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 and in the enforcing mode 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. SEE ALSO
