Given that I wrote portions of this code, I'm entirely aware of what
it can, and can't do. In situations where the KDC provides no control
over delegation, you do not want every machine in your domain capable
of accepting delegated credentials. The fact that the Firefox switch
controls not just SPNEGO, but also NTLM authentication, means you
have to be additionally cautious if you have a site with machines
under multiple different managements under the same control.

Not all KDCs implement this functionality. Not all sites use AD. The
original poster explicitly " ... does not want to use AD in any
solution".

While I'm here, I should also respond to:

This is not true. You can implement an OpenID solution which
leverages your site's local authentication and a WebSSO mechanism
such as Cosign, to allow single sign-on to appropriate OpenID
services too (removing the final signon step requires that the
service remember the OpenID you used when you last accessed the
site). We have such a service in development.
