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 SERVICES PROVIDED

Only the auth service is supported.  

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
      

 

SEE ALSO

su(1), pam.conf(5), pam.d(8), pam(8)
