title: Single Sign-On on Spring Application
body: <p>I'm working on a web application under Tomcat on a Linux server and all clients are under a windows domain. I need to get the user account from the request to assign it the right role on my application. So to summarize I just need to retrieve the user account becasue the authentication is not required.</p>
