pam_nologin - Prevent non-root users from login
Synopsis
- pam_nologin.so [file=/path/nologin] [successok]
DESCRIPTION
OPTIONS
file=/path/nologin
- Use this file instead the default FC/etc/nologinF[].
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 FC/etc/nologinF[] 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 FC/etc/nologinF[] file does not exist.
PAM_USER_UNKNOWN
- User not known to the underlying authentication module.
EXAMPLES
The suggested usage for FC/etc/pam.d/loginF[] 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.
