OPTIONS

file=/path/nologin

Use this file instead the default /etc/nologin.

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 /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 /etc/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 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.
