Symptoms
Active Directory Service2 issue with GetUsers when passing in manager
Diagnoses
When trying to return a list of the users managed by the current user however you cannot get the expected result set when passing in the manager input parameter. You have tried using both ad username, Display Name and Domain however none appear to work.
You also cannot get the GetUserPeers to work when passing in an AD Username as the parameter.
Resolution
This issue has been identified as a bug and will be addressed within future version of K2. For the time being it will be best to use the UM user smart object which has similar functionality as the AD user smart object as it allows you to execute get user methods to bring back users from Active directory and sharepoint also.
