gswauth: Fix 403 being returned instead of 401

- 401(Unauthorized) is to be returned when user credentials are
  wrong where as 403(Forbidden) is to be returned when user
  credentials are correct but the user doesn't have the priveleges
  to carry out the operation.

- Also error messages displayed when using swauth-* command line
  utilities have been updated.
