+ * Enfore basic authentication by providing a `callback(user, pass)`,

+ * method is provided as well, invoking `callback(user, pass, callback)`. Populates
+ * `req.remoteUser`. The final alternative is simply passing username / password
+ * strings.
+ *
+ * Examples:
+ *
+ *     connect(connect.basicAuth('username', 'password'));
+ *
+ *     connect(
+ *       connect.basicAuth(function(user, pass){
+ *         return 'tj' == user & 'wahoo' == pass;
+ *       })
+ *     );
+ *
+ *     connect(
+ *       connect.basicAuth(function(user, pass, fn){
+ *         User.authenticate({ user: user, pass: pass }, fn);
+ *       })
+ *     );

+ * @param {String} realm
