Enable DMS usage without the necessity of being a registered user in SharePoint

Please find more context within the attached file.

This concerns the most requested feature within our client-pool: Enabling a manner of communication between de BC-application and SharePoint, in which BC-users are not required to be registered users within the SharePoint-site that is being used by the DMS module. This would completely shield documents from access by users who are not authorized to access them from the BC-application, that would otherwise be approached via the SharePoint-site URL. As such, it fully upholds whichever has been configured in terms of permission sets and Access Controls in BC. Furthermore, it increases the overall manageability of access and authorization, by requiring the administrator to simply configure and maintain DMS authorizations on the side of the BC-application.
