Configure and test Microsoft Entra SSO for EY GlobalOne

Configure and test Microsoft Entra SSO with EY GlobalOne using a test user called B. Simon. For SSO to work, you need to establish a link relationship between a Microsoft Entra user and the related user in EY GlobalOne.

To configure and test Microsoft Entra SSO with EY GlobalOne, perform the following steps:

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 EY GlobalOne SSO to configure the SSO settings on application side.
   1. Create EY GlobalOne test user to have a counterpart of B. Simon in EY GlobalOne that is linked to the Microsoft Entra representation of user.
3. Test SSO to verify whether the configuration works.

Configure EY GlobalOne SSO

To configure single sign-on on EY GlobalOne side, you need to send the downloaded Certificate (Raw) and appropriate copied URLs from the application configuration to EY GlobalOne support team. They set this setting to have the SAML SSO connection set properly on both sides.

Create EY GlobalOne test user

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

• Go to EY GlobalOne 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 EY GlobalOne 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 EY GlobalOne 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 EY GlobalOne for which you set up the SSO. For more information, see Microsoft Entra My Apps.

Once you configure EY GlobalOne you can enforce session control, which protects exfiltration and infiltration of your organization’s sensitive data in real time. Session control extends from Conditional Access. Learn how to enforce session control with Microsoft Defender for Cloud Apps.
