We use Kerberos for web authentication and have for years, but not with
single sign-on through NAT (since the only way we have to do SSO that way
is via a callback, which doesn't work through NAT or firewalls).  We're
almost done with the next version of the Apache modules and the like and
it will be open source (although right now you could use pubcookie or some
of the other similar ideas that are already out there).

The current version of the S/Ident callback library and Unix responder
supports Kerberos v5 as well as Kerberos v4 and is available at:


Obviously native HTTP authentication using Kerberos would be a lot nicer,
