Microsoft Entra SSO integration with Island

In this article, you learn how to integrate Island with Microsoft Entra ID. Microsoft Entra single sign-on enables end-users to directly access Island, The Enterprise Browser, via Microsoft Entra authentication. Admins can add or remove users and update attributes from Microsoft Entra ID as well. When you integrate Island with Microsoft Entra ID, you can:

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

You'll configure and test Microsoft Entra single sign-on for Island in a test environment. Island supports both SP and IDP initiated single sign-on and Just In Time user provisioning.

Prerequisites

To integrate Microsoft Entra ID with Island, you need:

Add application and assign a test user

Before you begin the process of configuring single sign-on, you need to add the Island application from the Microsoft Entra gallery. You need a test user account to assign to the application and test the single sign-on configuration.

Add Island from the Microsoft Entra application gallery to configure single sign-on with Island. For more information on how to add application from the gallery, see the Quickstart: Add application from the gallery.

Create and assign Microsoft Entra test user

Follow the guidelines in the create and assign a user account article to create a test user account called B.Simon.

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, and assign roles. The wizard also provides a link to the single sign-on configuration pane. Learn more about Microsoft 365 wizards..

Configure Microsoft Entra SSO

Complete the following steps to enable Microsoft Entra single sign-on.

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

  2. Browse to Identity > Applications > Enterprise applications > Island > 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, select the pencil icon for Basic SAML Configuration to edit the settings.

    Screenshot shows how to edit Basic SAML Configuration.

  5. On the Basic SAML Configuration section, perform the following steps:

    a. In the Identifier textbox, type a URL using the following pattern: urn:auth0:za-production:<TENANTID>-saml-browser-prod

    b. In the Reply URL textbox, type a URL using the following pattern: https://login.island.io/login/callback?connection=<TENANTID>-saml-browser-prod

  6. If you wish to configure the application in SP initiated mode, then perform the following step:

    In the Sign on URL textbox, type the URL: https://download.island.io

    Note

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

  7. Your Island 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 an example for this. The default value of Unique User Identifier is user.userprincipalname but Island expects this to be mapped with the user's object ID and change the name identifier format setting to Persistent. For that you can use user.objectid attribute from the list or use the appropriate attribute value based on your organization configuration.

    Screenshot shows the image of attributes configuration.

    Note

    From the list of default attributes, please edit the following claims manually:

    1. Click the givenname (user.givenname) claim, change the Name setting to given_name and click Save.
    2. Click the name (user.userprincipalname) claim, change the Source setting to Transformation and edit the Manage transformation settings as follows.
    3. Select Transformation, choose Join(). Select user.givenname as Parameter 1 and add a single whitespace as Separator and choose user.surname as Parameter 2.
    4. Click Add and Save to complete the configuration.
  8. In addition to above, Island application expects few more attributes to be passed back in SAML response, which are shown below. These attributes are also pre populated but you can review them as per your requirements.

    Name Source Attribute
    email user.mail
    family_name user.surname
    groups user.groups [All]
  9. On the Set up single sign-on with SAML page, in the SAML Signing Certificate section, find Certificate (Base64) and select Download to download the certificate and save it on your computer.

    Screenshot shows the Certificate download link.

  10. On the Set up Island section, copy the appropriate URL(s) based on your requirement.

    Screenshot shows to copy configuration appropriate URL.

Configure Island SSO

To configure single sign-on on Island side, you need to send the downloaded Certificate (Base64) and appropriate copied URLs from the application configuration to Island support team. They set this setting to have the SAML SSO connection set properly on both sides.

Create Island test user

In this section, a user called B.Simon is created in Island. Island supports just-in-time user provisioning, which is enabled by default. There's no action item for you in this section. If a user doesn't already exist in Island, a new one is commonly 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 Island Sign-on URL where you can initiate the login flow.

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

Once you configure Island 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 Cloud App Security.
