Fixed In Version:	bind-9.9.4-23.el7	Doc Type:	Bug Fix
Doc Text:	Cause: Previously the BIND server default configuration used DLV (DNSSEC Look-aside Validation) registry provided by ISC (Internet Systems Consortium). The DLV registry was used in the early stages of DNSSEC adaptation ans is not needed any more. Therefore ISC decided to deprecate the service in the near future. Consequence: As a consequence, the BIND server would execute unnecessary steps for some DNS records when trying to validate them using the DLV registry. Fix: The use of DLV registry was removed from the BIND server default configuration. Result: As a result, the default configuration is prepared for DLV registry deprecation. Also BIND server will not try to perform DNS records validation using DLV registry.	Story Points:	---

Description Tomáš Hozza 2015-05-20 11:13:13 UTC

Description of problem:
As mentioned in Bug #1223325, ISC is planning to deprecate their DLV registry in the future. Currently, the default configuration shipped with BIND has DLV enabled.

The usage of DLV should be removed from the default configuration. Unfortunately we will not be able to remove also the ISC's DLV keys from the configuration and package, since this could cause a regression in existing installations.

Version-Release number of selected component (if applicable):
latest

How reproducible:
always

Steps to Reproduce:
1. inspect /etc/named.conf installed by bind package

Actual results:
There is "dnssec-lookaside auto;" line in the options section of the default configuration.

Expected results:
There is NO "dnssec-lookaside auto;" line in the options section of the default configuration.
