Is there a CGI script to allow users to change their passwords online?
There are several floating around. The one I use is a Perl script that I wrote myself, user_manage. It works with the password and group files used by the Apache, NCSA httpd, CERN and Netscape Unix servers, and probably other Unix-based servers. Users can use it to safely change their own passwords, and Web administrators can use it to add new users, manipulate groups, and edit the privileges of existing users. You can find this script at http://stein.cshl.org/~lstein/user_manage/ Bill Jones has written a multi-purpose script called WebPass. In addition to allowing users to change their Web passwords, they can also change their POP, log-in and news passwords, if they have them. It uses a combination of Perl and Expect to do its magic. You can find it at: http://web.fccj.org/~wcjones/WebPass.html Several vendors of commercial Web servers also offer remote user administration scripts. See your server documentation for details.
