[Macpartners] Jabber settings for iChat

[Helen Rose]

I'm trying to get going with Jabber on iChat (v3.1.1 on OS 10.4.4).  
These are the settings I'm using:

Jabber ID: hrose at mit.edu
Password: (Kerberos pw)
Server: jabber.mit.edu
Port: 5222
Connect using SSL - CHECKED
Allow self-signed certificates - CHECKED
Warn before password is sent insecurely - CHECKED

When I try and connect, iChat returns an error: "Could not connect to  
Jabber. An unexpected SSL error occured. [-9806]"

Can someone point me to my mistake?

Thanks!
