[horde] explicitly log back into a session using the auth_key

The auth_key cookie is not the session_id; you can't log in with it. It's just a
random hash - essentially a passphrase - that lets us encrypt sensitive session
data, so that a compromise of the session store doesn't compromise user
passwords without additional information.

You want the session id instead. Though I'm not exactly sure what you mean by
sending the response back from a different server, and where/how you intend to
recreate the session.
