Tutorial: Microsoft Entra SSO integration with Dagster Cloud

  • Alt

In this tutorial, you'll learn how to integrate Dagster Cloud with Microsoft Entra ID. When you integrate Dagster Cloud with Microsoft Entra ID, you can:

  • Control in Microsoft Entra ID who has access to Dagster Cloud.
  • Enable your users to be automatically signed-in to Dagster Cloud with their Microsoft Entra accounts.
  • Manage your accounts in one central location.

Prerequisites

To get started, you need the following items:

  • A Microsoft Entra subscription. If you don't have a subscription, you can get a free account.
  • Dagster Cloud single sign-on (SSO) enabled subscription.

Scenario description

In this tutorial, you configure and test Microsoft Entra SSO in a test environment.

  • Dagster Cloud supports SP and IDP initiated SSO.
  • Dagster Cloud supports Just In Time user provisioning.
  • Dagster Cloud supports Automated user provisioning.

To configure the integration of Dagster Cloud into Microsoft Entra ID, you need to add Dagster Cloud from the gallery to your list of managed SaaS apps.

  1. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.
  2. Browse to Identity > Applications > Enterprise applications > New application.
  3. In the Add from the gallery section, type Dagster Cloud in the search box.
  4. Select Dagster Cloud from results panel and then add the app. Wait a few seconds while the app is added to your tenant.

Alternatively, you can also use the Enterprise App Configuration Wizard. In this wizard, you can add an application to your tenant, add users/groups to the app, assign roles, as well as walk through the SSO configuration as well. Learn more about Microsoft 365 wizards.

Configure and test Microsoft Entra SSO for Dagster Cloud

Configure and test Microsoft Entra SSO with Dagster Cloud 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 Dagster Cloud.

To configure and test Microsoft Entra SSO with Dagster Cloud, 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 Dagster Cloud SSO - to configure the single sign-on settings on application side.
    1. Create Dagster Cloud test user - to have a counterpart of B.Simon in Dagster Cloud that is linked to the Microsoft Entra representation of user.
  3. Test SSO - to verify whether the configuration works.

Configure Microsoft Entra SSO

Follow these steps to enable Microsoft Entra SSO.

  1. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.

  2. Browse to Identity > Applications > Enterprise applications > Dagster Cloud > Single sign-on.

  3. On the Select a single sign-on method page, select SAML.

  4. On the Set up single sign-on with SAML page, click the pencil icon for Basic SAML Configuration to edit the settings.

    b. In the Reply URL text box, type a URL using the following pattern: https://<ORGANIZATION_NAME>.dagster.cloud/auth/saml/consume

  6. Perform the following step, if you wish to configure the application in SP initiated mode:

    In the Sign on URL text box, type a URL using the following pattern: https://<ORGANIZATION_NAME>.dagster.cloud/auth/saml/login

    Note

    These values are not real. Update these values with the actual Identifier, Reply URL and Sign-on URL. You can refer to the patterns shown in the Basic SAML Configuration section. See Dagster Cloud's documentation for more information.

  7. Dagster Cloud application expects the SAML assertions in a specific format, which requires you to add custom attribute mappings to your SAML token attributes configuration. The following screenshot shows the list of default attributes.

Configure Dagster Cloud SSO

To configure single sign-on on the Dagster Cloud side, you need to upload the Federation Metadata XML file to Dagster Cloud using the dagster-cloud CLI.

Create Dagster Cloud test user

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

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

Next steps

Once you configure Dagster Cloud 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.
