux Networking Reading List

Currently in no particular order. Most of these are kind of ancient.

Where's all the modern documentation? So much of what I've turned up searching is other folks complaining about having few options beyond reading source code.

The OREILLY books, while dated, seem to be some of the best available. Note that these can be read with a 7-day trial. Do this! At least get through the introduction section and first chapter of each to see if it's what you're after.

Git Flow: A Successful Git branching model

Gitflow is a Git workflow design that was first published and made popular by Vincent Driessen at nvie. The Gitflow defines a strict branching model designed around the project release. This provides a robust framework for managing larger projects.

Gitflow is ideally suited for projects that have a scheduled release cycle. This workflow doesn’t add any new concepts or commands beyond what’s required for the Feature Branch Workflow. Instead, it assigns very specific roles to different branches and defines how and when they should interact. In addition to feature branches, it uses individual branches for preparing, maintaining, and recording releases. Of course, you also get to leverage all the benefits of the Feature Branch Workflow: pu

	#!/bin/sh

	VERSION=v0.36.0 # use the latest release version from https://github.com/google/cadvisor/releases
	sudo podman run -d --name cadvisor \
	--volume /:/rootfs:ro \
	--volume /nix:/nix:ro \
	--volume /var/run:/var/run:rw \
	--volume /sys:/sys:ro \
	--volume /sys/fs/cgroup:/sys/fs/cgroup:ro \
	--volume /dev/disk/:/dev/disk:ro \

	# a connection to the Kafka broker (no Zookeeper, REST APIs etc)
	# and the standard kafka-topics, kafka-reassign-partitions scripts
	# that come with Kafka.
