.SH "DESCRIPTION"
.PP
\fIunix_update\fR
is a helper program for the
\fIpam_unix\fR
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\&.
.PP
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\&.
.PP
The interface of the helper \- command line options, and input/output data format are internal to the
\fIpam_unix\fR
module and it should not be called directly from applications\&.
