PAM_ROOTOK(8)
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 /etc/pam.d/su
configuration file: - # su authentication. Root is granted access by default.
auth sufficient pam_rootok.so
auth required pam_unix.so
