PAM_SELF(8) FreeBSD 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 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.
