Step 1:
Copy the SAML configurations from Identity as a ServiceSplunk SOAR (On-premises) is a Security Orchestration, Automation, and Response (SOAR) system (see Splunk SOAR Guided Product Tour). You can protect access to Splunk SOAR by integrating Splunk SOAR with Identity as a Service. Once integrated, users can use single sign-on to log in to their Splunk SOAR account through Identity as a Service.
Note: This integration was tested using Identity as a Service version 5.31 and Splunk SOAR August 2023 version. Other versions of Splunk SOAR may require integration and configuration steps that differ from those documented in this procedure. 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 Splunk SOAR administrator account. In the other window, log in to your IDaaS administrator account.
