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 + + + + + + + + Use this file instead the default + /var/run/nologin or + /etc/nologin. + + + + + + + + + + Return PAM_SUCCESS if no file exists, the default is PAM_IGNORE. + + + + + + + + MODULE TYPES PROVIDED + + The and 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 + 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. + + + + + SEE ALSO + + + nologin5 + , + + pam.conf5 + , + + pam.d5 + , + + pam8 + + + + + + AUTHOR + + pam_nologin was written by Michael K.
