 /**
  * When this method is called, the backend must check if authentication was
  * successful.
  *
  * The returned value must be one of the following
  *
  * [true, "principals/username"]
  * [false, "reason for failure"]
  *
  * If authentication was successful, it's expected that the authentication
  * backend returns a so-called principal url.
  *
  * Examples of a principal url:
  *
  * principals/admin
  * principals/user1
  * principals/users/joe
  * principals/uid/123457
  *
  * If you don't use WebDAV ACL (RFC3744) we recommend that you simply
  * return a string such as:
  *
  * principals/users/[username]
  *
  * @param RequestInterface $request
  * @param ResponseInterface $response
  * @return array
