If there is a time mismatch beyond a five-minute boundary between clients, intermediaries and servers, erroneous ticket invalidation will occur when KCD is in use. To avoid this problem, connect the LoadMaster to an NTP host server. The same host used by clients and servers in the infrastructure should be used by LoadMaster. An external NTP host server can be used if the LoadMaster can access it. However, if the LoadMaster is internal only – you will need to set up your own NTP server.

To configure the NTP settings on the LoadMaster, follow the steps below:

  1. In the main menu, select System Configuration > System Administration > Date/Time.

  2. Enter the IP address of the NTP host(s) and click Set NTP host.
  3. Select a time zone in the Set time zone (UTC) drop-down menu. Click Set time zone.
Note: The time zone needs to be manually set even when an NTP server is used.
