  • 5 min. za čitanje

In this tutorial, you'll learn how to integrate Sentry with Azure Active Directory (Azure AD). When you integrate Sentry with Azure AD, you can:

  • Control in Azure AD who has access to Sentry.
  • Enable your users to be automatically signed-in to Sentry with their Azure AD accounts.
  • Manage your accounts in one central location - the Azure portal.

Prerequisites

To get started, you need the following items:

  • An Azure AD subscription. If you don't have a subscription, you can get a free account.
  • Sentry single sign-on (SSO) enabled subscription.

Scenario description

In this tutorial, you configure and test Azure AD SSO in a test environment.

  • Sentry supports SP and IDP initiated SSO
  • Sentry supports Just In Time user provisioning

To configure the integration of Sentry into Azure AD, you need to add Sentry from the gallery to your list of managed SaaS apps.

  1. Sign in to the Azure portal using either a work or school account, or a personal Microsoft account.
  2. On the left navigation pane, select the Azure Active Directory service.
  3. Navigate to Enterprise Applications and then select All Applications.
  4. To add new application, select New application.
  5. In the Add from the gallery section, type Sentry in the search box.
  6. Select Sentry from results panel and then add the app. Wait a few seconds while the app is added to your tenant.

Configure and test Azure AD SSO for Sentry

Configure and test Azure AD SSO with Sentry using a test user called B.Simon. For SSO to work, you need to establish a link relationship between an Azure AD user and the related user in Sentry.

To configure and test Azure AD SSO with Sentry, perform the following steps:

  1. Configure Azure AD SSO - to enable your users to use this feature.
  2. Configure Sentry SSO - to configure the single sign-on settings on application side.
    • Create Sentry test user - to have a counterpart of B.Simon in Sentry that is linked to the Azure AD representation of user.
  3. Test SSO - to verify whether the configuration works.

Configure Azure AD SSO

Follow these steps to enable Azure AD SSO in the Azure portal.

  1. In the Azure portal, on the Sentry application integration page, find the Manage section and select single sign-on.

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

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

    Edit Basic SAML Configuration

  4. On the Basic SAML Configuration section, if you wish to configure the application in IDP initiated mode, enter the values for the following fields:

    a. In the Identifier text box, type a URL using the following pattern: https://sentry.io/saml/metadata/<ORGANIZATION_SLUG>/

    b. In the Reply URL text box, type a URL using the following pattern: https://sentry.io/saml/acs/<ORGANIZATION_SLUG>/

  5. Click Set additional URLs and 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://sentry.io/organizations/<ORGANIZATION_SLUG>/

    Note

    These values are not real. Update these values with the actual values Identifier, Reply URL, and Sign-on URL. For more information about finding these values, see the Sentry documentation. You can also refer to the patterns shown in the Basic SAML Configuration section in the Azure portal.

  6. On the Set up single sign-on with SAML page, in the SAML Signing Certificate section, click the copy icon to copy the App Metadata URL value, and then save it on your computer.

Create an Azure AD test user

In this section, you'll create a test user called B.Simon in the Azure portal.

  1. From the left pane in the Azure portal, select Azure Active Directory, select Users, and then select All users.
  2. Select New user at the top of the screen.
  3. In the User properties, follow these steps:
    1. In the Name field, enter B.Simon.
    2. In the User name field, enter the username@companydomain.extension. For example, B.Simon@contoso.com.
    3. Select the Show password check box, and then write down the value that's displayed in the Password box.
    4. Click Create.

Assign the Azure AD test user

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

  1. In the Azure portal, select Enterprise Applications, and then select All applications.
  2. In the applications list, select Sentry.
  3. In the app's overview page, find the Manage section and select Users and groups.
  4. Select Add user, then select Users and groups in the Add Assignment dialog.
  5. In the Users and groups dialog, select B.Simon from the Users list, then click the Select button at the bottom of the screen.
  6. 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.
  7. In the Add Assignment dialog, click the Assign button.

Configure Sentry SSO

To configure single sign-on on the Sentry side, go to Org Settings > Auth (or go to https://sentry.io/settings/<YOUR_ORG_SLUG>/auth/) and select Configure for Active Directory. Paste the App Federation Metadata URL from your Azure SAML configuration.

Create Sentry test user

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

Test SSO

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

SP initiated:

  1. In the Azure portal, select Test this application. You're redirected to the Sentry sign-on URL, where you can initiate the sign-in flow.

  2. Go to Sentry sign-on URL directly and initiate the sign-in flow from there.

IDP initiated:

  • In the Azure portal, select Test this application. You should be automatically signed in to the Sentry application for which you set up the SSO.

Either mode:

You can use the My Apps portal to test the application in any mode. When you click the Sentry tile in the My Apps portal, if configured in SP mode, you are redirected to the application sign-on page to initiate the sign-in flow. If configured in IDP mode, you should be automatically signed in to the Sentry application for which you set up the SSO. For more information about the My Apps portal, see Sign in and start apps from the My Apps portal.

Next steps

Once you configure Sentry 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.
