Please unify CRM and SharePoint security model, so security settings on CRM Entities can be propagated on related SharePoint Document Libraries or Sites.

Not doing this means having potential security breaks. For example, users not allowed to see a CRM record could still access a SharePoint Document Library that is related to that record (for example, through SharePoint Search).

I found this suggestion from 6 years ago, and, it is just as valid if not more today. This is a huge hole in functionality and integration between the two Microsoft products. We should not have to subscribe to a third party product for this ability to support security between CRM and Sharepoint.
