     pam_wheel -- Wheel	PAM module

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

     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
     authentication 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
		      (default ``wheel'') group.  Returns failure instead of
		      success.	Mainly of use with the group=foo option.

     group=foo	      checking for membership of group foo instead of the
		      default 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.

     getlogin(2), syslog(3), group(5), pam.conf(5), pam(8)
