We're migrating from Zen4 to ZCM. In Zen4, we placed most of the files for
an application on a mapped network drive. If an app was associated with a
workstation,, we would use a UNC path (ex.
\zen_serverzen_volumeapp_folder). In order to have the ws access the
install dir, we made all the workstation trutess of the app_folder.

In ZCM, ws object are moved away from eDir so we cannot have to ws to be a
trustee of the app_folder. How can we solve that?
