Dropbox Integration with AuthPoint

Deployment Overview

This document describes how to set up multi-factor authentication (MFA) for Dropbox with AuthPoint as an identity provider. Dropbox must already be configured and deployed before you set up MFA with AuthPoint.

Dropbox can be configured to support MFA in several modes. For this integration, we set up SAML with AuthPoint.

Dropbox Authentication Data Flow with AuthPoint

AuthPoint communicates with various cloud-based services and service providers with the SAML protocol. This diagram shows the data flow of an MFA transaction for Dropbox.

Before You Begin

Before you begin these procedures, make sure that:

  • End-users can use Dropbox
  • A token is assigned to a user in AuthPoint
  • You have an AuthPoint identity provider (IdP) certificate

Configure Dropbox

To start, you must download the metadata file and the certificate file from the Resources page in the AuthPoint management UI. Once you have those, you can configure Dropbox.

From the WatchGuard Cloud web UI:

  1. From the navigation menu, select Configure > AuthPoint. If you have a Service Provider account, you must first pivot to your Subscriber view.
  2. Select Resources.
  3. Click Certificate.

  1. Next to AuthPoint certificate you will associate with your resource, click and select Download Metadata and Download Certificate.

    We recommend that you choose the certificate with the latest expiration date.

    The AuthPoint metadata provides your resource, in this case Dropbox, with information necessary to identify AuthPoint as a trusted identity provider.

  1. Sign in Dropbox Business as an administrator.
  2. Select Admin Console.

  1. Select Settings.
  2. In the Authentication section, click Single sign-on.

  1. From the drop-down list, select Optional or Required.

  1. Open the AuthPoint metadata file you downloaded and find the SingleSignOnService Location value.
  2. Click Add sign-in URL and paste the SingleSignOnService Location value from the AuthPoint metadata file.
  3. Click Upload certificate and upload the AuthPoint certificate file you downloaded.

  1. Click Apply Changes.

Configure AuthPoint

Before AuthPoint can receive authentication requests from Dropbox, you must specify the Dropbox client as a SAML resource in AuthPoint. You must also assign the Dropbox resource to the user group that will authenticate through Dropbox.

Add a SAML Resource in AuthPoint

From the AuthPoint management UI:

  1. From the navigation menu, select Resources.
  2. From the Choose a Resource Type drop-down list, select SAML. Click Add Resource.

  1. In the Application Type drop-down list, select Dropbox.
  2. In the Service Provider Entity ID text box, type Dropbox.
  3. In the Assertion Consumer Service text box, type https://www.dropbox.com/saml_login.
  4. Click Save.

Add an Access Policy to AuthPoint

You must have at least one user group in AuthPoint for authentication with Dropbox, and you must assign an access policy for the Dropbox resource to that group. If you already have a group, you do not have to add another group.

In the AuthPoint management UI:

  1. From the navigation menu, select Groups.
  2. To add a new group, click Add Group. If you already have a group that you want to use, select the group to edit it.

  1. In the Name text box, type a descriptive name for the group.
  2. (Optional) In the Description text box, type a description of the group.

  1. In the Access Policy section, click Add Policy.

  1. In the Add Policy dialog box, from the Resource drop-down list, select the resource you want to add an access policy for.
  2. (Optional) To require that users type their password before they authenticate for this resource, select the Require Password Authentication slider.
  3. Select the authentication options that users in this group can choose from when they authenticate.

    For SAML resources, if you select more than one authentication option, users must choose one of the available options when they authenticate. For example, if you select OTP and Push, users can choose to type their OTP or approve a push to authenticate. You cannot require that they do both.

  1. Click Add.

  1. (Optional) Add one or more safe locations to your group. For more information about safe locations and detailed instructions to add them, see About Safe Locations.
  2. Click Save.

Before you assign users to a group, you must add them to AuthPoint. You can manually add user accounts or import user accounts from your LDAP database. For more information on how to add user accounts, see Add User Accounts.

Test the Integration

To test the integration of AuthPoint and configuration of your Dropbox, you can authenticate with a mobile token on your mobile device. You can choose any method (one-time password, QR code, or push).

In this example, we show the push authentication method (users receive a push notification in the mobile app that they must approve to authenticate).

  1. In a web browser, go to the Dropbox URL.
  2. Type your email address or AuthPoint user name. Click Next.
  3. If required, in the Password text box, type your password.
  4. For the authentication method, select Push.
  5. Click Send.
  6. Approve the authentication request that is sent to your mobile device.
    You are logged in to Dropbox.
