pam_nologin -- NoLogin PAM module
[service-name] module-type control-flag pam_nologin [options]
The NoLogin 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. It also provides a null func- tion for session management. NoLogin Authentication Module The NoLogin authentication component (pam_sm_authenticate()), always returns success for the superuser, and returns success for all other users if the file /etc/nologin does not exist. If /etc/nologin does exist, then its contents are echoed to non-superusers before failure is returned. If a "nologin" capability is specified in login.conf(5), then the file thus specified is used instead. This usually defaults to /etc/nologin. 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.
