Resolution
K2 can be configured to use Kerberos if you wish, but it is not required.
K2 can use K2 Pass-Through Authentication out-of-the-box when K2 and Sharepoint are on different machines:

This is configured when running the K2 Blackpearl Setup Manager:

To configure K2 to use Kerberos, please see the documentation below:

When K2 is configured for Kerberos, you will likely also need the 'K2 Windows Token Service' to be configured as follow:
