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 Bonusly 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 Bonusly.
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 Bonusly. 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 an Authentication Source.
Add the attribute from the table below that corresponds to the Duo Mail attribute in the "Attributes" field when configuring your Active Directory or OpenLDAP authentication source in the DAG admin console. For example, if Active Directory is your authentication source, enter mail in the "Attributes" field.
|Duo Attribute||Active Directory||OpenLDAP|
If your organization uses another directory attribute than the ones listed here then enter that attribute name instead. If you've already configured the attributes list for another cloud service provider, append the additional attribute 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 Bonusly when configuring SSO.
Add the Duo Access Gateway as a new single sign-on provider for Bonusly.
Log on to Bonusly as an administrative user and navigate to Settings → Integration → Single Sign-On. Click on SAML.
Make note of the SSO URL on the Bonusly SAML Integration page. You will need this information later.
Copy the SSO URL information from the Duo Access Gateway admin console Metadata display and paste it into the Bonusly IdP SSO target URL field.
Leave the IdP Login URL field blank.
Copy the Entity ID URL from the Duo Access Gateway admin console metadata display and paste it into the Bonusly SSO IdP Issuer field.
Leave the X.509 Cert field blank.
Copy the Fingerprint from the Duo Access Gateway admin console Metadata display and paste it into the Bonusly Cert fingerprint field.
You can force SSO login by checking the box next to Disable web login.
You can turn off manual user provisioning by checking the box next to Disable user mgmt.
After you've entered all the required information click Save.
Learn more about Bonusly SSO by contacting Bonusly Support.
Log on to the Duo Admin Panel and navigate to Applications.
Click Protect an Application, locate SAML - Bonusly in the applications list, and click Protect this Application. See Getting Started for help.
Copy the Bonusly SSO URL from Enable Bonusly SSO and paste it into the SSO URL field in the Duo Admin Panel.
Bonusly 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 when done.
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 Bonusly 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 Bonusly SAML application JSON file you downloaded from the Duo Admin Panel earlier. Click the Upload button after selecting the JSON configuration file.
The Bonusly SAML application is added.
You can log on to Bonusly via Duo Access Gateway using the Login URL provided by the DAG server when you created the Bonusly application in the DAG admin console (https://yourserver.example.com/dag/saml2/idp/SSOService.php?spentityid=https://bonus.ly).
This takes you to the Duo Access Gateway login page. Enter your primary directory logon information, approve Duo two-factor authentication, and get redirected to the Bonusly site.
Congratulations! Your Bonusly 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 Bonusly. Learn more about configuring Bonusly SSO with AD FS at the Bonusly Support Contact Site.
After you have successfully configured and tested AD FS SSO login to Bonusly 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 Bonusly.
