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

      The pam_self module and this manual page were developed for the FreeBSD
      Project by ThinkSec AS and NAI Labs, the Security Research Division of
      Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035
      (“CBOSS”), as part of the DARPA CHATS research program.
