pam_rootok -- Gain only root access
     __________________________________________________________________

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.

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
