    MoinMoin - http authentication

    You need either your webserver configured for doing HTTP auth (like Apache
    reading some .htpasswd file) or Twisted (will accept HTTP auth against
    password stored in moin user profile, but currently will NOT ask for auth)
    or Standalone (in which case it will ask for auth and accept auth against
    stored user profile.)
