Basic HTTP/1.0 Authentication

This module implements ``Basic`` authentication as described in
HTTP/1.0 specification [1]_ .  Do not use this module unless you
are using SSL or need to work with very out-dated clients, instead
use ``digest`` authentication.

>>> from paste.wsgilib import dump_environ
>>> from paste.httpserver import serve
>>> # from paste.auth.basic import AuthBasicHandler
>>> realm = 'Test Realm'
>>> def authfunc(environ, username, password):
...     return username == password
>>> serve(AuthBasicHandler(dump_environ, realm, authfunc))
serving on...

    HTTP/1.0 ``Basic`` authentication middleware

    Parameters:

        ``application``

            The application object is called only upon successful
            authentication, and can assume ``environ['REMOTE_USER']``
            is set.  If the ``REMOTE_USER`` is already set, this
            middleware is simply pass-through.

        ``realm``

            This is a identifier for the authority that is requesting
            authorization.  It is shown to the user and should be unique
            within the domain it is being used.

        ``authfunc``

            This is a mandatory user-defined function which takes a
            ``environ``, ``username`` and ``password`` for its first
            three arguments.  It should return ``True`` if the user is
            authenticated.
