Set up single sign-on for Fedora Project services

In addition to an operating system, the Fedora Project provides services for users and developers. Services such as Ask Fedora, the Fedora Project wiki and the Fedora Project mailing lists help users learn how to best take advantage of Fedora. For developers of Fedora, there are many other services such as dist-git, Pagure, Bodhi, COPR and Bugzilla for the packaging and release process.

These services are available with a free account from the Fedora Accounts System (FAS). This account is the passport to all things Fedora! This article covers how to get set up with an account and configure Fedora Workstation for browser single sign-on.

Signing up for a Fedora account

To create a FAS account, browse to the account creation page. Here, you will fill out your basic identity data:

Account creation page

Once you enter your data, the account system sends an email to the address you provided, with a temporary password. Pick a strong password and use it.

Password reset page

Next, the account details page appears. If you want to contribute to the Fedora Project, you should complete the Contributor Agreement now. Otherwise, you are done and you can use your account to log into the various Fedora services.

Configuring Fedora Workstation for single sign-On

Now that you have your account, you can sign into any of the Fedora Project services. Most of these services support single sign-on (SSO), so you can sign in without re-entering your username and password.

Fedora Workstation provides an easy workflow to add your Fedora credentials. The GNOME Online Accounts tool helps you quickly set up your system to access many popular services. To access it, go to the Settings menu.

Click on the option labeled Fedora. A prompt opens for you to provide your username and password for your Fedora Account.

GNOME Online Accounts stores your password in GNOME Keyring and automatically acquires your single-sign-on credentials for you when you log in.

Single sign-on with a web browser

Today, Fedora Workstation supports three web browsers out of the box with support for single sign-on with the Fedora Project services. These are Mozilla Firefox, GNOME Web, and Google Chrome.

Due to a bug in Chromium, single sign-on doesn’t work currently if you have more than one set of Kerberos (SSO) credentials active on your session. As a result, Fedora doesn’t enable this function out of the box for Chromium in Fedora.

To sign on to a service, browse to it and select the login option for that service. For most Fedora services, this is all you need to do; the browser handles the rest. Some services such as the Fedora mailing lists and Bugzilla support multiple login types. For them, select the Fedora or Fedora Account System login type.

That’s it! You can now log into any of the Fedora Project services without re-entering your password.

Special consideration for Google Chrome

To enable single sign-on out of the box for Google Chrome, Fedora takes advantage of certain features in Chrome that are intended for use in “managed” environments. A managed environment is traditionally a corporate or other organization that sets certain security and/or monitoring requirements on the browser.

Recently, Google Chrome changed its behavior and it now reports Managed by your organization or possibly Managed by fedoraproject.org under the ⋮ menu in Google Chrome. That link leads to a page that says, “If your Chrome browser is managed, your administrator can set up or restrict certain features, install extensions, monitor activity, and control how you use Chrome.” However, Fedora will never monitor your browser activity or restrict your actions.

Enter chrome://policy in the address bar to see exactly what settings Fedora has enabled in the browser. The AuthNegotiateDelegateWhitelist and AuthServerWhitelist options will be set to *.fedoraproject.org. These are the only changes Fedora makes.

    I’m getting a “Preauthentication failed” error. Any ideas?

    • Keith

      I was getting the same error message. To resolve, I changed my account password. I am not sure if it was the changing of the password, or the fact that my new password did not contain any special characters … but one of those resolved the issue.

    when trying to upload a new ssh key I keep getting the following error

    Error!

    The following error(s) have occurred with your request:

    gpg_keyid: Error - Invalid character in GPG key id: t
    • Based on that error message, it looks like you’re trying to upload an SSH public key into a GPG key field in FAS. Those aren’t the same kind of keys.

    Running Fedora 30, under Settings, Online Accounts, Add an Account, there is no Fedora option.
