Our webmail (squirrelmail) is doing kerberos authentication.  We gutted
the authentication part of squirrelmail and instead launch a persistant
imtest process, which squirrelmail connects to instead (this was
relatively easy to do, actually -- most of the changes that were
required were in imtest).  This also has the benefit of caching
authentications (like a proxy), since successive page hits just re-use
the same imtest process.

The trick is that you need to get the user's kerberos ticket to the web
server, which we accomplish via a system known as pubcookie, which has
been developed by a few universities.  Its sort of like
kerberos-via-cookies, though the kerberos ticket passing bit is somewhat
disconnected from the main system.
