NAME
pam_self —
Self PAM module
SYNOPSIS
[service-name] module-type control-flag pam_self [options]
DESCRIPTION
The Self authentication service module for PAM 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_DEBUGlevel. 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.
