Horizon attempts to show associated share servers when displaying share network details in the project share-networks dashboard. But unless the horizon user is an admin this generates a 403 exception which in turn causes Horizon to pop-up an error message about being unable to retrieve share network details. So instead catch exceptions collecting share server information in this context and continue on gracefully, presenting the share server details that are available.
