chngpwd Description

chngpwd is a secure wrapper to change user passwords another user in a PAM-enabled system. chngpwd is a secure wrapper to change user passwords another user in a PAM-enabled system.chngpwd's main use is as a wrapper for other interfaces to communicate with the user (e.g., Web interface).It was build with security in mind, so there should not be any security bugs or holes opened by it (But you should check by your self before using it). It requires: Authen::PAM from CPAN and Sys::Syslog (your perl distribution should have it already).The main use for this is as a wrapper for changing password securily (e.g. from a web interface). So the cgi or whatever is being used doesn't need to deal with this issues (and run the cgi as suid root).The script is rich in error messages and exit codes, so it is easy to track down errors, misconfiguration and abuses.Also, on some critical circunstances it will try to mail the admin in a unknown event. Everything that it does is also logged to Syslog.As it uses PAM to change passwords, it should work on any PAM aware system (almost all Linux distributions, Solaris and at some extend HP-UX). I just tested it on Linux (Conectiva Linux and Debian btw).
