The "Authentication Failed" Issue cropped up when Facebook changed all their UserIDs. I got around the problem simply by removing the account, rebooting (don't know why that helped), and recreating the account. Thinking about it... this may have been when I used Jabber to do FB.. hmm. Whatever, the timing is right. I have since then got FB working, but with the usual duplicates/merging bug, so I just disabled the account. But what gets me is, if FB now works with XMPP/Jabber, then why is it so difficult to get this working just under the Facebook name and icon. ? I can deal with not having people's facebook status being retrieved (though it is nice), I just want it to be shown as Facebook, not Jabber. Also, to anyone else, I'm on MSN Haze, and it seems flawless in this version.
