ROOT CAUSE
Authentication or Usepreauthenticationcookie was set to false. By default, Pega Platform generated a cookie for each user to track the user's requestor ID throughout the User session. The setting added security to the cookie and helped guard against replay attacks.
If this entry was set to false, the cookie contained the same value if the user was authenticated or not.
If this entry was set to true, Pega Platform used a different cookie value when the requestor is not authenticated.
Resolution
Perform the following local-change:
Set the Authentication or Usepreauthenticationcookie Dynamic System Setting (DSS) to true.
