Thread: xmpp single sign on sso

Hello,

i want to build a very simple xmpp message listener. i start with this:

http://www.javaprogrammingforums.com...smack-api.html

that works great. but i want to authenticate my user with the windows active directory user. but how can i implement this?

the goal is a xmpp client, thats starts automaticly and auth with the ad user and login some chat channels and a small pop have to come, when a new message is in one of this channels.

i hope you can help me.

thanks!

   XMPPConnection connection;
    SASLAuthentication auth;
    public void login(String userName, String password) throws XMPPException
    {
	    ConnectionConfiguration config = new ConnectionConfiguration("testjabber",5222, "Work");
	    connection = new XMPPConnection(config);
	    connection.connect();
	    System.out.println(SASLAuthentication.getRegisterSASLMechanisms());
	    connection.login(userName,"");
    }

I think the Problem is, he dont use the GSSAPI mechanism. He only use the PLAIN method:

[class org.jivesoftware.smack.sasl.SASLGSSAPIMechanism, class org.jivesoftware.smack.sasl.SASLDigestMD5Mechanism, class org.jivesoftware.smack.sasl.SASLCramMD5Mechanism, class org.jivesoftware.smack.sasl.SASLPlainMechanism, class org.jivesoftware.smack.sasl.SASLAnonymous]
Exception in thread "main" SASL authentication failed using mechanism PLAIN: 
	at org.jivesoftware.smack.SASLAuthentication.authenticate(SASLAuthentication.java:325)

but i dont know why?
