Authentication and IDM technologies are at the core of our system and network security. Whether it's logging into our personal laptop, or a corporate website, authentication is how we define roles and privileges to our users and ourselves. Opensource has a number of IDM offerings, as do corporate offerings. In this talk, we'll explore some of the history of these projects and what they offer, the direction that authentication and security is moving in. We'll also introduce Kanidm, a new opensource IDM system that has been created to adapt to these changes in IDM and security, and talk about what it's achieved in a short space of time, and what the future holds for it.
