Troubleshooting Steps

To resolve this issue: 

  1. Go to Workspace > Management Console > User Managers > K2 > Settings.
  2. Check the Ignore Foreign Principals setting:


  3. Restart the K2 blackpearl service.
  4. Re-enable the user:

    UPDATE [K2].[Identity]
    SET Enabled = 1
    WHERE FQN = 'K2:[Domain]\[Username]'

  5. Refresh the identity:

    UPDATE [K2].[Identity].[Identity]
    SET [ExpireOn] = GETDATE() ,
    [Resolved] = 0 ,
    [ContainersResolved] = 0 ,
    [ContainersExpireOn] = GETDATE() ,
    [MembersResolved] = 0 ,
    [MembersExpireOn] = GETDATE()
    WHERE FQN = 'K2:[Domain]\[Username]'

  6. Run the UMUser SmartObject from the SmartObject Tester: SmartObject Explorer > All SmartObjects > UMUser Gets User Details:


  7. Verify whether the user is able to complete tasks via SmartActions.
