Trying to authenticate a user to Azure AD (EntraID) from Ubuntu 22.04

Question

I have a Ubuntu 22.04 based machine with intune and defender on, no issue and working great

I am trying to authenticate the user and I am following these instructions:

This command returns Realm not found (yes I replaced the values with our org) :)

Thank you for your time and patience. I was able to review the ask and understood that you are trying get your Linux Server joined to Microsoft Entra ID.

Please do correct me if this is not the case by responding in the comments section.

I was able to review the doc and was not sure how did the author managed to get a physical Linux device joined to Entra ID as, Linux OS is only supported for Entra ID registration via Intune agent.

As per Microsoft Entra registered devices documentation, Ubuntu is supported for device registration which does allow to access cloud resources via SSO but not login to the device via Entra ID credentials.

• On the contrary if using an Azure VM, then we could Join an Ubuntu Linux virtual machine to a Microsoft Entra Domain Services managed domain
• If you are looking to login to on-prem server with Entra ID then only way around is to use Azure Arc server and then follow Log in to a Linux virtual machine in Azure by using Microsoft Entra ID and OpenSSH, as This functionality is also available for Azure Arc-enabled servers.
