NAMEpam_rootok - Gain only root access
DESCRIPTIONpam_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.
OPTIONSdebug Print debug information.
MODULE TYPES PROVIDEDThe auth, acct and password module types are provided.
RETURN VALUESPAM_SUCCESS The UID is 0. PAM_AUTH_ERR The UID is not 0.
EXAMPLESIn 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
