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 /var/run/nologin or /etc/nologin exists. The contents of
the 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 /var/run/nologin or /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 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.
