I have a JBoss application on a aws EC2 cloud instance and I've had disable all my individual war authentication in WEB-INF/web.xml which use login-config.xml because they can't reach our LDap servers inside our network. So I was wondering if there are other "authentication" options that I can use...
You could use the UsersRolesLoginModule. If your VM also has a database, you could use DatabaseServerLoginModule (in a pinch you could even use that with the built-in HSQLDB, but it is more of a pain to set it up).
