Chapter 31. Managing DNS forwarding in IdM

Learn about configuring DNS global forwarders and DNS forward zones in the Identity Management (IdM) Web UI, the IdM CLI, and using Ansible.

31.1. The two roles of an IdM DNS server

DNS forwarding affects how a DNS service answers DNS queries. By default, the Berkeley Internet Name Domain (BIND) service integrated with IdM acts as both an authoritative and a recursive DNS server:

Authoritative DNS server
When a DNS client queries a name belonging to a DNS zone for which the IdM server is authoritative, BIND replies with data contained in the configured zone. Authoritative data always takes precedence over any other data.
Recursive DNS server
When a DNS client queries a name for which the IdM server is not authoritative, BIND attempts to resolve the query using other DNS servers. If forwarders are not defined, BIND asks the root servers on the Internet and uses a recursive resolution algorithm to answer the DNS query.

In some cases, it is not desirable to let BIND contact other DNS servers directly and perform the recursion based on data available on the Internet. You can configure BIND to use another DNS server, a forwarder, to resolve the query.

When you configure BIND to use a forwarder, queries and answers are forwarded back and forth between the IdM server and the forwarder, and the IdM server acts as the DNS cache for non-authoritative data.

31.2. Adding a global forwarder in the IdM Web UI

Prerequisites

  • You are logged in to the IdM WebUI as IdM administrator.
  • You know the Internet Protocol (IP) address of the DNS server to forward queries to.

Procedure

  1. In the IdM Web UI, select Network Services DNS Global Configuration DNS.

Follow this procedure to add a global DNS forwarder by using the command line (CLI).

Prerequisites

  • You are logged in as IdM administrator.
  • You know the Internet Protocol (IP) address of the DNS server to forward queries to.

Procedure

  • Use the ipa dnsconfig-mod command to add a new global forwarder. Specify the IP address of the DNS forwarder with the --forwarder option. 

    [user@server ~]$ ipa dnsconfig-mod --forwarder=10.10.0.1
Server will check DNS forwarder(s).
This may take some time, please wait ...
  Global forwarders: 10.10.0.1
  IPA DNS servers: server.example.com

Verification

  • Use the dnsconfig-show command to display global forwarders. 

    [user@server ~]$ ipa dnsconfig-show
  Global forwarders: 10.10.0.1
  IPA DNS servers: server.example.com
    Copy to Clipboard Toggle word wrap

31.4. Adding a DNS Forward Zone in the IdM Web UI
Link kopieren

Follow this procedure to add a DNS forward zone in the Identity Management (IdM) Web UI.

Important

Do not use forward zones unless absolutely required. Forward zones are not a standard solution, and using them can lead to unexpected and problematic behavior. If you must use forward zones, limit their use to overriding a global forwarding configuration.

When creating a new DNS zone, Red Hat recommends to always use standard DNS delegation using nameserver (NS) records and to avoid forward zones. In most cases, using a global forwarder is sufficient, and forward zones are not necessary.

Prerequisites

  • You are logged in to the IdM WebUI as IdM administrator.
  • You know the Internet Protocol (IP) address of the DNS server to forward queries to.

Procedure

  1. In the IdM Web UI, select Network Services DNS Forward Zones DNS.

    [user@server ~]$ ipa dnsforwardzone-add forward.example.com. --forwarder=10.10.0.14 --forwarder=10.10.1.15 --forward-policy=first

Zone name: forward.example.com.

31.6. Establishing a DNS Global Forwarder in IdM using Ansible
Link kopieren

Follow this procedure to use an Ansible playbook to establish a DNS Global Forwarder in IdM.

In the example procedure below, the IdM administrator creates a DNS global forwarder to a DNS server with an Internet Protocol (IP) v4 address of 8.8.6.6 and IPv6 address of 2001:4860:4860::8800 on port 53.

Prerequisites

  • You have configured your Ansible control node to meet the following requirements:

    • You are using Ansible version 2.15 or later.
    • You have installed the freeipa.ansible_freeipa collection.
    • The example assumes that in the ~/MyPlaybooks/ directory, you have created an Ansible inventory file with the fully-qualified domain name (FQDN) of the IdM server.
    • The example assumes that the secret.yml Ansible vault stores your ipaadmin_password and that you have access to a file that stores the password protecting the secret.yml file.
  • The target node, that is the node on which the freeipa.ansible_freeipa module is executed, is part of the IdM domain as an IdM client, server or replica.

Procedure

  1. Navigate to the /usr/share/ansible/collections/ansible_collections/freeipa/ansible_freeipa/playbooks/dnsconfig directory: 

    $ cd /usr/share/ansible/collections/ansible_collections/freeipa/ansible_freeipa/playbooks/dnsconfig
    Copy to Clipboard Toggle word wrap

  2. Make a copy of the set-configuration.yml Ansible playbook file. For example: 

    $ cp set-configuration.yml establish-global-forwarder.yml
    Copy to Clipboard Toggle word wrap
  3. Open the establish-global-forwarder.yml file for editing.

  4. Adapt the file by setting the following variables:

    1. Change the name variable for the playbook to Playbook to establish a global forwarder in IdM DNS.
    2. In the tasks section, change the name of the task to Create a DNS global forwarder to 8.8.6.6 and 2001:4860:4860::8800.

    3. In the forwarders section of the freeipa.ansible_freeipa.ipadnsconfig portion:

      1. Change the first ip_address value to the IPv4 address of the global forwarder: 8.8.6.6.
      2. Change the second ip_address value to the IPv6 address of the global forwarder: 2001:4860:4860::8800.
      3. Verify the port value is set to 53.

    4. Change the forward_policy to first.

      This the modified Ansible playbook file for the current example: 

    ---
- name: Playbook to establish a global forwarder in IdM DNS
  hosts: ipaserver

  vars_files:
  - /home/user_name/MyPlaybooks/secret.yml
  tasks:

  hosts: ipaserver

  vars_files:
  - /home/user_name/MyPlaybooks/secret.yml
