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 ".domain.com".
• 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.
