ownCloud Infinite Scale - Identity, Roles and Permissions

<!--HTML-->ownCloud Infinite Scale (oCIS) will be used in many different environments. Many of those environments already have existing role definitions. To best support the individual existing definitions we designed and implemented a system which is open enough to be fitted to the environment. oCIS extensions will also benefit from that, because they can use this system for their permissions instead of implementing their own. This talk will give an overview over the concepts, considerations, decisions we have made.
