pam_nologin

PAM_NOLOGIN(8)							 Linux-PAM Manual						    PAM_NOLOGIN(8)

NAME

       pam_nologin - Prevent non-root users from login

SYNOPSIS

       pam_nologin.so [file=/path/nologin] [successok]

DESCRIPTION

       pam_nologin is a PAM module that prevents users from logging into the system when /etc/nologin exists. The contents of the /etc/nologin
       file are displayed to the user. The pam_nologin module has no effect on the root user's ability to log in.

OPTIONS

       file=/path/nologin
	   Use this file instead the default /etc/nologin.

       successok
	   Return PAM_SUCCESS if no file exists, the default is PAM_IGNORE.

MODULE TYPES PROVIDED

       The auth and acct module types are provided.

RETURN VALUES

       PAM_AUTH_ERR
	   The user is not root and /etc/nologin exists, so the user is not permitted to log in.

       PAM_BUF_ERR
	   Memory buffer error.

       PAM_IGNORE
	   This is the default return value.

       PAM_SUCCESS
	   Success: either the user is root or the /etc/nologin file does not exist.

       PAM_USER_UNKNOWN
	   User not known to the underlying authentication module.

EXAMPLES

       The suggested usage for /etc/pam.d/login is:

	   auth  required  pam_nologin.so

NOTES

       In order to make this module effective, all login methods should be secured by it. It should be used as a required method listed before any
       sufficient methods in order to get standard Unix nologin semantics. Note, the use of successok module argument causes the module to return
       PAM_SUCCESS and as such would break such a configuration - failing sufficient modules would lead to a successful login because the nologin
       module succeeded.
