I'm trying to use basic form validation to authenticate people before they use my Plesk deployed Tomcat application. I updated the tomcat-users.xml file with the name and role I wanted, then updated the web.xml for my applicaiton to use basic authentication. This works just fine on my development machine. However, when I try it on the box I have Plesk running on, it does not work. Is there a different type of authentication I need to use?
