This module allows access to the website shared dropbox accout by any authenticated user, and there appears to be no way to alter this. Since anyone can create an account on our Drupal installation, this is too open for us. We would like the Dropbox documents to be resources only for a certain role of user, since they can potentially include sensitive information.

Please allow access to the dropbox to be controlled via the permissions API, such that one of the usual Drupal permissions modules can be used to set it to be accessible only to certain users. Speaking for our circumstance only, we don't need finer grained access than that, but we can't have it all open.
