NAME
     pam_group -- Group PAM module

SYNOPSIS
     [service-name] function-class control-flag pam_group [options]

DESCRIPTION
     The Group PAM module supports the account management function class.  In terms of the function-class parameter, this is the ``account''
     class.

     The Group account management module permits or denies users based on their membership to a particular group (or groups) specified with the
     group option.  If no groups are specified the default group (``wheel'') will be used.

     The following options may be passed to this account management module:

     deny	 Reverse the meaning of the test, i.e., reject the applicant if and only if he or she is a member of the specified group.  This
		 can be useful to exclude certain groups of users from certain services.

     fail_safe	 If the specified group does not exist, or has no members, act as if it does exist and the applicant is a member.

     group=groupname
		 Specify the name of the group to check.  This can be a comma-separated list (i.e. ``group=admin,wheel'').

     root_only	 Skip this module entirely if the target account is not the superuser account.

     ruser	 Check the membership of the applicant (PAM_RUSER), rather than the target account (PAM_USER)
