When an external dynamic list that requires SSL fails client or server authentication, you'll see the authentication failure in the EDL Distribution Status. Typically, if your environment is unable to connect or otherwise fetch the most current EDL from the server, your configuration retains the last successfully retrieved list and continues operating with the most recent EDL information until the connection is restored with the web server hosting the EDL. However, in cases where authentication to the EDL fails, the Security policy stops enforcing the EDL. Use the following process to view authentication failures related to external dynamic lists.
