Create S4 - Digitsec test user

In this section, a user called B.Simon is created in S4 - Digitsec. S4 - Digitsec supports just-in-time user provisioning, which is enabled by default. There is no action item for you in this section. If a user doesn't already exist in S4 - Digitsec, a new one is created after authentication.

Test SSO

In this section, you test your Microsoft Entra single sign-on configuration with following options.

SP initiated:

  • Click on Test this application, this will redirect to S4 - Digitsec Sign on URL where you can initiate the login flow.

  • Go to S4 - Digitsec Sign-on URL directly and initiate the login flow from there.

IDP initiated:

  • Click on Test this application, and you should be automatically signed in to the S4 - Digitsec for which you set up the SSO.

You can also use Microsoft My Apps to test the application in any mode. When you click the S4 - Digitsec tile in the My Apps, if configured in SP mode you would be redirected to the application sign-on page for initiating the login flow and if configured in IDP mode, you should be automatically signed in to the S4 - Digitsec for which you set up the SSO. For more information about the My Apps, see Introduction to the My Apps.
