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


Only the auth type is 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 \FC/etc/pam.d/su\F[] configuration file:

# su authentication. Root is granted access by default. auth sufficient pam_rootok.so auth required pam_unix.so

\M[lightgray]\D’P 75u 0 0 0u -75u 0 0 -0u’\M[] \M[lightgray]\D’P 75u 0 0 0u -75u 0 0 -0u’\M[]
