At XmppPrebind class 450 line:

$challengeResponse = $this->send($domDocument->saveXML());

return $this->replyToChallengeResponse($challengeResponse);

which meaning to reply xmpp server when SASL authenticate success. but at official document i haven't see this step. if i do this. I will got a XmppPrebindException said: Invalid login!!
Here is request and response error xml content (xmpp server is Openfire):

#### request:
<?xml version="1.0" encoding="UTF-8"?>
<body xmlns="http://jabber.org/protocol/httpbind" content="text/xml charset=utf-8" rid="4723813009" xml:lang="en" sid="603v7hlcaw">
    <response xmlns="urn:ietf:params:xml:ns:xmpp-sasl"/>
</body>
### response:
<body xmlns='http://jabber.org/protocol/httpbind' ack='4723813009'><failure xmlns="urn:ietf:params:xml:ns:xmpp-sasl"><not-authorized/></failure></body>

So in my code, I has remove this unnecessary step:

  /**
     * Send challenge request and build DIGEST-MD5 auth string
     *
     * @param Auth_SASL_Common $auth
     * @return string Auth XML to send
     */
    protected function sendChallengeAndBuildDigestMd5Auth(Auth_SASL_Common $auth) {
        $challenge = $this->sendChallenge();

        $authString = $auth->getResponse(self::getNodeFromJid($this->jid), $this->password, $challenge, $this->jabberHost, self::SERVICE_NAME);
        $this->debug($authString, 'DIGEST-MD5 Auth String');

        $authString = base64_encode($authString);

        $domDocument = $this->buildBody();
        $body = self::getBodyFromDomDocument($domDocument);

        $response = $domDocument->createElement('response');
        $response->appendChild(self::getNewTextAttribute($domDocument, 'xmlns', self::XMLNS_SASL));
        $response->appendChild($domDocument->createTextNode($authString));

        $body->appendChild($response);


//        $challengeResponse = $this->send($domDocument->saveXML());
//
//        return $this->replyToChallengeResponse($challengeResponse);
         return $domDocument->saveXML();
    }

Then login, restart, and bind resource is successfully.

The function sendChallengeAndBuildCramMd5Auth too.

Is this reply step not needed?
I had fork your project to: https://github.com/lzqwebsoft/xmpp-prebind-php, remove this step and remove FirePHP (because firebug out), last add translate README to chinese. :)
