Subject: [PATCH] Issue 5442 - Search results are different between RHDS10 and

 RHDS11

Bug Description:  In 1.4.x we introduced a change that was overly strict about

                  how a search on a non-existent subtree returned its error code.

                  It was changed from returning an error 32 to an error 0 with

                  zero entries returned.

Fix Description:  When finding the entry and processing acl's make sure to

                  gather the aci's that match the resource even if the resource

                  does not exist.  This requires some extra checks when processing

                  the target attribute.
