Symptoms

After installing the coldfix for K2 4.6.10, we get an error when trying to access Worklist on Workspace.
 

Diagnoses

It seems there is a rights and permissions issue Identity.Identity Table needs to be refreshed.
 

Resolution 

Set the 'Resolve Nested Groups' option in workspace and restarted the K2 service.

Also running the sql script:
UPDATE /K2HostServer].tIdentity].dIdentity]
SET bExpireOn] = GETDATE()
,(Resolved] = 0
, ContainersResolved] = 0
, ContainersExpireOn] = GETDATE()
,(MembersResolved] = 0
, MembersExpireOn] = GETDATE()
