Tutorial: Azure Active Directory integration with Zscaler One

In this tutorial, you'll learn how to integrate Zscaler One with Azure Active Directory (Azure AD). When you integrate Zscaler One with Azure AD, you can:

• Control in Azure AD who has access to Zscaler One.
• Enable your users to be automatically signed-in to Zscaler One with their Azure AD accounts.
• Manage your accounts in one central location - the Azure portal.

Prerequisites

To get started, you need the following items:

• An Azure AD subscription. If you don't have a subscription, you can get a free account.
• Zscaler One single sign-on (SSO) enabled subscription.

Scenario description

In this tutorial, you configure and test Azure AD single sign-on in a test environment.

• Zscaler One supports SP initiated SSO.

• Zscaler One supports Just In Time user provisioning.

Note

Identifier of this application is a fixed string value so only one instance can be configured in one tenant.

Add Zscaler One from the gallery

To configure the integration of Zscaler One into Azure AD, you need to add Zscaler One from the gallery to your list of managed SaaS apps.

1. Sign in to the Azure portal using either a work or school account, or a personal Microsoft account.
2. On the left navigation pane, select the Azure Active Directory service.
3. Navigate to Enterprise Applications and then select All Applications.
4. To add new application, select New application.
5. In the Add from the gallery section, type Zscaler One in the search box.
6. Select Zscaler One from results panel and then add the app. Wait a few seconds while the app is added to your tenant.

Configure and test Azure AD SSO for Zscaler One

Configure and test Azure AD SSO with Zscaler One using a test user called B.Simon. For SSO to work, you need to establish a link relationship between an Azure AD user and the related user in Zscaler One.

To configure and test Azure AD SSO with Zscaler One, perform the following steps:

1. Configure Azure AD SSO - to enable your users to use this feature.
   1. Create an Azure AD test user - to test Azure AD single sign-on with Britta Simon.
   2. Assign the Azure AD test user - to enable Britta Simon to use Azure AD single sign-on.
2. Configure Zscaler One SSO - to configure the Single Sign-On settings on application side.
   1. Create Zscaler One test user - to have a counterpart of Britta Simon in Zscaler One that is linked to the Azure AD representation of user.
3. Test SSO - to verify whether the configuration works.

Configure Azure AD SSO

Follow these steps to enable Azure AD SSO in the Azure portal.

1. In the Azure portal, on the Zscaler One application integration page, find the Manage section and select single sign-on.
