I am using zend framework. Now I want to authenticate users with other already registered accounts using RPX.

I am following the 3 steps as described at RPX site:

1- Get the Widget 
2- Receive Tokens
3- Choose Providers

I created a controller(person) and action(signin) to show widget and my own signin form. When following action (http://test.dev/#person/personsignin) is called then my own login form and widget is shown successfully. # is used in above URL for AJAX indication.

public function personsigninAction() {

        $this->view->jsonEncoded = true;

        // Person Signin Form
        $PersonSigninForm = new Form_PersonSignin();
        $this->view->PersonSigninForm = $PersonSigninForm;
        $this->view->PersonSigninForm->setAction( $this->view->url() );


        $request = $this->getRequest();
        if ( $request->isPost() ) {

        }       
}

There are two problems while login using openid widget:

1. When I am authenticated from outside(for example: Yahoo) then I am redirected to http://test.dev, therefor indexAction in called in indexController and home page is shown. I want to redirect to http://test.dev/#person/personsignin after authentication and want to set session in isPost() condition of personsigninAction() (described above).

2. For now I consider indexAction to be called when outside authentication is done. Now I posted the code from http://gist.github.com/291396 in indexAction to follow step 3 mentioned above. But it is giving me following error:

   An error occured: Invalid parameter: apiKey

Am I using the right way to use this. This is my very first attempt to this stuff. Can someone tell me the exact steps using my above actions? Thanks.
