Enabling Desktop SSO in Firefox

This is how you can configure Firefox to use Desktop Single Sign On (SSO) / Kerberos authentication:
  • Go to about:config
  • Change your preference network.negotiate-auth.delegation-uris
  • to the domain you want to authenticate against, for example "".
  • Change your preference network.negotiate-auth.trusted-uris
  • to the domain as above.
Now try going to a URL and you should be able to login automatically. This has been tried and tested with Firefox 3.5.

    does not work for me.
    I added the string in the fields as described and it had no effect

  2. You have to replace "" with the actual domain name of the website you are trying to access.
