Information about user in muc presence frame

Hello

This is my story i wrote a chat application (gwt, lib: emite) with openfire 3.8.1. My applicationassumes that
all usershave access to main (static) room, so do not user roster im my app, because i get all info about status from that main room. My app works great, but when i update openfire to 3.8.2 ther is a one problem. Now my presence frame does not contain information about useruri, ther is my code snippet:

final XmppURI occupantURI = presence.getFrom();final Presence.Type type = presence.getType(); 
................................... if (!Presence.Type.error.equals(type)) {            final XMLPacket xmuc = presence.getExtension("x", XmppNamespaces.MUC_USER); //http://jabber.org/protocol/muc#user            if (xmuc != null) {                final XMLPacket item = xmuc.getFirstChild("item");                final String affiliation = item.getAttribute("affiliation");                final String role = item.getAttribute("role");                               XmppURI userUri = XmppURI.uri(item.getAttribute("jid")); <-- Now this is null !}

As you can see, presence stanza contains info in http://jabber.org/protocol/muc#user namespace about user, but now ther is null :/

Is there anyconfiguration in server (openfire ver 3.8.2) that this information about user is in muc presence frame ?

I also must mention that all my users is comming using LDAP connection .

Thanks for response
