Hi all.
When trying to connect to openfire from Gajim (one of the most popular UNIX clients) Gajim says that there was something with my user/password and Openfire claims in warn log that:
2013.02.27 11:31:34 org.jivesoftware.openfire.net.StanzaHandler - Unexpected packet tag (not message,iq,presence)<abort xmlns="urn:ietf:params:xml:ns:xmpp-sasl"/>
