1. Download the Duo Security Integration Kit .zip archive from the Add-ons tab of the PingFederate downloads page.
  2. Stop PingFederate.
  3. If you are upgrading an existing deployment, delete earlier versions of the integration files.
    • For upgrades from Duo Security Integration Kit 3.0 or later: delete pf-duo-security-integration-kit-<version>.jar from <pf_install>/pingfederate/server/default/deploy.
    • For upgrades from Duo Security Integration Kit 2.2 or earlier:
      1. Delete the duo.adapter.template.html file from <pf_install>/pingfederate/server/default/conf/template.
      2. Delete the following files from <pf_install>/pingfederate/server/default/deploy:
        • pf-duo-security-adapter-<version>.jar
        • duo-web/js/Duo-Web-v2.min.js
  4. Extract the .zip archive and merge the contents of the dist directory with your <pf_install>/pingfederate directory.
  5. If there is more than one version of the pf-authn-api-sdk-<version>.jar file in your <pf_install>/pingfederate/server/default/lib directory, delete all but the latest version of the file.
  6. Start PingFederate.
  7. If you operate PingFederate in a cluster, repeat steps 2-6 for each engine node.
