How to Configure Browsers for Kerberos Authentication

How to enable specific web browsers to use SPNEGO to negotiate Kerberos authentication.

The browser configurations below are required only for those browsers used to connect to component web interfaces with the Require Authentication for HTTP Web Consoles configuration property enabled. The settings below enable the respective browser to use SPNEGO to negotiate Kerberos authentication for the browser. The host running the browser must have a valid TGT to authenticate to Kerberos Web Consoles.

Mozilla Firefox

  1. Open the low level Firefox configuration page by loading the about:config page.
  2. In the Search text box, enter: network.negotiate-auth.trusted-uris
  3. Double-click the network.negotiate-auth.trusted-uris preference and enter the hostname or the domain of the web server that is protected by Kerberos HTTP SPNEGO. Separate multiple domains and hostnames with a comma.
  4. Click OK.
