    <div class="moz-cite-prefix">Ok. Still the error message on login
      screen is not the responsibility of federation provider though.
      Federation provider is more low level SPI for user's operations.
      You can handle this with Authentication SPI. <br>
      <br>
      For example you can throw the exception from federation provider
      and catch it in authenticator and display some message based on
      that.<br>
