Duo Protection for Bomgar Remote Support and Privileged Access with Duo Access Gateway

Last Updated: April 20th, 2023

Duo offers a variety of methods for adding two-factor authentication and flexible security policies to Bomgar Remote Support and Privileged Access SSO logins, complete with inline self-service enrollment and Duo Prompt.

Duo Access Gateway reaches Last Day of Support on October 26, 2023 for Duo Essentials, Advantage, and Premier customers. As of that date Duo Support may only assist with the migration of existing Duo Access Gateway applications to Duo Single Sign-On. Customers may not create new DAG applications after May 19, 2022. Please see the Guide to Duo Access Gateway end of life for more details.

Use the Duo Single Sign-on for BeyondTrust application to protect BeyondTrust with Duo Single Sign-On, our cloud-hosted identity provider featuring Duo Central and the Duo Universal Prompt.


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.

This application requires Bomgar Cloud for Remote Support or Bomgar 16.1.1 and higher.

If you’re looking to protect non-SAML logins to your Bomgar Remote Support or Privileged Access services, please see our instructions for RADIUS 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 Bomgar 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 Bomgar.

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 Bomgar. 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 an Authentication Source.

  2. Add the attributes from the table below that correspond to the Duo attributes Mail attribute, First Name attribute, and Last 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,givenName,sn 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 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 Bomgar when configuring SSO. Click the Download XML metadata link to obtain the DAG metadata file (the downloaded file is named "dag.xml").

    DAG Metadata Information

Create the Bomgar Application in Duo

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

  2. Click Protect an Application and locate the entry for Bomgar 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 Bomgar. See Protecting Applications for more information about protecting applications in Duo and additional application options.

  3. The Domain name is the domain URL used when logging into your company's Bomgar. For example, if your Bomgar login URL is then enter as the domain name in Duo.

  4. Bomgar uses the Mail attribute, First Name attribute, and Last Name attribute when authenticating. We've mapped Mail attribute, First Name attribute, and Last Name attribute 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 givenName gn givenName given_name givenName
    Last Name sn sn sn family_name surname

    If you are using a non-standard attributes for your authentication source, check the Custom attributes box and enter the name of the attributes 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 Bomgar 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!

Learn more about Bomgar SSO at the Bomgar Support site.

Log in with SSO

Navigate to your Bomgar login page eg. and click the Use SAML Authentication link. 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 Bomgar site after authenticating.

DAG Login and Authentication Prompt

To log in using the Bomgar Console select SAML Credentials from the "Authenticate Using" drop-down. Click Login and a browser will open that redirects to the Duo Access Gateway login page. Enter your primary directory logon information, approve Duo two-factor authentication. After you've successfully authenticated a special Bomgar file will be downloaded. Click on the Bomgar file and it will log you into the Bomgar Console.

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

Configure Allowed Hostnames

If you plan to permit use of WebAuthn authentication methods (security keys, U2F tokens, or Touch ID) in the traditional Duo Prompt, Duo recommends configuring allowed hostnames for this application and any others that show the inline Duo Prompt before onboarding your end-users.

The Duo Universal Prompt has built-in protection from unauthorized domains so this setting does not apply.

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 Bomgar. Learn more about configuring Bomgar SSO with AD FS at the Bomgar Support site.

After you have successfully configured and tested AD FS SSO login to Bomgar 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 Bomgar.
