pam_rootok: Gain only root access

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.

OPTIONS

debug Print debug information.

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 not 0.

EXAMPLES

In the case of the su(1) application the historical usage is to permit the superuser to adopt the identity of a lesser user without the use of a password. To obtain this behavior with PAM the following pair of lines are needed for the corresponding entry in the /etc/pam.d/su configuration file: # su authentication. Root is granted access by default. auth sufficient pam_rootok.so auth required pam_unix.so
