RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Doc Type: Technology Preview
Doc Text:
.DNSSEC available as Technology Preview in IdM Identity Management (IdM) servers with integrated DNS now implement DNS Security Extensions (DNSSEC), a set of extensions to DNS that enhance security of the DNS protocol. DNS zones hosted on IdM servers can be automatically signed using DNSSEC. The cryptographic keys are automatically generated and rotated. Users who decide to secure their DNS zones with DNSSEC are advised to read and follow these documents: * link:http://tools.ietf.org/html/rfc6781#section-2[DNSSEC Operational Practices, Version 2] * link:http://dx.doi.org/10.6028/NIST.SP.800-81-2[Secure Domain Name System (DNS) Deployment Guide] * link:http://tools.ietf.org/html/rfc7583[DNSSEC Key Rollover Timing Considerations] Note that IdM servers with integrated DNS use DNSSEC to validate DNS answers obtained from other DNS servers. This might affect the availability of DNS zones that are not configured in accordance with recommended naming practices described in the link:https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Networking_Guide/ch-Configure_Host_Names.html#sec-Recommended_Naming_Practices[Red Hat Enterprise Linux Networking Guide].

Description Martin Kosek 2014-07-02 07:12:34 UTC
This bug is created as a clone of upstream ticket:

bind-dyndb-ldap in Fedora 20 plans to introduce DNSSEC support. Add support to FreeIPA as well.

Related bind-dyndb-ldap ticket: https://fedorahosted.org/bind-dyndb-ldap/ticket/56

Related bind-dyndb-ldap design documents:
* https://fedorahosted.org/bind-dyndb-ldap/wiki/BIND9/Design/DNSSEC
* https://fedorahosted.org/bind-dyndb-ldap/wiki/BIND9/Design/RBTDB

Related discussion on freeipa-devel: http://www.redhat.com/archives/freeipa-devel/2013-May/msg00177.html

Major challenges in FreeIPA will be a secure synchronization of DNSSEC keys which need to be available to all FreeIPA masters with DNS support. There also should be a possibility to rotate the keys.

Comment 1 Jenny Severance 2014-07-03 14:25:14 UTC
Can you please close this as a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=829395

Comment 2 Martin Kosek 2014-07-04 08:03:52 UTC
I am not sure I want to do that. DNSSEC support in IPA has different scope that DNSSEC support in bind-dyndb-ldap component. It also needs to publish proper interface + secure key exchange for multi-master environment.

Comment 3 Petr Spacek 2014-07-18 12:21:27 UTC
I'm adding DS bugs which hammers performance in cases where SyncRepl is used. (SyncRepl is a requirement for bind-dyndb-ldap version which supports DNSSEC.)

Comment 4 Petr Spacek 2014-07-18 12:23:59 UTC
And also we need SyncRepl support itself.

Comment 8 Martin Kosek 2014-10-21 10:32:25 UTC
Initial upstream support (#3801) was fixed upstream, it will be part of FreeIPA 4.1. See details in

Comment 11 Petr Viktorin (pviktori) 2014-10-29 14:04:51 UTC
Improvements/fixes are being applied upstream, see https://fedorahosted.org/freeipa/ticket/4657 for details.

Comment 13 Petr Spacek 2014-11-14 19:34:21 UTC
Adding dependencies client side: These changes on clients make the feature actually useful.

IMHO we should consider implementing https://fedoraproject.org/wiki/Changes/Default_Local_DNS_Resolver in RHEL too.

Upstream ticket:

Comment 29 Martin Kosek 2015-07-07 08:12:32 UTC
FreeIPA ticket 4462 will not be part of this feature, this part was not done upstream.

Comment 30 Martin Kosek 2015-07-07 08:15:39 UTC
The intended functionality is finished upstream, the feature is now maintenance mode. I am thus moving this RFE to POST.

Comment 35 Petr Spacek 2015-08-26 11:19:52 UTC
Here is more descriptive text for release notes.

Comment 36 Kaleem 2015-09-23 12:56:36 UTC

IPA/bind* rpm version:
[root@dhcp207-229 ~]# rpm -q ipa-server bind bind-pkcs11 bind-dyndb-ldap opendnssec
[root@dhcp207-229 ~]#

Done verification of this RFE by execution of following test cases.
1. Installation of DNSSEC component with a lot of combinations with forwarders(DNSSEC enabled/disabled, DNS component not installed etc), installation of dnssec component after upgrade to RHEL-7.2 .
2. Migration of DNSSEC component to another IPA replica .
3. DNSzone/DNSrecord signing with verification of dnssec chain of trust, enabling/disabling of signing on dnszone .
4. DNSForward zone addition where DNSSEC enabled/disabled.
