NAME

pam_rootok - Gain only root access

SYNOPSIS

:pam_rootok.so [debug]

DESCRIPTION

pam_rootok is a PAM module that authenticates the user if their UID is 0. Applications that are created setuid-root generally retain the UID of the user but run with the authority of an enhanced effective-UID. It is the real UID that is checked.

MODULE TYPES PROVIDED

The auth, acct and password module types are provided.

RETURN VALUES

PAM_SUCCESS

The UID is 0.

PAM_AUTH_ERR

The UID is not0.
