Chapter 6. Managing DNS forwarding in IdM Follow these procedures to configure DNS global forwarders and DNS forward zones in the Identity Management (IdM) Web UI, the IdM CLI, and using Ansible: The two roles of an IdM DNS server DNS forward policies in IdM Adding a global forwarder in the IdM Web UI Adding a global forwarder in the CLI Adding a DNS Forward Zone in the IdM Web UI Adding a DNS Forward Zone in the CLI Establishing a DNS Global Forwarder in IdM using Ansible Ensuring the presence of a DNS global forwarder in IdM using Ansible Ensuring the absence of a DNS global forwarder in IdM using Ansible Ensuring DNS Global Forwarders are disabled in IdM using Ansible Ensuring the presence of a DNS Forward Zone in IdM using Ansible Ensuring a DNS Forward Zone has multiple forwarders in IdM using Ansible Ensuring a DNS Forward Zone is disabled in IdM using Ansible Ensuring the absence of a DNS Forward Zone in IdM using Ansible 6.1. 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. 6.2. DNS forward policies in IdM IdM supports the first and only standard BIND forward policies, as well as the none IdM-specific forward policy. Forward first (default) The IdM BIND service forwards DNS queries to the configured forwarder. If a query fails because of a server error or timeout, BIND falls back to the recursive resolution using servers on the Internet. The forward first policy is the default policy, and it is suitable for optimizing DNS traffic. Forward only The IdM BIND service forwards DNS queries to the configured forwarder. If a query fails because of a server error or timeout, BIND returns an error to the client. The forward only policy is recommended for environments with split DNS configuration. None (forwarding disabled) DNS queries are not forwarded with the none forwarding policy. Disabling forwarding is only useful as a zone-specific override for global forwarding configuration. This option is the IdM equivalent of specifying an empty list of forwarders in BIND configuration. Note You cannot use forwarding to combine data in IdM with data from other DNS servers. You can only forward queries for specific subzones of the primary zone in IdM DNS. By default, the BIND service does not forward queries to another server if the queried DNS name belongs to a zone for which the IdM server is authoritative. In such a situation, if the queried DNS name cannot be found in the IdM database, the NXDOMAIN answer is returned. Forwarding is not used. Example 6.1. Example Scenario The IdM server is authoritative for the test.example. DNS zone. BIND is configured to forward queries to the DNS server with the 192.0.2.254 IP address. When a client sends a query for the nonexistent.test.example. DNS name, BIND detects that the IdM server is authoritative for the test.example. zone and does not forward the query to the 192.0.2.254. server. As a result, the DNS client receives the NXDomain error message, informing the user that the queried domain does not exist. 6.3. Adding a global forwarder in the IdM Web UI Follow this procedure to add a global DNS forwarder in the Identity Management (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 In the IdM Web UI, select Network Services DNS Global Configuration DNS . In the DNS Global Configuration section, click Add . Specify the IP address of the DNS server that will receive forwarded DNS queries. Select the Forward policy . Click Save at the top of the window. Verification Select Network Services DNS Global Configuration DNS . Verify that the global forwarder, with the forward policy you specified, is present and enabled in the IdM Web UI. 6.4. Adding a global forwarder in the CLI Follow this procedure to add a global DNS forwarder by using the command line interface (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. Verification Use the dnsconfig-show command to display global forwarders. 6.5. Adding a DNS Forward Zone in the IdM Web UI 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 In the IdM Web UI, select Network Services DNS Forward Zones DNS . In the DNS Forward Zones section, click Add . In the Add DNS forward zone window, specify the forward zone name. Click the Add button and specify the IP address of a DNS server to receive the forwarding request. You can specify multiple forwarders per forward zone. Select the Forward policy . Click Add at the bottom of the window to add the new forward zone. Verification In the IdM Web UI, select Network Services DNS Forward Zones DNS . Verify that the forward zone you created, with the forwarders and forward policy you specified, is present and enabled in the IdM Web UI. 6.6. Adding a DNS Forward Zone in the CLI Follow this procedure to add a DNS forward zone by using the command line interface (CLI). 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 as IdM administrator. You know the Internet Protocol (IP) address of the DNS server to forward queries to. Procedure Use the dnsforwardzone-add command to add a new forward zone. Specify at least one forwarder with the --forwarder option if the forward policy is not none , and specify the forward policy with the --forward-policy option. Verification Use the dnsforwardzone-show command to display the DNS forward zone you just created. 6.7.
