New Duo Trusted Endpoints integration for Jamf is now generally available

  • Jamf with Device Health no longer relies on certificates to check for device trust and provides a more accurate and up-to-date picture of the trusted status of Jamf-managed macOS devices.
  • Instead of certificates, the new Jamf integration option uses read-only API access to your Jamf cloud or on-premises tenant, combined with deployment of the Duo Device Health application to Jamf-managed devices, to build a list of managed devices in your environment.

    • Fixed issue with certain Windows updates having a stuck “requires reboot” flag that would cause the home screen to be incorrectly marked as out of date.
    • Fixed an issue with device identifier formatting.
    • Added infrastructure to allow for long-running health checks.

New features, enhancements, and other improvements

Simpler authentication experience for mobile devices managed via Duo Trusted Endpoints

  • End-users will see a simpler mobile trust check and authentication flow when accessing a Duo-protected application from their iOS or Android device that uses Duo Trusted Endpoints to manage mobile device trust. The updated flow, called Duo Mobile Inline Auth, removes an extra step when interacting with Duo Mobile as part of the device health check.
  • To learn more and see which integrations will use Duo Mobile Inline Auth, refer to this Duo Knowledge Base article.

Trusted Endpoints Configuration page now displays sync status of MDMs

  • The Trusted Endpoints Configuration page in the Duo Admin Panel will now display the status of whether a Trusted Endpoints deployment has synced with an MDM, and will record any errors that resulted in a failed sync.

Duo Admin API endpoints for hardware tokens now return basic information about assigned administrators

  • Information returned on hardware tokens via the Admin API will now display the assigned administrator. This information was already available via the Admin Panel Hardware Tokens page.

Duo Admin API endpoints no longer return changed legacy parameters on POST

  • Legacy parameters can still be sent to the Admin API without error and will continue to have no effect, as stated in Duo’s documentation. However, these values are no longer stored and a response to POST may not reflect what was sent; responses will contain whatever was previously stored in the database. If you have scripts that rely on these legacy parameters, we recommend you update them. In a future update, GET and POST will both return hardcoded values for these legacy parameters.
  • Affected endpoints and parameters are:
    • Create Group (/admin/v1/groups) and Update Group (/admin/v1/groups/[group_id])
      • push_enabled
      • sms_enabled
      • voice_enabled
      • mobile_otp_enabled
    • Create Integration (/admin/v1/integrations) and Modify Integration (/admin/v1/integrations/[integration_key])
      • enroll_policy
      • ip_whitelist
      • ip_whitelist_enroll_policy
      • trusted_device_days
    • Modify Settings (/admin/v1/settings)
      • push_enabled
      • sms_enabled
      • voice_enabled
      • mobile_otp_enabled
      • u2f_enabled

Additional safeguard added when Managed Service Provider administrators delete sub-accounts

  • When Managed Service Provider administrators or other administrators with access to sub-accounts delete a sub-account, they will now need to type delete me when prompted to confirm deletion. This step has been added to guard against accidental deletion of sub-accounts.

Bug fixes

  • Fixed a bug that caused log entries for username aliases to be added to authentications for users who have no aliases. The invalid aliases appeared as a non-normalized form of the username, such as a different capitalization style. This bug affected the Authentication Log in both the Admin Panel and via the Admin API.
  • Fixed an issue where attempting to download a SAML encryption or signing certificate associated with Duo administrator SAML single sign-on would sometimes result in being redirected to the Admin Panel login page when switching between a parent account and a sub-account such as those used by Managed Service Providers.
