I asked for a use case where it made sense to allow access without any
form of authentication. Your response was a use case where someone
needed access from the outside to an unmonitored machine. I failed to
understand why said user was dependent on not having to give a password
for that.

If noone comes up with a proper use case I'll just hack together a patch
that makes it impossible.
