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 Robin 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 Robin.
Duo Access Gateway is included in the Duo Beyond, Duo Access, and Duo MFA 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 Robin. 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, 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|
|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.
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 Robin 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 Robin.
Log on your Robin site as an administrator. Click on the Settings link in the navigation bar.
On the Details tab under Details verify that you have the Name field populated and that you have a custom URL. Make note of that URL, you will need it later.
Click on the Integrations tab. Scroll to the bottom and click Add next to SAML 2.0. A new window will appear.
On the Configure SAML Single Sign On page click the Provider drop down and select Custom.
Copy the SSO URL information from the Duo Access Gateway admin console Metadata display and paste it into the Robin SAML SSO URL field.
Copy the Entity ID information from the Duo Access Gateway admin console Metadata display and paste it into Robin's Identity Provider Issuer field.
The "Public Certificate" is the text of the DAG Metadata certificate supplied by Duo Access Gateway. Open the dag.crt file in a text editor (like Notepad), and copy the entire contents of the file (including the
-----BEGIN CERTIFICATE----- and
-----END CERTIFICATE----- lines). Paste the certificate file text into this field.
After you've entered all the required information click Configure.
Learn more about Robin SSO at the Robin Help Center.
Log on to the Duo Admin Panel and navigate to Applications.
Click Protect an Application, locate SAML - Robin in the applications list, and click Protect this Application. See Getting Started for help.
Robin 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||Azure|
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.
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 Robin 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 Robin SAML application JSON file you downloaded from the Duo Admin Panel earlier. Click the Upload button after selecting the JSON configuration file.
The Robin SAML application is added.
You can log on to Robin by going to https://dashboard.robinpowered.com/login and click Single Sign On. You will be asked to enter in your company name located at the end of your custom URL eg. your-company you made note of earlier and click Sign in. You will be redirected to the Duo Access Gateway login page. Enter your primary directory logon information, approve Duo two-factor authentication, and get redirected back to the Robin site after authenticating.
Congratulations! Your Robin 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. 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 Robin. Learn more about configuring Robin SSO with AD FS at the Robin Help Center.
After you have successfully configured and tested AD FS SSO login to Robin 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 Robin.
