Hi!

I'm having trouble to connect to the MSN network using Pidgin 2.3.1. I
had no problem before yesterday. Since then I did not update anything,
did nothing to my system, but Pidgin won't connect. I recieve "Unable to
connet Unable to authenticate" messages. I can sign on using
http://mobile.live.com/pocketpc so my msn account should be OK.

Here is what I capture usinh tshark:

[11:54:14][ root at centaurus:~ ](pts/7)# tshark -i eth0 port 1863
Running as user "root" and group "root". This could be dangerous.
