title: How to turn off autosignin of registered transports in Openfire?
body: <p>This is regarding the gateway XEP 0100 support in Openfire.</p>
  
  <p>I have noticed that for some transports, they are auto-signed in once a connection to openfire succeeds (via the xmpp user). This applies specifically to QQ. How does one turn off this auto-signin feature ? Basically from a client perspective, I want to be able to signin selectively. So when I create an XMPPConnection to openfire, all transports should remain signed off until I send directed Presences to transports.</p>
