NAME

     pam_self -- Self PAM module

SYNOPSIS

     [service-name] module-type control-flag pam_self [options]

DESCRIPTION

     The Self authentication service module for PAM, pam_self provides functionality for only one PAM category: authentication.  In terms of the
     module-type parameter, this is the ``auth'' feature.

   Self Authentication Module
     The Self authentication component (pam_sm_authenticate()), returns success if and only if the target user's user ID is identical with the
     current real user ID.  If the current real user ID is zero, authentication will fail, unless the allow_root option was specified.

     The following options may be passed to the authentication module:

     debug	 syslog(3) debugging information at LOG_DEBUG level.

     no_warn	 suppress warning messages to the user.  These messages include reasons why the user's authentication attempt was declined.

     allow_root  do not automatically fail if the current real user ID is 0.
