I enjoyed the book "GUI Bloopers" by another Jeff, Jeff Johnson.  But I
disagree with him when he writes that users *should* be told which part
of their login attempt has failed.  I'm colored by my years of work for
the U.S. Department of Defense.  The less revealed, the better.  (As we
programmers say, "Life would be easier without those users.")
