From 6a0a0478ad6f77e3279775dcb0dad51bc3b1457a Mon Sep 17 00:00:00 2001 From: Zahari Zahariev Date: Wed, 5 Jan 2011 18:56:23 +0200 Subject: s4/ldapcmp: Two new options are added to the tool The new ones are --base and --scope they give us the opportunity to compare DN subsets of the partitions. Now we are also able to compare any two objects even if they have different DNs. This is exteremely helpful when you are after nasty nTSecurityDescriptor bug.
