PAM_WHEEL(8)		  BSD System Manager's Manual		  PAM_WHEEL(8)

NAME
     pam_wheel -- Wheel	PAM module

SYNOPSIS
     [service-name] module-type	control-flag pam_wheel [options]

DESCRIPTION
     The Wheel authentication service module for PAM, pam_wheel	provides func-
     tionality 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.

   Wheel Authentication	Module
     The Wheel authentication component	(pam_sm_authenticate()), permit	au-
     thentication to members of	a group, which defaults	to "wheel".

     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.

     auth_as_self     check for	"wheel"	membership against the current login
		      name (given by getlogin(2)).

     trust	      return PAM_SUCCESS instead of PAM_IGNORE if the user is
		      a	member of the group (default is	"wheel").

     deny	      invert the operation if the user is a member of the (de-
		      fault "wheel") group.  Returns failure instead of	suc-
		      cess.  Mainly of use with	the group=foo option.

     group=foo	      checking for membership of group foo instead of the de-
		      fault group "wheel".

     noroot_ok	      return PAM_SUCCESS instead of PAM_IGNORE if the user is
		      authenticating to	a user that is not the superuser.

     exempt_if_empty  return PAM_IGNORE	if the specified group (default	group
		      of "wheel") is empty, providing traditional BSD su(8)
		      semantics	permitting any user to "su" if the wheel group
		      is empty.
