401

[listenlight]

Hi, I've been trying to get this to work. I followed the steps precisely, but all I can get from Twitter is a 401. The only variable seems to be the callback url. What do I use for that in the registration at twitter?

Started POST "/authenticate" for 68.102.115.162 at 2010-06-18 03:30:39
  Processing by UserSessionsController#create as HTML
  Parameters: {"authentication_type"=>"session", "authenticity_token"=>"tZKEeh6Po51UdU4YUnw6ykTT79HJS1f44RM9Uk/weE0=", "openid_identifier"=>"", "oauth_provider"=>"twitter"}
