Comment 1 for bug 229697

Following up from chatroom conversation, where you mentioned the server is swissjabber.eu, the issue is probably that it does not send the <bind> feature we are relying on during the authentication procedure:

DATA <<< <stream:features xmlns:stream="http://etherx.jabber.org/streams"><register xmlns="http://jabber.org/features/iq-register"/><auth xmlns="http://jabber.org/features/iq-auth"/><starttls xmlns="urn:ietf:params:xml:ns:xmpp-tls"/></stream:features>

For comparison, this is what sameplace.cc sends:

DATA <<< <stream:features xmlns:stream="http://etherx.jabber.org/streams"><bind xmlns="urn:ietf:params:xml:ns:xmpp-bind"/><session xmlns="urn:ietf:params:xml:ns:xmpp-session"/></stream:features>

I'll check if I can support that without too much messing in the code...
