GetUser client method returns null reference
description
I recently installed the C# version of IWeb on my DNN 6.0 site and tried using the client connector. I tried to get a user based on the GUID userID (source from the SQL Server Managment Studio). The client is unable to get the user with an null reference error. After looking at the web method, it looks like the ID is an 'int' but in SQL Server it appears to be 'uniqueidentifier' or a GUID.
