Enhancements to Duo Single Sign-On configuration options

  • Added support for configuring more than one Assertion Consumer Service (ACS) URL on the Generic SSO application configuration page to more easily allow SAML service providers with multiple ACS URLs to be configured with Duo Single Sign-On protection.
  • Added an optional Logout Redirect URL field to the SAML identity provider configuration page. Configuring this field allows Duo administrators to send end-users to a specified URL when they log out of Duo Single Sign-On.

New status for Universal Prompt Update Progress report

  • Applications that have been updated to support the future release of the Duo Universal Prompt will now show a status of “Waiting on Duo” in the Universal Prompt Update Progress report in the Duo Admin Panel, and on relevant application configuration pages in the Universal Prompt section. This label reflects that the new prompt has not yet been released, and the applications are ready to support it once it is released.
  • Applications in this state will be listed under the “New Prompt Ready” tab in the Update Progress report.
  • Customers participating in a private preview of the Universal Prompt UI will see a different label for their updated applications, “New Prompt Ready,” to indicate they can test the new prompt.
  • For more information about the Universal Prompt Project, review this documentation.
