Small security patches


Corinna,

here is an internationalization bug fix, and some preliminary
definitions for a future well_known_creator approach.

Pierre

2002/12/11  Pierre Humblet  <pierre.humblet@ieee.org>

	* security.h: Declare well_known_creator_group_sid.
	* sec_helper.cc: Declare and initialize well_known_creator_group_sid.
	* security.cc (get_user_local_groups): Use LookupAccountSid to find the
	local equivalent of BUILTIN.
