红帽全球峰会29.7. DoT configuration options for ipa-server-install and ipa-dns-install
Learn about the available configuration options for enabling eDNS in your IdM deployment. You can use the same options to enable eDNS during a new IdM server installation using the ipa-server-install or to modify an existing installation using the ipa-dns-install command.
-
--dns-over-tlsenables DoT -
--dot-forwarderspecifies upstream DoT servers using the--dot-forwarder <server_ip_1>#<dns_server_hostname_1> --dot-forwarder <server_ip_2>#<dns_server_hostname_2>format. For example, ifdot.dns.example.comis the name of your upstream DoT server and 198.51.100.143 is its IP address, set--dot-forwarderto198.51.100.143#dot.dns.example.com. -
--dns-over-tls-keyand--dns-over-tls-certto configure custom keys and certificates --dns-policysets the DNS security policy-
--dns-policy=relaxedallows both encrypted (DoT) and unencrypted DNS queries. The system attempts to use DoT but falls back to unencrypted DNS if DoT is unavailable. This is the default policy. -
--dns-policy=enforcedrequires only encrypted DNS communication. The system strictly enforces DoT, and rejects any DNS resolution that does not support encryption, including discovery from IdM clients and replicas.

For more details about the configuration options see the DNS OPTIONS section in the ipa-server-install(1) and the ipa-dns-install(1) man page on your system.
