Duo Single Sign-On for SyncplicityLast Updated: August 9th, 2023
Add two-factor authentication and flexible security policies to Syncplicity SAML 2.0 logins with Duo Single-Sign On. Our cloud-hosted SSO identity provider offers inline user enrollment, self-service device management, and support for a variety of authentication methods — such as passkeys and security keys, Duo Push, or Verified Duo Push — in the 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.
About Duo Single Sign-On
Duo Single Sign-On is our cloud-hosted SSO product which layers Duo's strong authentication and flexible policy engine on top of Syncplicity logins. Duo Single Sign-On acts as an identity provider (IdP), authenticating your users using existing on-premises Active Directory (AD) or another SSO IdP. Duo SSO prompts users for two-factor authentication and performs endpoint assessment and verification before permitting access to Syncplicity.
Duo Single Sign-On is available in 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 Syncplicity. Duo checks the user, device, and network against an application's policy before allowing access to the application.
Configure Single Sign-On
Before configuring Syncplicity with Duo SSO using Security Assertion Markup Language (SAML) 2.0 authentication you'll first need to enable Duo Single Sign-On for your Duo account and configure a working authentication source.
Once you have your SSO authentication source working, continue to the next step of creating the Syncplicity application in Duo.
Create the Syncplicity Application in Duo
Log on to the Duo Admin Panel and navigate to Applications.
Click Protect an Application and locate the entry for Syncplicity with a protection type of "2FA with SSO hosted by Duo (Single Sign-On)" in the applications list. Click Protect to the far-right to start configuring Syncplicity. See Protecting Applications for more information about protecting applications in Duo and additional application options. You'll need the information on the Syncplicity page under Downloads later.
Syncplicity uses the Mail attribute and Username attribute when authenticating. We've mapped the bridge attributes to Duo Single Sign-On supported authentication source attributes as follows:
Bridge Attribute Active Directory SAML IdP <Email Address> <Username> sAMAccountName Username
If you are using non-standard attributes for your authentication source, check the Custom attributes box and enter the name of the attributes you wish to use instead.
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.
Keep the Duo Admin Panel tab open. You will come back to it later.
Duo Universal Prompt
The new Universal Prompt provides a simplified and accessible Duo login experience for web-based applications, offering a redesigned visual interface with security and usability enhancements.
We've already updated the Duo Syncplicity application hosted in Duo's service to support the Universal Prompt, so there's no action required on your part to update the application itself. You can activate the Universal Prompt experience for users of new and existing Duo Syncplicity applications from the Duo Admin Panel.
Before you activate the Universal Prompt for your application, it's a good idea to read the Universal Prompt Update Guide for more information about the update process and the new login experience for users.
Activate Universal Prompt
Activation of the Universal Prompt is a per-application change. Activating it for one application does not change the login experience for your other Duo applications.
The "Universal Prompt" area of the application details page shows that this application is "Ready to activate", with these activation control options:
- Show traditional prompt: (Default) Your users experience Duo's traditional prompt via redirect when logging in to this application.
- Show new Universal Prompt: Your users experience the Universal Prompt via redirect when logging in to this application.
Enable the Universal Prompt experience by selecting Show new Universal Prompt, and then scrolling to the bottom of the page to click Save.
Once you activate the Universal Prompt, the application's Universal Prompt status shows "Activation complete" here and on the Universal Prompt Update Progress report.
Should you ever want to roll back to the traditional prompt, you can return to this setting and change it back to Show traditional prompt. However, this will still deliver the Duo prompt via redirect, not in an iframe.
Universal Update Progress
Click the See Update Progress link to view the Universal Prompt Update Progress report. This report shows the update availability and migration progress for all your Duo applications. You can also activate the new prompt experience for multiple supported applications from the report page instead of visiting the individual details pages for each application.
Enable Syncplicity for SSO
Log into your Syncplicity account as an administrative user.
Click the Settings tab, and then click Custom domain and single sign-on under "Account Configuration".
Type your desired domain name into the Custom Domain field.
Click the Enabled radio button under "Single Sign-On Status".
Return to the Duo Admin Panel. Copy the Entity Id and paste it into the Syncplicity Entity Id field.
Return to the Duo Admin Panel. Copy the Sign-in page URL and paste it into the Syncplicity Sign-in page URL field.
Return to the Duo Admin Panel. Type your Syncplicity custom domain into the Custom Domain field under "Service Provider".
In the Duo Admin Panel, click Download certificate under "Downloads".
Scroll to the bottom of the page and click Save.
Return to your Syncplicity account page. Click Choose File and open the certificate file you downloaded earlier.
In your Syncplicity account page, click the Enable Silent Onboarding... checkbox.
Click Save changes.
Learn more about Syncplicity SSO at Syncplicity Support.
You can log on to Syncplicity by navigating to your Syncplicity SSO page e.g., https://my.syncplicity.com/. Enter your email address and click Next to be redirected to Duo Single Sign-On to begin authentication.
Active Directory Login
With Active Directory as the Duo SSO authentication source, enter the primary username (email address) on the Duo SSO login page and click or tap Next.
Enter the AD primary password and click or tap Log in to continue.
With another SAML identity provider as the Duo SSO authentication source, Duo SSO immediately redirects the login attempt to that SAML IdP for primary authentication. Users do not see the Duo SSO primary login screen.
Successful verification of your primary credentials by Active Directory or a SAML IdP redirects back to Duo. Complete Duo two-factor authentication when prompted and then you'll return to Syncplicity to complete the login process.
* Universal Prompt experience shown.
Syncplicity supports SP-initiated authentication only, meaning that you must start your SSO login from that application's sign-in page. You won't be able to add Syncplicity as an application tile in Duo Central for IdP-initiated logins.
Congratulations! Your Syncplicity users now authenticate using Duo Single Sign-On.
Enable Remembered Devices
To minimize additional Duo two-factor prompts when switching between Syncplicity and your other Duo Single Sign-On SAML applications, be sure to apply a shared "Remembered Devices" policy to your SAML applications.
