A configuration option should be provided to allow for users to log in to
hudson. This would have the effect of locking out people who happen upon the
site by accident (and this is quite likely given the predictable URL that Hudson
is generally deployed at).

Ideally, user authentication would be tied to a realm that is associated with a
password file somewhere on the filesystem (i.e. what .htaccess files do in
apache). This password file already exists in my case, so it would be ideal to
be able to tie into this. If not, it is no major deal however.

Open source continuous build server Continuum has a basic authentication system,
this could provide some insight.
