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)

Methods of Signing Git Commits on MacOS

Last updated March 13, 2024

This Gist explains how to sign commits using gpg in a step-by-step fashion. Previously, krypt.co was heavily mentioned, but I've only recently learned they were acquired by Akamai and no longer update their previous free products. Those mentions have been removed.

Additionally, 1Password now supports signing Git commits with SSH keys and makes it pretty easy-plus you can easily configure Git Tower to use it for both signing and ssh.

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here for signing your commits with GPG.
