+Vaadin 7 + Spring Security (base authentication)
+------------------------------------------------
+
+Vaadin 7 is easy to integrate with Spring Security. You should configure only
+2 files. First - web.xml and second one spring-security.xml (user
+credentials and security settings). This is a small example on how to use
+base form for authentification.
