Duo Protection for UserVoice with Duo Access Gateway

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 and zero-trust policies.

Duo Access Gateway

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

Duo Access Gateway is included in the Duo Premier, Duo Advantage, and Duo Essentials plans, which also include the ability to 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 UserVoice. Duo checks the user, device, and network against an application's policy before allowing access to the application.

Deploy or Update 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 your primary authentication source.

2. Add the attributes from the table below that correspond to the Duo attributes Mail attribute and Display 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,displayName in the "Attributes" field.

   Duo Attribute	Active Directory	OpenLDAP
   Mail attribute	mail	mail
   Display Name attribute	displayName	displayName

   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 the additional attributes not already present to the list, separated by a comma.

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 UserVoice when configuring SSO. Click the Download Certificate link to obtain the token signing certificate (the downloaded file is named "dag.crt").

   

Create the UserVoice Application in Duo

1. Log on to the Duo Admin Panel and navigate to Applications → Protect an Application.

2. Locate the entry for UserVoice with a protection type of "2FA with SSO self-hosted (Duo Access Gateway)" in the applications list. Click Protect to the far-right to start configuring UserVoice. See Protecting Applications for more information about protecting applications in Duo and additional application options.

3. The UserVoice subdomain is the subdomain used when logging into your organization's UserVoice account. For example, if your UserVoice login URL is yourcompany.uservoice.com then enter yourcompany as the subdomain name in Duo.

4. UserVoice uses the Mail attribute and Display Name attribute when authenticating. We've mapped the attributes to DAG supported authentication source attributes as follows:

   Duo Attribute	Active Directory	OpenLDAP	SAML IdP	Google	Azure
   Mail attribute	mail	mail	mail	email	mail
   Display Name attribute	displayName	displayName	displayName	name	displayName

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

5. Click Save Configuration to generate a downloadable configuration file.

   

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 UserVoice 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 UserVoice Application to Duo Access Gateway

Before you do this, verify that you updated the "Attributes" list for your Duo Access Gateway authentication source as specified here.

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 UserVoice SAML application JSON file you downloaded from the Duo Admin Panel earlier. Click the Upload button after selecting the JSON configuration file.

3. The UserVoice SAML application is added. Make note of the Login URL, you will need this later.

   

Enable UserVoice SSO

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

1. Log on to UserVoice as an administrative user with the "Account Owner" role and click on Admin Console under your username located in the upper right-hand corner of the screen.

2. Once on the "Admin Console" page click the gear icon in the lower left-hand corner of the screen to be taken to the Settings page.

3. On the "Settings" page click the Web portal tab and then click Edit... next to User authentication. A new window will appear.

4. On the "Edit User Authentication" screen click the button next to Single Sign-on (SSO).

5. Leave the SSO KEY field at its default.

6. Copy the Login URL information we made note of earlier in the Add the UserVoice Application to Duo Access Gateway section and paste it into the UserVoice SSO REMOTE SIGN-IN URL field.

   Example: https://yourserver.example.com/dag/saml2/idp/SSOService.phpspentity?id=yourcompany.uservoice.com

7. Copy the Logout URL information from the Duo Access Gateway admin console Metadata display and paste it into the UserVoice SSO REMOTE SIGN-OUT URL field.

   Example: https://yourserver.example.com/dag/saml2/idp/SingleLogoutService.php

8. Under the SAML SINGLE SIGN ON setting click Choose File and select the dag.crt file supplied by the Duo Access Gateway.

9. You can optionally choose to allow users to also sign in with their UserVoice password by clicking "include UserVoice Authentication".

10. After you've entered all the required information click Save.

Verify SSO

You can log on to UserVoice by navigating to your UserVoice SSO page e.g. yourcompany.uservoice.com and click Sign in in the top right-hand corner. This redirects to the Duo Access Gateway login page. Enter your primary directory logon information, approve Duo two-factor authentication, and get redirected back to the UserVoice site after authenticating.

Congratulations! Your UserVoice 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. Deployment Guides for AD FS versions 2.1, and 3.0/4.0 are available from Microsoft.

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 UserVoice. Learn more about configuring UserVoice SSO with AD FS at the UserVoice Developer Center.

After you have successfully configured and tested AD FS SSO login to UserVoice using your AD domain credentials, you can then install the Duo AD FS integration. AD FS protection is included with Duo Essentials, Duo Advantage, and Duo Premier 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 UserVoice.
