1. Configure Microsoft Entra SSO - to enable your users to use this feature.
   1. Create a Microsoft Entra test user - to test Microsoft Entra single sign-on with B.Simon.
   2. Assign the Microsoft Entra test user - to enable B.Simon to use Microsoft Entra single sign-on.
2. Configure Neustar UltraDNS SSO - to configure the single sign-on settings on application side.
   1. Create Neustar UltraDNS test user - to have a counterpart of B.Simon in Neustar UltraDNS that is linked to the Microsoft Entra representation of user.

Create Neustar UltraDNS test user

In this section, a user called Britta Simon is created in Neustar UltraDNS. Neustar UltraDNS 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 Neustar UltraDNS, 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 Neustar UltraDNS Sign on URL where you can initiate the login flow.

• Go to Neustar UltraDNS 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 Neustar UltraDNS 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 Neustar UltraDNS 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 Neustar UltraDNS for which you set up the SSO. For more information about the My Apps, see Introduction to the My Apps.
