Zend Twitter: Connecting

I have the following code:

        $twitter = new Zend_Servi开发者_C百科ce_Twitter(array('username' => $this->site->twitter_username, 'accessToken' => $this->site->twitter_password));
        $response = $twitter->account->verifyCredentials();
        print_r($response);
        $twitter->account->endSession();

My username is my Login Username on twitter, my $this->site->twitter_password is my Access Token (oauth_token)

Yet I get:

Zend_Rest_Client_Result Object ( [_sxml:protected] => SimpleXMLElement Object ( [request] => /account/verify_credentials.xml [error] => Could not authenticate you. ) [_errstr:protected] => ) 

I'm unsure where I'm going wrong, any ideas?

I recently blogged about this and have included some instructions that should get you going, let me know if you need any more pointers.
