> The UI and supervisors authenticate to nimbus through kerberos.  But they initiate a new connection each time they do so, and even use a new Subject for each connection.  This means that the client must fetch a new service ticket each time and adds a lot of load on the KDC.
> In order to reuse the subject between sessions we propose cacheing the Login instead of creating a new one each time.
