Here is a common scenario I would like assistance on in regards to SharePoint 2013 planning.
We have internal users and external users (external users authenticate, probably through forms or SAML / Active Directory).
We want to put a SharePoint Foundation server in the DMZ. This is what the external users will use to access documents.
We have an internal SharePoint 2013 Enterprise Edition server for our intranet and content management system.
Here is the question:
How does an internal employee working on a document share the document they are working on with the external people?
The goal here is to not MOVE the document entirely from the internal project site where the master copy is suppose to be retained and move it to some document library not at all related to the project on the external sharepoint foundation server sitting in the DMZ.
There must be some built in feature of SharePoint to retain a copy or soft link between the master copy on the internal sharepoint site with a copy that external users are able to collaborate on without the internal users. If there isn't such a feature how do you keep one copy of the truth that both external users and internal users can collaborate on and still maintain the proper organization of that document (associated with the master project document library that is only available internally).
