PAM_SELF(8)               BSD System Manager's Manual              PAM_SELF(8)

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 func-
     tionality 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 suc-
     cess if and only if the target user's user ID is identical with the cur-
     rent 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.
