Symptoms

When searching for a SP User or Group in K2 Workspace (for example when adding a Role Item or trying to find SP users/groups when applying Process Permissions), it returns no results. Doing a blank search however returns all results.

I cannot add permissions for SP groups to start/view users. When I search for users/groups in the add permissions screen, no entries are returned.
 

Diagnoses

This only happens with a SharePoint 2013 native site collection.
 

Resolution

A coldfix was sent to resolve this issue, two DLL files have been replaced in Bin and HostServerBin that will allow interaction with SharePoint 2013 sites.

This fix will be included in 4.6.9
