Tutorial: Azure Active Directory single sign-on (SSO) integration with Zscaler
In this tutorial, you'll learn how to integrate Zscaler with Azure Active Directory (Azure AD). When you integrate Zscaler with Azure AD, you can:
- Control in Azure AD who has access to Zscaler.
- Enable your users to be automatically signed-in to Zscaler with their Azure AD accounts.
- Manage your accounts in one central location - the Azure portal.
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 single sign-on (SSO) enabled subscription.
In this tutorial, you configure and test Azure AD SSO in a test environment.
- Zscaler supports SP initiated SSO
- Zscaler supports Just In Time user provisioning
Adding Zscaler from the gallery
To configure the integration of Zscaler into Azure AD, you need to add Zscaler from the gallery to your list of managed SaaS apps.
- Sign in to the Azure portal using either a work or school account, or a personal Microsoft account.
- On the left navigation pane, select the Azure Active Directory service.
- Navigate to Enterprise Applications and then select All Applications.
- To add new application, select New application.
- In the Add from the gallery section, type Zscaler in the search box.
- Select Zscaler 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
Configure and test Azure AD SSO with Zscaler 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.
To configure and test Azure AD SSO with Zscaler, perform the following steps:
- Configure Azure AD SSO - to enable your users to use this feature.
- Configure Zscaler SSO - to configure the Single Sign-On settings on application side.
- Create Zscaler test user - to have a counterpart of B.Simon in Zscaler that is linked to the Azure AD representation of user.
- Test SSO - to verify whether the configuration works.
Configure Azure AD SSO
Follow these steps to enable Azure AD SSO in the Azure portal.
