Duo Protection for Jamf Pro with Duo Access GatewayLast Updated: June 15th, 2023
Duo Access Gateway reaches Last Day of Support on October 26, 2023 for Duo Essentials, Advantage, and Premier customers. After that date, Duo Support may only assist with the migration of existing Duo Access Gateway applications to Duo Single Sign-On. Customers may not create new DAG applications after May 19, 2022. Please see the Guide to Duo Access Gateway end of life for more details.
Use the Duo Single Sign-on for Jamf Pro Server application to protect Jamf Pro Server with Duo Single Sign-On, our cloud-hosted identity provider featuring Duo Central and the Duo Universal Prompt.
Duo Protection for Jamf Pro is compatible with Jamf Cloud and Jamf Pro 9.93 or greater.
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.
Duo Access Gateway
Duo Access Gateway (DAG), our on-premises SSO product, layers Duo's strong authentication and flexible policy engine on top of Jamf Pro 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 Jamf Pro.
Duo Access Gateway is included in the 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 Jamf Pro. Duo checks the user, device, and network against an application's policy before allowing access to the application.
Deploy or Update Duo Access Gateway
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 Mail attribute
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. You'll need to provide the Entity ID URL to Jamf Pro when configuring SSO.
Create the Jamf Pro Application in Duo
Log on to the Duo Admin Panel and navigate to Applications.
Click Protect an Application and locate the entry for Jamf Pro 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 Jamf Pro. See Protecting Applications for more information about protecting applications in Duo and additional application options.
The Domain name is the domain URL of your Jamf server. Example: If your Jamf Pro sign on URL is https://jamf.yourserver.com:8443 you would enter jamf.yourserver.com:8443.
Jamf Pro 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 Mail attribute
If your organization uses other directory attributes than the one listed here then enter that attribute name instead. If you've already configured the attributes list for another cloud service provider, append this additional attribute to the list.
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 Jamf Pro 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!
Add the Jamf Pro Application to Duo Access Gateway
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 Jamf Pro SAML application JSON file you downloaded from the Duo Admin Panel earlier. Click the Upload button after selecting the JSON configuration file.
The Jamf Pro SAML application is added.
Enable Jamf Pro SSO
Add the Duo Access Gateway as a new single sign-on provider for Jamf Pro.
Log on to Jamf Pro as an administrative user and click the gear icon in the upper right-hand corner.
Under "System Settings" click Single Sign-On.
On the "Single Sign-On" page, scroll down to the bottom and click Edit. The page will reload.
Under "Single Sign-On (SSO) Utilization select Jamf Pro Server. You can select additional services at this time to protect with SSO. Note that if you enable the "Allow bypass for all users" option then your JSS users may continue to login without Duo authentication.
Under "User Mapping: SAML" select NameID.
Under "User Mapping: JAMF Pro" select Email.
Leave "Group Attribute Name" and "RDN Key for LDAP Group" at their default values.
Select Other from the "Identity Provider" drop-down. New options will appear. Type Duo Access Gateway into the Other Provider text field.
Select Metadata URL from the "Identity Provider Metadata Source" drop-down. A new form appears under the drop-down. Paste in the Duo Access Gateway Entity ID URL from the DAG Metadata information.
Leave the "Entity ID" field at its default value.
Click the drop-down under "Jamf Pro Signing Certificate" and select Generate Certificate. New options will appear. Click Generate Certificate to create a certificate.
Set Token Expiration to the maximum time (in minutes) users stay logged into Jamf before they have to authenticate again.
Learn more about Jamf Pro SSO at the Casper Suite Administration Guide.
Log in with SSO
If your organization enabled the Duo Access Gateway portal, log into the portal page using the link provided by your administrator. Click Jamf Pro from the dashboard to access the application.
You can also access Jamf Pro by using your Jamf Pro login URL. This redirects to the Duo Access Gateway login page. Enter your primary directory logon information, approve Duo two-factor authentication, and get redirected back to the Jamf Pro site after authenticating.
Congratulations! Your Jamf Pro users now authenticate using Duo Access Gateway.
If you plan to permit use of WebAuthn authentication methods (security keys, U2F tokens, or Touch ID) in the traditional Duo Prompt, Duo recommends configuring allowed hostnames for this application and any others that show the inline Duo Prompt before onboarding your end-users.
The Duo Universal Prompt has built-in protection from unauthorized domains so this setting does not apply.
Microsoft AD FS
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 Jamf Pro. Learn more about configuring Jamf Pro SSO with AD FS at the Casper Suite Administration Guide.
After you have successfully configured and tested AD FS SSO login to Jamf Pro 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 Jamf Pro.
