Duo Single Sign-On for Adobe Admin Console

Overview

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 Adobe Admin Console logins using Security Assertion Markup Language (SAML) 2.0. Duo Single Sign-On acts as an identity provider (IdP), authenticating Duo-hosted users or users in external authentication sources, like an existing on-premises Active Directory (AD) or any SAML 2.0 IdP. Duo's strong multi-factor authentication further verifies users before permitting access to Adobe Admin Console.

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 Adobe Admin Console users complete two-factor authentication at every login, but only once every seven days when accessing a different application. Duo checks the user, device, and network against an application's policy before allowing access to the application.

Configure Single Sign-On

Before configuring Adobe Admin Console with Duo SSO using SAML 2.0 authentication, you'll first need to complete Duo SSO configuration, which may include setting up a working external authentication source if your organization will not store your user identities in Duo.

Once you complete initial Duo SSO configuration, continue to the next step of creating the Adobe Admin Console application in Duo.

Create the Adobe Admin Console Application in Duo

1. Log in to the Duo Admin Panel and navigate to Applications → Application Catalog.

2. Locate the entry for Adobe Admin Console with the "SSO" label in the catalog. Click the + Add button to start configuring Adobe Admin Console. See Protecting Applications for more information about protecting applications with Duo and additional application options. You'll need the information on the Adobe Admin Console page under Downloads later.

3. No users can log in to new applications until you grant access. Update the User access setting to grant access to this application to users in selected Duo groups, or to all users. Learn more about user access to applications. If you do not change this setting now, be sure to update it so that your test user has access before you test your setup.

4. Adobe Admin Console uses the Mail attribute, First name attribute, Last name attribute, and Country attribute when authenticating. We've mapped the attributes to Duo Single Sign-On supported authentication source attributes as follows:

   Attribute	Active Directory	SAML IdP
   <Email Address>	mail	Email
   <First Name>	givenName	FirstName
   <Last Name>	sn	LastName
   <Country>	country	CountryCode

   If you are using non-standard attributes for your authentication source, check the Custom attributes box and enter the names of the attributes you wish to use instead.

5. 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.

6. Keep the Duo Admin Panel tab open. You will come back to it later.

Duo Universal Prompt

The Duo Universal Prompt provides a simplified and accessible Duo login experience for web-based applications, offering a redesigned visual interface with security and usability enhancements.

Universal Prompt	Traditional Prompt

The Duo Adobe Admin Console application supports the Universal Prompt by default, so there's no additional action required on your part to start using the newest authentication experience.

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. Universal Prompt is already activated for new Adobe Admin Console applications at creation.

The "Universal Prompt" area of the application details page shows that this application's status is "Activation complete", with these activation control options:

• Show traditional prompt: Your users experience Duo's traditional prompt via redirect when logging in to this application.
• Show new Universal Prompt: (Default) Your users experience the Universal Prompt via redirect when logging in to this application.

The application's Universal Prompt status shows "Activation complete" both here and on the Universal Prompt Update Progress report.

For the time being, you may change this setting to Show traditional prompt to use the legacy experience. Keep in mind that support for the traditional Duo prompt ended for the majority of applications in March 2024. This option will be removed in the future.

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 Adobe Admin Console for SSO

1. Log into your Adobe Admin Console account as an administrator.

2. At the top of the page, click Settings.

23. Follow the instructions in the pop-up window to configure your host domain with the DNS record and then click Validate. You will return to your directory page.

24. On your domain row, the "Status" column must display Active before going to the next step.

25. After your domain status is active, click the Authentication tab on your directory page.

26. In the "SAML Provider" tile, click Test. You are automatically redirected to Duo Single Sign-On to test your configuration.

Using SSO

You can log on to Adobe Admin Console by navigating to your Adobe Admin Console SSO page e.g., https://adminconsole.adobe.com. Enter your email address and click Continue to be redirected to Duo Single Sign-On to begin authentication.

Duo-hosted or Active Directory Login

With Duo or 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 Duo or AD primary password and click or tap Log in to continue.

When using Duo Passwordless you won't need to enter a password, and will proceed directly to Duo authentication.

SAML Login

The SAML login experience depends on your Duo SSO routing rules configuration.

With another SAML identity provider as the only enabled Duo SSO authentication source and the default routing rule in place, Duo SSO immediately redirects the login attempt to that SAML IdP for primary authentication. Users do not see the Duo SSO primary login screen.

If you have multiple enabled SAML authentication sources or custom routing rules in place, then users enter their primary username (email address) on the Duo SSO login page and then will be redirected to the correct external SAML identity provider.

Duo Authentication

Successful verification of your primary credentials by Duo, Active Directory, or a SAML IdP redirects back to Duo. Complete Duo two-factor authentication when prompted and then you'll return to Adobe Admin Console to complete the login process.

* Universal Prompt experience shown.

Adobe Admin Console 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 Adobe Admin Console as an application tile in Duo Central for IdP-initiated logins.

Congratulations! Your Adobe Admin Console users now authenticate using Duo Single Sign-On.

See the full user login experience, including expired password reset (available for Active Directory authentication sources) in the Duo End User Guide for SSO.

Grant Access to Users

If you did not already grant user access to the Duo users you want to use this application be sure to do that before inviting or requiring them to log in with Duo.

Enable Remembered Devices

To minimize additional Duo two-factor prompts when switching between Adobe Admin Console and your other Duo Single Sign-On SAML applications, be sure to apply a shared "Remembered Devices" policy to your SAML applications.
