|   | In IDM 7.5.1 and later, the embedded Jetty web server supports Jetty 12.When serving SSL requests, Jetty 12 checks that the incoming host header matches the server certificate's subject and returns a `400 Bad Request` error on a mismatch. If you're upgrading to IDM 7.5.1 or later, you must ensure your IDM server certificate subject matches the host name used by your deployment.Learn more in [What's new](../release-notes/whats-new.html#jetty-12-support-751). |

By default, the embedded Jetty server uses the following settings:

* The HTTP, SSL, and Mutual Authentication ports defined in IDM.

* The same keystore and truststore settings as IDM.

* Trivial sample realm, `openidm/security/realm.properties` to add users.

The default settings are intended for evaluation only. Adjust them according to your production requirements.
