UNIX_UPDATE(8) Linux-PAM Manual UNIX_UPDATE(8)
NAME
unix_update - Helper binary that updates the password of a given
user
SYNOPSIS
unix_update [...]
DESCRIPTION
unix_update 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.
The interface of the helper - command line options, and
input/output data format are internal to the pam_unix module and
it should not be called directly from applications.
