How to enable Zenoss to receive snmp v3 traps

Hi,
We have a setup where a whole bunch of servers send snmp v1 traps to zenoss. We have scripts running on these servers which send traps to zenoss depending on whether or not certain actions in these scripts execute successfully. Anyway, we are now required to send v3 traps rather than version 1, but I can't find any documentation on how to configure zenoss to receive snmp v3 traps.

Can anyone help

Thanks

Denis
