When a new certificate is imported by following steps from KB 160518 in a tomcat keystore (using a new alias name) enforce console loads with old certificate.
Release : NA
Java finds the first matching CN key in the keystore and loads the certificate, even though there is a newer certificate with matching CN value.
Backup the keystore and delete the alias with older certificate using below command.
keytool -delete -alias <alias_name> -keystore <ketstore_path> -storepass <keystore_password>
Restart SymantecDLPManagerService and check if new certificate is loaded.
