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

NAME
     pam_nologin — NoLogin PAM module

SYNOPSIS
     [service-name] module-type control-flag pam_nologin [options]

DESCRIPTION
     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 function
     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.

SEE ALSO
     syslog(3), login.conf(5), pam.conf(5), nologin(8), pam(8)
