From 0b5204d3d8a549cdfdd1428db8eb17bb270b4ce8 Mon Sep 17 00:00:00 2001 From: Michael Adam Date: Sat, 3 May 2014 02:59:37 +0200 Subject: [PATCH] smbd: fix creation of BUILTIN\{Administrators,Users} when "tdbsam:map builtin = false" In this case, passdb/group mapping is not responsible for the id mapping of the builtins, so the check whether the SID maps to a unix ID is not valid for checking whether the builtin has been created as a proper group. So this patch changes the check to whether we find the builtin in the group mapping database.
