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
