Spark unable to login


We have an Openfire 3.6.4 server running on Centos 5

This has been running for about two months now and we have around 80 users. Today I am getting users unable to login. They just get ‘invalid username or password’

The spark debug console window just shows:

<stream:stream to=“aaaaaaaaa.bbbbbbbbbbb.cccc.ddd” xmlns=“jabber:client” xmlns:stream=“” version=“1.0”>


If I turn on Use old SSL port method in Sparks advanced options, connection is immediate.

Both ports 5222 and 5223 are open and I can telnet to them.

If I run lsof against both ports, I get nothing for 5222

lsof | grep 5223

java 3673 daemon 111u IPv6 12449 TCP *:5223 (LISTEN)

I can’t see what has changed. I would really like to find out why this has changed as changing the client configuration in our environment may prove problematic.

Any ideas?
