Reset the authentication status before calling the callback
Reset the authentication status before calling the callback

We can't rely on the user to call our _finish method, so depending on that for
resetting is wrong. Also at the point when the operation has finished the
object should always be in the same state, ready to authenticate again (Not
useful for the success case, but good for consistency)
