Looking for a cloud-hosted SSO solution? Learn more about Duo Single Sign-On.
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 Clarizen 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 Clarizen.
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 Clarizen. Duo checks the user, device, and network against an application's policy before allowing access to the application.
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 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 Clarizen 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 Clarizen.
Log on to Clarizen as an administrative user and click on your username in the upper right-hand side. Select Settings from the dropdown.
On the "Global Settings" page click Edit next to Federated Authentication . A pop-up screen will appear.
Click the button next to Enabled Federated Authentication so that it displays a checkmark with a green background.
The "Certificate" is 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.
Copy the SSO URL information from the Duo Access Gateway admin console Metadata display and paste it into the Clarizen Sign-in URL field.
Copy the Logout URL information from the Duo Access Gateway admin console Metadata display and paste it into the Clarizen Sign-out URL field.
Change Enable Password authentication to No One to enforce SSO.
Click Show Advanced Options to reveal more options on the page.
Change Name ID Format to SAML:1.1 Email.
Leave all other options at their defaults.
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 and locate the entry for Clarizen 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 Clarizen. See Protecting Applications for more information about protecting applications in Duo and additional application options.
Clarizen 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 Clarizen 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!
Before you do this, verify that you updated the "Attributes" list for your Duo Access Gateway authentication source as specified here.
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 Clarizen SAML application JSON file you downloaded from the Duo Admin Panel earlier. Click the Upload button after selecting the JSON configuration file.
The Clarizen SAML application is added.
You can log on to Clarizen using IdP-initiated SSO via Duo Access Gateway using the Login URL provided by the DAG server when you created the Clarizen application in the DAG admin console (https://yourserver.example.com/dag/saml2/idp/SSOService.php?spentityid=Clarizen).
Enter your primary directory logon information and approve Duo two-factor authentication.
After authenticating you'll be forwarded to the Clarizen site.
Congratulations! Your Clarizen users now authenticate using Duo Access Gateway.
If you plan to permit use of WebAuthn authentication methods (security keys, U2F tokens, or Touch ID), Duo recommends enabling hostname whitelisting for this application and any others that show the inline Duo Prompt before onboarding your end-users.
Clarizen does not support SP-initiated SSO login at this time.
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 Clarizen. Learn more about configuring Clarizen SSO with AD FS at the Clarizen Success Site.
After you have successfully configured and tested AD FS SSO login to Clarizen 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 Clarizen.
