DO MAKE SURE not to make your logfile publicly readable, or you'll have
created an even bigger security hole.  Even if you only collect the
response to the login: prompt, one of the favourite user errors is to
get out of sync with login, and to type their password when the system
is expecting their login name.  In that case, they usually get back
into sync, and so the response to the next login: prompt is usually the
username which belongs to that password.
