The LDAP Tool Box project provides a set of LDAP-related applications, administrative tools, and other utilities. They have just released the version 1.4.2 of their Self Service Password tool, which is a PHP application that allows users to change their password in an LDAP directory. This is a bugfix release that appears to fix an issue with captchas and an issue in which a proposed new password could be incorrectly rejected when using SMS-based password reset.
