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. 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.
