title: Any pointers on implementing oAuth Server on DNN?
body: <p>I need to build an ecosystem of online tools (these tools are on various platforms like Moodle, Website Baker, ASP.Net, php, etc, some already built, some purchased from other vendors and some to be built), where I want a single login that the end user should have.</p>
  
  <p>These tools, standalone, have their own login mechanism in place at the moment.</p>
  
  <p>I am planning to build a central system on DNN where users register and this system exposes an oAuth service that other systems use to authenticate users against. </p>
  
  <p>I am considering DNN (DotNetNuke) platform for the following reasons:
  1. I am an ASP.Net developer and familiar to some extent with DNN (Not a whole lot, but enough to know that it has the concept of providers and modules that I can customize as per my needs).
  2. I will need a shopping cart and a registration system which I am hoping to get some ready-made third party solution.</p>
  
  <p>WHAT I NEED INPUTS ON:
  Is there some DNN component out there already that exposes oAuth authentication from a DNN site? I am looking to implement something similar to what Google has implemented for it's oAuth interface.</p>
