title: How can we make a website authenticated user autologin to wordpress?
body: <p>I have a Web application where the users will be authenticated before they use it. The help documentation for this application is maintained using Wordpress installed on a different server (If needed the Wordpress instance can be installed on the same server also). In order to access the documentation also, user must be authenticated and now this is done using a Wordpress plugin.  </p>
  
  <p>Now i want to make the authentication process common for all. i.e User comes to the web application, then login to use the application and they can click the 'documentation' link within the application and user automatically login into the Wordpress also. How can i implement this?</p>
