Red Hat Summit29.4. Installing an IdM client configured to use eDNS
You can install an IdM client with DNS-over-TLS (DoT) enabled by performing the non-interactive installation. This setup applies the enforced DoT policy and requires the client to use eDNS queries exclusively.
Prerequisites
- Review the steps outlined in the Preparing the system for IdM client installation.
-
For
enforcedDoT, complete the steps in Configuring client and replica systems to use DoT exclusively. -
Ensure the
ipa-clientandipa-client-encrypted-dnspackages are installed.
Procedure
Install an IdM client with DoT enabled:
# ipa-client-install --domain <domain_name> --dns-over-tls -p admin --password <admin_password> -U
Verification
On the IdM client, review cat
/etc/unbound/unbound.conf:$ cat /etc/unbound/unbound.conf- Verify that the configuration contains the IP address and hostname of the IdM server.
Troubleshooting
On the IdM client, run a DNS query to trigger traffic:
$ dig <domain_name>- Review the logs on the IdM server to verify that the query was routed through DoT.
