NAME
pam_rootok - Gain only root accessSYNOPSIS
- pam_rootok.so [debug]
DESCRIPTION
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 not0.
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
