XMPP Server DialBack failure not logged in the Debug Log File

I have configured OpenFire within federation with Lync Proxy XMPP.

Unfourtunaly, it was not easy but now, is working

After some issues, the main issue was that the communication only works from OpenFire -> Lync. The reverse (Lync -> Openfire) doesn't worked...

After more than a week of debug, analyzing all the trafic between the servers, we find that the TCP dialback was invalid. It was not shown in the Logs, it was detected only using wireshark.

So, after expering this, looking to help the Troubleshooting for the future users, I would like to suggest to include more debug messages.

The debug messages presented are:

Log:

-------------------------------------------------------------------------------- ---

2013.07.18 11:49:38 org.jivesoftware.openfire.server.ServerDialback - ServerDialback: RS - Connection to AS: *****.pt successful

2013.07.18 11:49:38 org.jivesoftware.openfire.server.ServerDialback - ServerDialback: RS - Closing connection to Authoritative Server: *****.pt

-------------------------------------------------------------------------------- ---

However, the follow XMPP message was sent to the remote server:

-------------------------------------------------------------------------------- ---

<db:result from="xxxxxxx.pt" to="*****.pt" type="invalid"/>

-------------------------------------------------------------------------------- ---

I would like to suggest to include the following line to help the Troubleshooting:

Class: ServerDialback.java

https://geni-imf.renci.org/trac/browser/openfire/openfire/src/java/org/jivesoftw are/openfire/server/ServerDialback.java

563                        boolean valid = verifyKey(key, streamID.toString(), recipient, hostname, socket);

564   

565                        Log.debug("ServerDialback: RS - Sending key verification result to OS: " + hostname);

566                        sb = new StringBuilder();

567                        sb.append("<db:result");

568                        sb.append(" from=\"").append(recipient).append("\"");

569                        sb.append(" to=\"").append(hostname).append("\"");

570                        sb.append(" type=\"");

571                        sb.append(valid ? "valid" : "invalid");

572                        sb.append("\"/>");

573                        connection.deliverRawText(sb.toString());

Thank you,
