Add Azure Linux 3 support and improve documentation for azureauth package

[ismailhkose]

Hi there!

I'm working on some build scripts that need to run across different Linux distributions, and I've run into a couple of issues with the azureauth package that I'm hoping you can help with:

1. No Azure Linux 3 support: I can't install azureauth on Azure Linux 3 (the successor to CBL-Mariner). This is becoming a real pain point since we're seeing more Azure Linux 3 usage in our environments.

2. Missing documentation: I've been trying to find docs on how to install and use azureauth on ubuntu or other Linux distros, but there doesn't seem to be any public documentation anywhere. I only discovered the Ubuntu packages by accident when browsing the Microsoft package repos.

What I've found so far

I can see that azureauth packages exist for Ubuntu here:

• https://packages.microsoft.com/ubuntu/20.04/prod/pool/main/a/azureauth/
• https://packages.microsoft.com/ubuntu/22.04/prod/pool/main/a/azureauth/

But there's nothing equivalent for Azure Linux 3, which is frustrating because we're trying to standardize our tooling across both Ubuntu and Azure Linux environments.

My use case

I need to authenticate with Azure DevOps for downloading internal packages. Right now I have to write platform-specific code like this:

# This works on Ubuntu
apt update -y
apt install -y azureauth

# This fails on Azure Linux 3 😞
tdnf install -y azureauth  # Package not found

What would help

Azure Linux 3 support: Could you add azureauth packages for Azure Linux 3?

Better documentation: Some basic docs would be incredibly helpful! Things like:

• How to install it on different platforms
• Basic usage examples
• How it relates to regular Azure CLI auth
• When to use azureauth vs other auth methods

Thanks for considering this!
