Microsoft Entra single sign-on (SSO) integration with Nuclino

In this article, you learn how to integrate Nuclino with Microsoft Entra ID. When you integrate Nuclino with Microsoft Entra ID, you can:

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

The scenario outlined in this article assumes that you already have the following prerequisites:

• One of the following roles:
  • Application Administrator
  • Cloud Application Administrator
  • Application Owner.

• Nuclino single sign-on (SSO) enabled subscription.

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

• Nuclino supports SP and IDP initiated SSO.

To configure the integration of Nuclino into Microsoft Entra ID, you need to add Nuclino 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 Nuclino in the search box.
4. Select Nuclino 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, and walk through the SSO configuration as well. Learn more about Microsoft 365 wizards.

Configure and test Microsoft Entra SSO with Nuclino 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 Nuclino.

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

Follow these steps to enable Microsoft Entra SSO.

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

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

• Select Test this application, this option redirects to Nuclino Sign on URL where you can initiate the login flow.

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

• Select Test this application, and you should be automatically signed in to the Nuclino for which you set up the SSO.

You can also use Microsoft My Apps to test the application in any mode. When you select the Nuclino 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 Nuclino for which you set up the SSO. For more information about the My Apps, see Introduction to the My Apps.

Once you configure Nuclino 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.
