Change Password Utility (CPU) gives system administrators the ability to administer users and groups on a wide range of backends, currently including LDAP and flat files. Simply, CPU is for user and group administration. The commandline is almost completely compatible with existing Linux user and group management tools, so it can easily be dropped in place. It supports several different hashing algorithms and allows existing users to be imported from Unix-style passwd and shadow files into the backend of your choice.
