Section: Linux-PAM Manual (8)
- is a helper program for the pam_unix module that updates the password of a given user. It is not intended to be run directly from the command line and logs a security violation if done so.
The purpose of the helper is to enable tighter confinement of login and password changing services. The helper is thus called only when SELinux is enabled on the system.
