Reports an authentication failure when HTTP request status is disabled

While this is technically true (authentication *did* fail) it would be useful if the module checked if HTTP requests were allowed first and sent the message that authentication was not attempted because HTTP requests cannot be made, rather than just saying authentication failed. Otherwise the error message is misleading (people think the username/password are wrong, when in fact it is simply that Drupal has no access to the 'net - or thinks it doesn't).
