trouble on login

[GoogleCodeExporter]

What steps will reproduce the problem?
1. jc = new JabberClient();
                jid = new JID("xxx@gmail.com");
                jc.LocalCertificate = null;
                jc.Server = jid[i].Server;
                jc.Password = "xxx";
                jc.User = jid[i].User;
                jc.AutoPresence = true;
                jc.AutoRoster = true;
                jc.AutoReconnect = -1;
                jc.AutoLogin = false;
                jc.PlaintextAuth = true;
                jc.AutoIQErrors = true;
                jc.RequiresSASL = true;
                jc.NetworkHost = "talk.l.google.com";
                jc.Port = 5222;
                jc.Connect();
                jc.Login();
                jc.OnAuthenticate += new bedrock.ObjectHandler(j_OnAuthenticate);
...
void j_OnAuthenticate(object sender)
        {
            jc.Message("yyy@gmail.com", "test");
        }

What is the expected output? What do you see instead?
I expect successfull login, but I see IsAuthenticated==false.
