    Description

      Currently the IPC client sends the UGI which contains the user/group information for the Server. However this represents the groups for the user on the client-end. The more pertinent mapping from user to groups is actually the one seen by the Server. Hence the client should only send the user and we should add a 'group mapping service' so that the Server can query it for the mapping.
