Raw Blame History

From e691257c61813f2cf9513d149ba82b021ec824ee Mon Sep 17 00:00:00 2001
From: Andrew Bartlett <abartlet@samba.org>
Date: Tue, 22 Aug 2023 15:08:17 +1200
Subject: [PATCH 23/28] CVE-2023-4154 dsdb/tests: Extend attribute read DirSync
tests
The aim here is to document the expected (even if not implemented)
SEARCH_FLAG_RODC_ATTRIBUTE vs SEARCH_FLAG_CONFIDENTIAL, behaviour, so
that any change once CVE-2023-4154 is fixed can be noted.
BUG: https://bugzilla.samba.org/show_bug.cgi?id=15424
Signed-off-by: Andrew Bartlett <abartlet@samba.org>
Conflict: NA
Reference: https://download.samba.org/pub/samba/patches/security/samba-4.18.8-security-2023-10-10.patch
[PATCH 23/28] CVE-2023-4154 dsdb/tests: Extend attribute read DirSync
