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. + +AUTHOR + +pam_nologin was written by Michael K.
