title: SharePoint Integration for Single-sign On
body: <p>Let me preface this with I am an experienced .NET developer--but I have not yet worked with SharePoint, so this question relates directly to SharePoint and its features.</p>
  
  <p>I'm working on a project that requires integration with SharePoint to the extent that a user can click some kind of redirect link that would allow them to authenticaate to my application without having to sign in every time.</p>
  
  <p>I'll need the ability to specify which SharePoint users will have access to my application and then show those users a login. (So maybe 2 web parts, one for an administrator to assign SharePoint users to my app, and 1 for the actual app link?)</p>
  
  <p>For the SharePoint-experienced devs out there, what are your thoughts on how to do this in the most simple, non-intrusive way?</p>
  
  <p>Thanks for any help you're able to provide.</p>
