NAME

     pam_rootok -- RootOK PAM module

SYNOPSIS

     [service-name] module-type control-flag pam_rootok [options]

DESCRIPTION

     The RootOK authentication service module for PAM, pam_rootok provides functionality for only one PAM category: authentication.  In terms of
     the module-type parameter, this is the ``auth'' feature.  It also provides a null function for session management.

   RootOK Authentication Module
     The RootOK authentication component (pam_sm_authenticate()), always returns success for the superuser; i.e., if getuid(2) returns 0.

     The following options may be passed to the authentication module:

     debug    syslog(3) debugging information at LOG_DEBUG level.

     no_warn  suppress warning messages to the user.  These messages include reasons why the user's authentication attempt was declined.

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
