Regarding this function in AkActionController: function _authenticationRequest($realm) { header('WWW-Authenticate: Basic realm="' . str_replace('"','',$realm) . '"');

    if(method_exists($this, 'access_denied')){
        $this->access_denied();
    }else{
        header('HTTP/1.0 401 Unauthorized');
        echo "HTTP Basic: Access denied.\n";
        exit;
    }
}

I added the following in my project's ApplicationController:

function access_denied() {
    echo "test of application_controller:access_denied";
    exit;
}

I then executed my project (which includes the Admin plugin) and entered an invalid password. The message displayed is the one from AkActionController, indicating to me that <code>if(method_exists($this, 'access_denied'))</code> returned a false value.

What might I have done wrong, please?
