    A little auth module plugin I wrote to allow cross-domain login from · fc9aae80

    emulab to the protogeni wiki, but I use it for all of the wikis. The
    basic idea is that the emulab backend inserts a hash value into the
    cookie table in the trac DB on ops (via ssh). Then Emulab issues a
    redirect over to the trac wiki, with the uid/hash values as arguments
    to the xlogin URL. This hash is use-once; if it exists in the cookies
    table, it is deleted and a new one generated by the underlying auth
    module, and a cookie returned to the browser. The user is thus logged
    in for all subsequent access.
    Why? Cause emulab.net cannot insert auth cookies for protogeni.net, so
    must let the auth module inside trac insert the cookie.
