(00:17) K Scott asks Dominick about the subject of his talk at NDC. Dominick runs through the upcoming changes in Web API authentication, including an overview of CORS and token based authentication.

(05:13) Rob describes how he’s seen people breaking their sites and services across multiple domains and subdomains. He explains a problem he’s currently running into with older releases of Internet Explorer. Dominick explains more about how CORS works and talks about options for working with older browsers – either sticking with JSONP or putting services in the same domain.
(08:15) Jon asks how security token service relates to more well-known terms like OpenID and OAuth. Dominick explains some of the history and challenges OAuth has encountered. As a result, the OAuth spec is really just a collection of patterns rather than a strict specification.
(11:19) Jon asks Dominick how he implemented the OAuth spec in his Authentication Server implementation. Dominick gives examples of how the spec is very open – for instance, there are 69 occurrences of the word MAY in the spec. He says he’s been advocating for a minimum profile.
