Subject: X-FACEBOOK-PLATFORM authentication

Hello,

I have a problem with X-FACEBOOK-PLATFORM authentication mechanism. I tried to find solution on forum, but I found nothing. Everything works fine with DIGEST-MD5.

Here is my code.

his.xmppClient = new XmppClient()
      {
      Password = this.account.Password,
      Username = this.account.Username,
      XmppDomain = this.account.Domain,
      Status = "Online",
      Show = Show.chat,
      Port = 5222,
      StartTls = true,
      Hostname = "chat.facebook.com",
      };

      // Event handlers for Matrix
      this.xmppClient.OnBeforeSasl += this.xmppClient_OnBeforeSasl;
      this.xmppClient.OnLogin += this.XmppClient_OnLogin;
      this.xmppClient.OnAuthError += this.XmppClient_OnAuthError;
      this.xmppClient.OnError += this.XmppClient_OnError;

      this.xmppClient.OnRosterStart += this.XmppClient_OnRosterStart;
      this.xmppClient.OnRosterItem += this.XmppClient_OnRosterItem;
      this.xmppClient.OnRosterEnd += this.XmppClient_OnRosterEnd;
      this.xmppClient.OnReceiveXml += this.XmppClient_OnReceiveXml;
      this.xmppClient.OnSendXml += this.XmppClient_OnSendXml;

      try
      {
      this.xmppClient.Open();
      }
      catch (Exception ex)
      {
      Console.WriteLine("During the open");
      Console.WriteLine(ex.Message);
      }

      Thread.Sleep(500*60);

      this.xmppClient.SendPresence(Show.chat, "Online");

      // Get Online users
      this.xmppClient.OnPresence += this.XmppClient_OnPresence;
      this.xmppClient.AutoRoster = true;

public void xmppClient_OnBeforeSasl(object sender, Matrix.Xmpp.Sasl.SaslEventArgs e)
      {
      Console.WriteLine("OnBeforeSasl");
      e.Auto = false;
      e.SaslMechanism = Matrix.Xmpp.Sasl.SaslMechanism.X_FACEBOOK_PLATFORM;

      e.SaslProperties = new Matrix.Xmpp.Sasl.Processor.Facebook.FacebookProperties
   {
   ApiKey = AppId,
   ApiSecret = AppSecret,
   AccessToken = this.accessToken
   };
      Console.WriteLine(e.SaslProperties);
      }

And XML:

Have you studied this?
http://www.ag-software.net/matrix-xmpp-sdk/matrix-develope…

Do you request the xmpp_login permission?

Yes, I've studied this.
I registered my app on Facebook and in menu "Configure how Facebook refers users to your app" - "Extended permissions" specified xmpp_login, but nothing more.

AFAIK you have to request the permission when you retrieve you token in the web API/Url.
