  1. Hello!
    Would you be able to specify which platforms are supported? Am planning on using AWS EC2 instance with Ubuntu 22.04 and will need to join that to Azure AD. We have had issues with this earlier this year and am not sure if this step by step guide will resolve it. Thanks!

      1. Are you sure this isn’t for domain services? There is no support currently for joining linux to Entra ID natively without using domain services.

          1. I think what Michael is asking is if you have to have Azure Secure LDAP set up through Azure Domain Services in order for this to function. To be honest, I’m not sure how it would work without that in place…

  2. What if I, as an admin, need to run reports and see what apps are installed. Does this approach help in achieving that?
