I use Openfire jabber server and Pandion as clients. ICQ transports work well, however I am unable to register the XMPP transport. The idea is to control the IM communication by allowing users to communicate with external IM providers only via Openfire server. I created a test account at jabber.org which I'd like to connect to via Pandion XMPP transport and Openfire. However, when I complete the "Transport configuration" workflow for XMPP, It says "The account was succesfully registered with the transport". After pressing Finish, Pandion shows "Not registered" under XMPP. I am pretty sure, that Openfire is configured correctly (which does not mean it must work correctly). Any ideas how to configure XMPP transport? Thank yoy.
