AdminPro is a user authentication class based on
MySQL and the PHP Session functions. It was
written for Web sites that need some password
protected areas. It includes a user management
application script and a MySQL table setup
application script. The class can allow a user to
login and logout via Web-based forms, expire the
session of an authenticated user if it passed a
given session timeout, display error messages and
point the user to the login page when the user is
not authenticated or the login session expired,
and check whether a logged user has administrator or user group privileges
