Duo Protection for Tableau Online

Duo offers a variety of methods for adding two-factor authentication and flexible security policies to Tableau Online SSO logins, complete with inline self-service enrollment and authentication prompt.

These are instructions for Tableau Online only. Click here for Tableau Server.

Tableau Online requires Duo Access Gateway version 1.3.1 or greater. Please upgrade your Duo Access Gateway before attempting to use Tableau Online.

Overview

As business applications move from on-premises to cloud hosted solutions, users experience password fatigue due to disparate logons for different applications. Single sign-on (SSO) technologies seek to unify identities across systems and reduce the number of different credentials a user has to remember or input to gain access to resources.

While SSO is convenient for users, it presents new security challenges. If a user's primary password is compromised, attackers may be able to gain access to multiple resources. In addition, as sensitive information makes its way to cloud-hosted services it is even more important to secure access by implementing two-factor authentication.

Duo Access Gateway

Duo Access Gateway (DAG), our on-premises SSO product, layers Duo's strong authentication and flexible policy engine on top of Tableau logins using the Security Assertion Markup Language (SAML) 2.0 authentication standard. Duo Access Gateway authenticates your users using existing on-premises or cloud-based directory credentials and prompts for two-factor authentication before permitting access to Tableau.

Duo Access Gateway is part of the Duo Beyond and Duo Access plans, so you can define policies that enforce unique controls for each individual SSO application. For example, you can require that Salesforce users complete two-factor authentication at every login, but only once every seven days when accessing Tableau. Duo checks the user, device, and network against an application's policy before allowing access to the application.

Deploy Duo Access Gateway

  1. Install Duo Access Gateway on a server in your DMZ. Follow our instructions for deploying the server, configuring DAG settings, and adding an Authentication Source.

  2. Add the attributes from the table below that correspond to the Duo attributes Mail attribute, Last name attribute, and First name attribute in the "Attributes" field when configuring your Active Directory or OpenLDAP authentication source in the DAG admin console, separated by a comma. For example, if Active Directory is your authentication source, enter mail,sn,givenName in the "Attributes" field.

    Duo Attribute Active Directory OpenLDAP
    Mail attribute mail mail
    First name attribute givenName gn
    Last name attribute sn sn

    If your organization uses other directory attributes than the ones listed here then enter those attribute names instead. If you've already configured the attributes list for another cloud service provider, append these additional attributes to the list.

  3. After completing the initial DAG configuration steps, click Applications on the left side of the Duo Access Gateway admin console.

  4. Scroll down the Applications page to the Metadata section. This is the information you need to provide to Datadog when configuring SSO. Click the Download XML metadata link to obtain the DAG metadata file (the downloaded file is named "dag.xml").

Configure Tableau Online SSO

Add the Duo Access Gateway as a new single sign-on provider for Tableau Online.

  1. Log into your Tableau Online account as an administrative user.

  2. Click Settings at the top of the Tableau Online page. Once on the "Settings" page click the Authentication tab.

  3. Under "Authentication Types" check the box next to Single sign-on with SAML. New options will appear.

  4. In "1 Export metadata from Tableau Online" locate the Tableau Online entity ID. Copy the information after "alias="; you will need this later.

    Example: If the Entity ID is https://sso.online.tableau.com/public/sp/metadata?alias=12ab3456-89b4-4444-8956-0b0ccb870954 you will want to copy 12ab3456-89b4-4444-8956-0b0ccb870954.

  5. In "4 Import metadata file into Tableau Online" click Browse.. next to IdP metadata file. Select the dag.xml file you downloaded earlier and then click Apply. Information will be automatically loaded into the next two fields.

  6. In "5 Match attributes" fill out the fields with information from the table below:

    Tableau Field IdP Field
    Email mail
    Display Name: First name User.FirstName
    Display Name: Last name User.LastName

    Click Apply once you've filled out all the required fields.

Create the Tableau Online Application in Duo

  1. Log on to the Duo Admin Panel and navigate to Applications.

  2. Click Protect an Application, locate SAML - Tableau Online in the applications list, and click Protect this Application. See Getting Started for help.

  3. The Alias is the the Tableau Online Entity ID alias value you made note of earlier.

  4. Tableau Online uses the Mail attribute, First name attribute, and Last name attribute when authenticating. We've mapped those to DAG supported authentication source attributes as follows:

    Duo Attribute Active Directory OpenLDAP SAML IdP Google Azure
    Mail attribute mail mail mail email mail
    First name attribute givenName gn givenName given_name givenName
    Last name attribute sn sn sn family_name surname

    If you are using non-standard attributes for your authentication source, check the Custom attributes box and enter the names of the attributes you wish to use instead.

  5. Click Save Configuration when done.

    Duo Tableau Application Settings

  6. You can adjust additional settings for your new SAML application at this time — like changing the application's name from the default value, enabling self-service, or assigning a group policy — or come back and change the application's policies and settings after you finish SSO setup. If you do update any settings, click the Save Changes button when done.

  7. Click the Download your configuration file link to obtain the Tableau application settings (as a JSON file).

    Important: This file contains information that uniquely identifies this application to Duo. Secure this file as you would any other sensitive or password information. Don't share it with unauthorized individuals or email it to anyone under any circumstances!

Add the Tableau Online Application to Duo Access Gateway

  1. Return to the Applications page of the DAG admin console session.

  2. Click the Choose File button in the "Add Application" section of the page and locate the Tableau Online SAML application JSON file you downloaded from the Duo Admin Panel earlier. Click the Upload button after selecting the JSON configuration file.

  3. The Tableau Online SAML application is added.

Log in with SSO

If your organization enabled the Duo Access Gateway portal, log into the portal page using the link provided by your administrator. Click Tableau Online from the dashboard to access the application.

You can also access Tableau Online by going to the Tableau Online login page, entering your e-mail address, and clicking Sign In. This redirects to the Duo Access Gateway login page. Enter your Authentication Source logon information, approve Duo two-factor authentication, and get redirected back to the Tableau site after authenticating.

DAG Login and Authentication Prompt

Congratulations! Your Tableau users now authenticate using Duo Access Gateway.

Microsoft AD FS

Microsoft's Active Directory Federation Services (AD FS) is a popular choice for SSO because it easily integrates with the AD identity store many organizations already have deployed. Duo's support for cloud applications and SSO drops in to an existing AD FS installation to provide secondary authentication after a user passes primary authentication (successful Active Directory logon).

If you don't already have AD federation running the first step is to install and configure Microsoft AD FS in your organization. Microsoft's Deployment Guides for AD FS versions 2.0, 2.1, and 3.0 are available on the TechNet site.

Once your AD FS services are up and running, the second step is to configure the SSO partnership between your AD FS service and the external cloud resource, in this case Tableau. Learn more about configuring Tableau SSO with AD FS at the Tableau Online Help site.

After you have successfully configured and tested AD FS SSO login to Tableau using your AD domain credentials, you can then install the Duo AD FS integration. AD FS protection is included with Duo's paid plans.

With the Duo integration for AD FS installed, users pass primary authentication to the AD FS service as usual. Once primary authentication succeeds, users are forwarded to the Duo service for secondary authentication. After approving logon using one of Duo's authentication methods, the user is fully logged in to Tableau.

Other Identity Partners

Using a third-party SSO provider for cloud application access? Duo partners with leading cloud SSO providers like Okta and OneLogin to secure access with our strong and flexible authentication platform.

You can also use Duo two-factor authentication with CAS and Shibboleth on-premises IdPs.
