Microsoft recommend that you use fine-grained permissions only when a business case justifies it. It also recommend that you avoid breaking the permissions inheritance as infrequently as possible.
In this session we will use a simple business case that requires usage of unique permissions. We will dive deep into the SharePoint infrastructure to learn what is going on ‘behind the scenes’ and where are the limitations. While resolving our business case you will learn the simplest way to programmatically break the role inheritance on item level and how to manage it. Then you will learn why and when this simple scenario fails and what to do about it.
Through the whole session you will be presented by available options and possible alternatives.
At the very end we will try to break the limits and see what happens.
