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 (DAG), our on-premises SSO product, layers Duo's strong authentication and flexible policy engine on top of GoToMeeting 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 GoToMeeting.
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 GoToMeeting. Duo checks the user, device, and network against an application's policy before allowing access to the application.
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.
Add the attributes from the table below that correspond to the Duo attributes Mail attribute and Username 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,sAMAccountName in the "Attributes" field.
|Duo Attribute||Active Directory||OpenLDAP|
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.
After completing the initial DAG configuration steps, click Applications on the left side of the Duo Access Gateway admin console.
Scroll down the Applications page to the Metadata section. This is the information you need to provide to GoToMeeting when configuring SSO. Click the Download Certificate link to obtain the token signing certificate (the downloaded file is named "dag.crt").
Add the Duo Access Gateway as a new single sign-on provider for GoToMeeting.
Log on to the GoToMeeting as an administrative user and navigate to GoToMeeting SSO Page.
Select the Configure manually button.
Copy the Logout URL information from the Duo Access Gateway admin console Metadata display and paste it into the GoToMeeting Sign-out page URL field.
Copy the SSO URL information from the Duo Access Gateway admin console Metadata display and paste it into the GoToMeeting Sign-in page URL field.
The "Verification certificate" is the DAG Metadata certificate supplied by Duo Access Gateway. Click the link to select the dag.crt file you downloaded from the DAG admin console "Application" page earlier.
After you've entered all the required information click Save.

Log on to the Duo Admin Panel and navigate to Applications.
Click Protect an Application, locate SAML - GoToMeeting in the applications list, and click Protect this Application. See Getting Started for help.
GoToMeeting uses the Mail attribute when authenticating. We've mapped Mail attribute to DAG supported authentication source attributes as follows:
|Duo Attribute||Active Directory||OpenLDAP||SAML IdP||Azure|
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.
Click Save Configuration to generate a downloadable configuration file.
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.
Click the Download your configuration file link to obtain the GoToMeeting 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!
Return to the Applications page of the DAG admin console session.
Click the Choose File button in the "Add Application" section of the page and locate the GoToMeeting SAML application JSON file you downloaded from the Duo Admin Panel earlier. Click the Upload button after selecting the JSON configuration file.
The GoToMeeting SAML application is added.
You can log on to GoToMeeting by navigating to the GoToMeeting Sign In page and then clicking Use my company ID. You will be directed to type in your e-mail address and click Sign In. 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 GoToMeeting site after authenticating.
If using the GoToMeeting mobile app, tap the “Use my company ID” link at the bottom of the login screen, enter your federated e-mail address, and then authenticate to Duo Access Gateway.
Congratulations! Your GoToMeeting users now authenticate using Duo Access Gateway.
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 GoToMeeting. Learn more about configuring GoToMeeting SSO with AD FS at the GoToMeeting Global Support site.
After you have successfully configured and tested AD FS SSO login to GoToMeeting 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 GoToMeeting.
