body: <p>How can I provide login feature to a Jekyll site? </p>
  
  <p>I'm not sure if I am asking the correct question. Basically, I'm setting up a Jekyll blog for an intranet, and when any person (who connected to the intranet) comments on the blog, I want the site to use Windows's username as the display-name of the comment. In this way, I would know which comment is posted by which user (connected to the intranet), and I don't want the commenters to choose any other name as display-name to discourage trolling. Can it be done? </p>
  
  <p>I was thinking if I could force the poster to login before commenting (and verify it Windows's athentication somehow), then maybe that username can be used as display-name. I'm not sure if that is possible, as I don't know if Jekyll provides that much flexibility.</p>
  
  <p>I'm using Disqus as comment-provider. I may switch to a suitable comment-provider if required.</p>
