Auth: Perform authentication only once and not lazily

Browse Source 
Since authentication is now performed even for static
resources, there's no reason anymore to support implicit
authentication. This also limits authentication attempts
to a single one, previously failed attempts were repeated.

Requiring authentication during bootstrapping, i.e. before
authentication has been performed, will now trigger a
deprecation notice.
