Manual Section... (8) - page: pam_nologin
NAMEpam_nologin - Prevent non-root users from login
- pam_nologin.so [file=/path/nologin] [successok]
- Use this file instead the default /etc/nologin.
- Return PAM_SUCCESS if no file exists, the default is PAM_IGNORE.
MODULE TYPES PROVIDED
- The user is not root and /etc/nologin exists, so the user is not permitted to log in.
- Memory buffer error.
- This is the default return value.
- Success: either the user is root or the /etc/nologin file does not exist.
- User not known to the underlying authentication module.
The suggested usage for /etc/pam.d/login is:
auth required pam_nologin.so
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.
