The Session will cover all advanced topics that you need to know about when developing high complex security solutions for your SSAS database. Those topics include cross-level dimension security, multiple role combinations and foremost dynamic security setups. All of them are designed for different business requirements but no solution fits them all. The different approaches will be examined on their impact on caching, connection time and also maintenance and in the end you probably understand why it can sometimes make sense to have 2000+ dynamic roles in your SSAS cube! A major part of the session will be dedicated to dynamic security using SSAS assemblies. Especially for complex requirements this is often the last hope. This session will guide you through the most common and uncommon pitfalls that you will encounter and show how to work around them.
