Integrate Apache Kafka on Confluent Cloud

Confluent Cloud is a fully managed, cloud-native event streaming platform powered by Apache Kafka. See https://www.confluent.io/. You can configure your Confluent Cloud account for Single Sign-On (SSO) through Identity as a Service.

Note: This guide was tested using previous versions of Identity as a Service 5.34 and Confluent Cloud Trial version 7.2. Other versions of Confluent Cloud may require integration and configuration steps that differ from those documented in this procedure. For newer versions of Confluent Cloud, this integration guide may be used as an initial approach for integrating Confluent Cloud. In the event of other issues, contact support@entrust.com for assistance.

Before you begin, open two browser windows. In one window, log in to your Confluent Cloud administrator account. In the other window, log in to your IDaaS administrator account.

To integrate Confluent Cloud with Identity as a Service, you must do the following:

2. Click Add. The Select an Application Template page appears.

3. Do one of the following:

● Select SAML Cloud Integrations from the search drop-down list and scroll to find the application you want to add to IDaaS.

11. In the Service Provider Entity ID field, enter the Entity ID you copied Step 1: copy the Assertion Consumer Service URL and Entity ID from Confluent Cloud.

12. Leave the Single Logout Service URL field empty.

13. Enter the SAML Session Timeout to the time when the SAML Assertion times out. The maximum is 720 minutes.

14. Enter the Max Authentication Age (seconds) to set the maximum amount of time that can elapse before a user is required to reauthenticate during a new login attempt. This applies for both SP-initiated and IDP-initiated login. Set this field to -1 to disable this feature.
