title: How can I find the real user JID of user in MUC?
body: <p>When I join in a room XMPP xmpp, usually the other user see my JID as <code>myconference@conference.localhost/myname</code> instead of <code>myname@localhost</code>.
  Pidgin is able to recover also my real JID when I talk with some of my friends (<code>myname@localhost</code>).</p>
  
  <p>How is it possible? What kind of request should I make to the server?
  This is important for me, because when I start talking with someone, I don't want to open two tabs, only because my client believes that my friend that I can see both in my roster and in the group roster, isn't the same guy.</p>
