You set up entra id authentication authd ubuntu 24 04 by linking the system daemon to your cloud tenant. This service lets users log in to Linux machines with their corporate accounts. Many teams use this tool to replace old directory setups and local user keys. When teams grant broad root rights to cloud groups, any logged-in user can change system files.
How entra id authentication authd ubuntu 24 04 works
Canonical built this service to link Ubuntu machines straight to cloud identity providers. It works with the standard Linux login stack to check user details during sign-in. First, an admin registers a new cloud app in the Microsoft portal. This step gives you a unique client ID and a tenant ID for your team. Next, the admin installs the daemon and the cloud broker package on the host.
You then write the tenant details into the broker file on the Linux machine. When a user tries to log in, the Linux login stack talks to the daemon. The daemon asks the Microsoft cloud broker to check the user account. The user sees a prompt to check their identity on a second device or browser. Once the cloud approves the login, the daemon makes a local user account on the fly.
It sets up the home folder and assigns a unique user ID right away. The daemon also caches login tokens on the disk for offline use later. This flow works for both desktop screens and remote shell logins over the network.
Managing groups and local sudo rights
Checking identity is only the first half of server control. Once a user lands on the machine, standard Linux file rules take over. Admins must map cloud groups to local Linux groups to give out admin rights. You can set up the broker so only specific cloud groups can log in. Still, many teams map a broad engineering group right to the local sudo group.
That choice gives every developer full root power on the host day and night. If an attacker steals a user token, they gain total control over the server. To lower this risk, teams split users into smaller groups based on daily tasks. Some users only need to read logs, while others need to restart system apps.
Even with small groups, managing local sudo rules across hundreds of hosts takes hard work. You must sync config files across your fleet whenever team roles change. If a file fails to update, an old employee might keep admin rights too long.

What native cloud login solves and what it misses
Using a cloud login service solves the pain of managing local passwords and SSH keys. When someone leaves the company, you block their account in one central cloud portal. They lose the ability to start new sessions on your Ubuntu fleet right away. You also gain multi-factor checks on every login without extra third-party tools.
Yet this native setup only decides who can open a shell on the box. It stops working the moment the user passes the login gate. The login daemon does not watch or control what commands a user runs inside the session. It cannot block a bad script from dropping a local database or deleting files.
It also cannot rewrite sensitive fields like emails or card numbers in command outputs. Standard system logs only show that a session started, not the full context of each action. Teams that need command-level rules and clean audit trails must look beyond basic login daemons.
Govern statements and responses across databases and APIs
Good config and scoped roles are needed setup. They do not check single queries in flight or mask sensitive fields in returned rows. Across Postgres, MySQL, SQL Server, MongoDB, ClickHouse, Kubernetes APIs, SSH, and internal HTTP endpoints, hoop.dev sits inline in the protocol beside each supported service as an open-source proxy, a sidecar for your database or API. For every query or command an AI agent or engineer runs against production, hoop.dev decides to pass, mask, block, or hold it for human approval.
First, hoop.dev guardrails block banned queries before they run or hold risky ones for review, and hoop.dev data masking rewrites matched sensitive values in responses in memory. Furthermore, hoop.dev holds SOC 2 Type II and is open source on GitHub.
Frequently asked questions
Does authd work for SSH logins on Ubuntu servers?
Yes, the service plugs into the standard Linux login modules used by SSH. Users can log in over the network using their cloud account and a second factor.
What happens if the Ubuntu machine loses internet access?
The broker saves a secure token on the local disk after the first login. Users who logged in before can still sign in using their cached credentials when offline.
Can I restrict which cloud users can log in to a specific host?
Yes, you can list allowed users or cloud group IDs in the broker settings. Anyone outside those approved groups will get blocked during the login check.
