Written by
Updated at October 17, 2024

You can use Microsoft Entra ID (formerly Azure Active Directory) to authenticate users in an organization.

To configure user group mapping in Entra ID and in an identity federation:

  1. Start configuring an application in Azure.
  2. Create a federation in Yandex Cloud Organization.
  3. Add the application's SAML certificate to the federation.
  4. Complete configuring the application.
  5. Configure group mapping on the application side.
  6. Configure group mapping on the federation side.
  7. Test the authentication operation.

Getting started

Make sure you have access to the following services on the Azure portal:

  • Enterprise applications.
  • Microsoft Entra ID.

Start configuring an application in Azure

The identity provider's (IdP) role is played by Microsoft Azure with Single Sign-On (SSO) configured. To create an application and begin configuring it:

  1. Go to the Azure portal.

  2. Under Azure services, select Enterprise applications.

  3. On the left-hand panel, select Enterprise applications → All applications.

  4. Click New application.

  5. On the Browse Microsoft Entra gallery page, click Create your own application.

  6. In the window that opens:

    1. Name your app, e.g., yandex-cloud-saml.
    2. Select Integrate any other application you don't find in the gallery.
    3. Click Create.

    You will be taken to your new app's page.

  7. In the left-hand panel, select Single sign-on.

  8. Select the SAML single sign-on.

    The SAML-based sign-on page will open.

  9. Download the application's SAML certificate used to sign messages from Entra ID:

    1. Find SAML certificates → Assertion signing certificate.
    2. Use the link in the Certificate (Base64) field to download the certificate.

  10. Save the credentials you will need later to configure your identity federation:

    1. Find the yandex-cloud-saml configuration section.

      If you have chosen a different application name, the section name will be different from the one provided.

    2. Save the following credentials:

      • Login page URL in the following format:

        https://login.microsoftonline.com/<tenant_ID>/saml2

      • Microsoft Entra ID in the following format:

        https://sts.windows.net/<tenant_ID>/

Note

The configuring of SAML-based sign-on for the application will continue after you create an identity federation.

Do not close the configuration tab in your browser.

Create a Yandex Cloud Organization federation

  1. Go to Yandex Cloud Organization.

  2. In the left-hand panel, select Federations .

  3. Click Create federation.

  4. Enter a name for the federation, e.g., demo-federation. It must be unique within the folder.

  5. You can also add a description, if required.

  6. In the Cookie lifetime field, specify the time before the browser asks the user to re-authenticate.

  7. In the IdP Issuer field, paste the Microsoft Entra ID you got when configuring the Azure app.

  8. In the Link to the IdP login page field, paste the login page URL you got when configuring the Azure app.

  9. Enable Automatically create users to automatically add a new user to your organization after authentication. Otherwise, you will need to manually add your federated users.

    A federated user is created automatically only when they log in to a cloud for the first time. If you removed a user from the federation, you can only add them back manually.

  10. (Optional) To make sure that all authentication requests from Yandex Cloud contain a digital signature, enable Sign authentication requests.

  11. Enable Mandatory re-authentication (ForceAuthn) in IdP to set true for the ForceAuthn parameter in a SAML authentication request. If enabled, the IdP will request the user to re-authenticate once the Yandex Cloud session expires.

  12. Click Create federation.

  13. Use the link in the Sign authentication requests field to download the certificate (if the option was enabled earlier).

    You will need this certificate later when configuring SAML-based sign-on for the Azure app.

Add the Azure app's SAML certificate to the federation

To enable Cloud Organization to verify the app's SAML certificate during authentication, add the certificate to the federation:

  1. Go to Yandex Cloud Organization.

  2. In the left-hand panel, navigate to Federations and select the federation to add the certificate to: demo-federation.

  3. At the bottom of the page, click Adding a certificate.

  4. Enter certificate name and description.

  5. Enable Text and paste the data of the certificate obtained earlier.

Complete the Azure app configuration

  1. Navigate to the browser tab on which you were configuring SAML-based sign-on for the yandex-cloud-saml application.

  2. Specify the redirect URL:

    1. Find the Basic SAML configuration section.

    2. In the section, click Edit.

    3. Specify the same redirect URL in both the ID (entity) and Response URL (assertion consumer service URL) fields.

      The redirect URL must be in the following format:

      https://console.cloud.yandex.ru/federations/<federation_ID>
      How to get the federation ID

      1. Go to Yandex Cloud Organization.

      2. In the left-hand panel, select Federations .

      3. Copy the ID of the federation you are configuring access for.

    4. Click Save in the right-hand panel.

  3. (Optional) If you enabled Sign authentication requests when creating a federation in Yandex Cloud Organization, add the federation certificate to the application:

    1. Find SAML certificates → Verification certificates (optional) and click Edit.
    2. Enable Require verification certificates.
    3. Click Send certificate.
    4. Upload the certificate in PEM format.
    5. Click Save in the right-hand panel.

    On successful authentication, the IdP server will redirect you to the URL (https://console.cloud.yandex.ru/federations/<federation_ID>) you specified in the SAML settings for the Azure app, and then to the management console home page.

  4. Make sure the signed in user belongs to yc-demo-group and has the viewer permissions for resources according to the role assigned to the group.
