Firefox Kerberos

Firefox can use Kerberos for single sign-on (SSO) to intranet sites and other protected websites. For Firefox to use Kerberos, it first has to be configured to send Kerberos credentials to the appropriate KDC. Users can enable Kerberos single sign-on (SSO) authentication using preference in their browser profile but it's also possible to set the default for all Firefox users on the system. During my ApacheCon talkthis year, one of the questions from the audience focused on. I am deploying Linux/Firefox on a corporate Kerberos network. I followed this Kerberos-on-Firefox procedure but still Firefox does not connect via the company's Kerberos. I am using Firefox 3.0.18 on RedHat EL Server 5.5. Here is what I did: Run kinit on the command line to create a Kerberos ticket; Check with klist: the ticket is valid until tomorrow, service principal is krbtgt/DC.

In September 2014, Alfresco 5 was released with new reporting and analytics features and an overhaul of its document search tool, moving from Lucene to Solr.[14]

In March 2017, Alfresco 5.2 was released and rebranded as the Digital Business Platform. This included the release of the Application Development Framework with reusable Angular JS(2.0) components.[17]

On February 8, 2018, it was announced that Alfresco was to be acquired by the private equity firm Thomas H. Lee Partners, L.P.[18]

On September 9, 2020, Alfresco was bought by Hyland Software for an undisclosed amount.[19][20]

Firefox Kerberos Authentication

Using Kerberos implies that your client's browser must be configured properly!

Depending upon which browser your clients use, you have to set up the Kerberos configuration in a different way.Please note that without a proper configured browser, the Kerberos token is not sent to the server and so SSO will not work!

Internet Explorer

Firefox Kerberos Proxy Authentication

The URL must be added to Internet options > Security > Local intranet. You can deploy this setting by using a group policy for the node Computer Configuration/Policies/Administrative Templates/Windows Components/Internet Explorer/Internet Control Panel/Security Page/Site to Zone Assignment List. Each of your SSO-enabled sites has to be in the Intranet zone (value = 1).You can use wildcards like 'https://*'.

After you have configured the setting, it should look like this:

Please note, that enforcing a GPO for Site to Zone Assignment List does no longer allow your users to edit the setting on their own! There are two options:

  1. Collect each custom configuration and assemble the complete list. In most cases you can use a wildcard on your internal domain like* and* to include all internal sites.
  2. Configure a custom assignment list by using a logon script or something like OpsCode Chef or Microsoft's Desired State Configuration.

The first option should be the way to go.

Check the other security settings

Please make sure that there your SSO-enabled domain is only entered in the Local intranet zone and nowhere else! If you have falsely entered the same domain in Trusted sites and Local intranet, the first one is used an no Kerberos token is sent by Internet Explorer to the webserver.


In order to use Chrome for SSO you also must deploy the settings shown in the Internet Explorer configuration above.

Newer versions of Chrome do automatically detect the Kerberos negotiation and transmit your token. In case you are using an outdated version of Chrome we highly suggest to update it for security reasons.

If an update is not possible at all, Chrome must be started with the parameter

Firefox Kerberos Gpo


This setting can be automatically deployed by using group policies.

  1. Download the official group policies for Chrome
  2. Follow the installation procedure and open the chrome.admx
  3. Configure a policy for the option AuthServerWhitelist
  4. Deploy the policy


In Firefox you have to go to the about:config page and set the parameters


Firefox Kerberos Gpo

The deployment of these settings can be done by using GPO for Firefox. This is a plug-in for Firefox which itself has to be automatically deployed and/or bundled with your NETLOGON script.
