Severity: wishlist



Very simple authmech that requests a webpage over https with basic auth.  If the page is fetched successfully (status 200) the user is authenticated.  Used in conjunction with something like an apache server you can get easy access to the full handful of existing auth modules for things like radius, RSA, etc.
