Tutorial: Microsoft Entra single sign-on (SSO) integration with Blink

  • Artikkeli

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

  • Control in Microsoft Entra ID who has access to Blink.
  • Enable your users to be automatically signed-in to Blink 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.
  • Blink single sign-on (SSO) enabled subscription.

Scenario description

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

To configure the integration of Blink into Microsoft Entra ID, you need to add Blink 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 Blink in the search box.
  4. Select Blink 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 with Blink 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 Blink.

To configure and test Microsoft Entra SSO with Blink, 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 Blink SSO - to configure the Single Sign-On settings on application side.
    1. Create Blink test user - to have a counterpart of B.Simon in Blink 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 > Blink > 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.

  5. On the Basic SAML Configuration section, enter the values for the following fields:

    1. In the Sign on URL text box, type a URL using one of the following patterns:
    Sign-on URL

    https://<SUBDOMAIN>.joinblink.com
    1. In the Identifier (Entity ID) text box, type a URL using the following pattern:

    https://api.joinblink.com/saml/o-<TENANTID>

    Note

    These values are not real. Update these values with the actual Sign on URL and Identifier. Contact Blink Client support team to get these values. You can also refer to the patterns shown in the Basic SAML Configuration section.

  6. Blink Meetings 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. Click Edit icon to open User Attributes dialog.

    first_name user.givenname
    second_name user.surname
    email user.mail

    1. Click Add new claim to open the Manage user claims dialog.

    2. In the Name textbox, type the attribute name shown for that row.

    3. Leave the Namespace blank.

    4. Select Source as Attribute.

    5. From the Source attribute list, type the attribute value shown for that row.

    6. Click Save.

  8. On the Set up Single Sign-On with SAML page, in the SAML Signing Certificate section, find Federation Metadata XML and select Download to download the certificate and save it on your computer.

Create a Microsoft Entra test user

In this section, you'll create a test user called B.Simon.

  1. Sign in to the Microsoft Entra admin center as at least a User Administrator.
  2. Browse to Identity > Users > All users.
  3. Select New user > Create new user, at the top of the screen.

    3. Select the Show password check box, and then write down the value that's displayed in the Password box.
    4. Select Review + create.
  5. Select Create.

Assign the Microsoft Entra test user

In this section, you'll enable B.Simon to use single sign-on by granting access to Blink.

  1. Sign in to the Microsoft Entra admin center as at least a Cloud Application Administrator.
  2. Browse to Identity > Applications > Enterprise applications > Blink.
  3. In the app's overview page, select Users and groups.
  4. Select Add user/group, then select Users and groups in the Add Assignment dialog.
    1. In the Users and groups dialog, select B.Simon from the Users list, then click the Select button at the bottom of the screen.
    2. If you are expecting a role to be assigned to the users, you can select it from the Select a role dropdown. If no role has been set up for this app, you see "Default Access" role selected.
    3. In the Add Assignment dialog, click the Assign button.

To configure single sign-on on Blink side, you need to send the downloaded Federation Metadata XML and appropriate copied URLs from the application configuration to Blink support team. They set this setting to have the SAML SSO connection set properly on both sides.

In this section, a user called Britta Simon is created in Blink. Blink 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 Blink, a new one is created after authentication.

Blink also supports automatic user provisioning, you can find more details here on how to configure automatic user provisioning.

Test SSO

In this section, you test your Microsoft Entra single sign-on configuration with following options.

  • Click on Test this application, this will redirect to Blink Sign-on URL where you can initiate the login flow.

  • Go to Blink Sign-on URL directly and initiate the login flow from there.

  • You can use Microsoft My Apps. When you click the Blink tile in the My Apps, this will redirect to Blink Sign-on URL. For more information, see Microsoft Entra My Apps.

Next steps

Once you configure Blink 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.
