Cannot do Facebook/Twitter integration through Mail, Contacts
I cannot do facebook or twitter integration using the system preferences panel "Mail, Contacts & Calendars". After entering the correct User Name and Password, it takes a minute or so and then IA_ERROR_BAD_CREDS shows up under the passwords box. I know that both the username and pw are correct. This happens for both twitter and facebook.
Console has this to say:
