Michalis Kargakis 9e6ef6f237 Conform auth check to rfc2616 (#1607)
According to rfc2616[1], the response from a server to a request with
bad credentials should be a 401 instead of a 403. Grin does not have
the concept of identities so it does not actually recognize a user
request with bad credentials.
