So there's yet another case of an upgrade to FC 3 causing an auth problem.

It looks like the client tries to contact the daemon to do the auth by
calling auth_server().  It fails, so the client prints the @ERROR message.

Wayne - is the 'connection unexpectedly closed' normal?  Or does that
indicate that the daemon child probably crashed like it's been doing
in other cases?

Here are some links to related issues that I've compiled:

Hope that helps.

Maybe this issue needs to be added to the Current Issues page?
