title: Authentication failure Error: The specified authentication provider is not enabled for this Firebase
body: <p>Using Angular Fire 1.2.0 I am creating a login page to enter into Firebase database using Email and password authentication.I have created following controller:</p>
  
  <pre><code>controller('HomeCtrl',['$scope',"$firebaseAuth",function($scope,$firebaseAuth){
  
  var firebaseObj=new Firebase("https://first-project-3c9ef.firebaseio.com/");
  var auth = $firebaseAuth(firebaseObj);
  $scope.user={};
  $scope.SignIn=function(event){
      event.preventDefault();
      var username=$scope.user.email;
      var password=$scope.user.password;
      auth.$authWithPassword({
          email:username,
          password:password
      })
      .then(function(authData){
          console.log("Authentication successful");
      },function(error){
          console.log("Authentication failure",error);
      });
  }
  
  }]);
  </code></pre>
  
  <p>Even on entering right credentials console is giving authentication failure.
  I have already enabled sign in method as Email and password authentication in my Firebase account,even then it is showing Authentication Failure.
  I am following latest guide of Angular fire.</p>
