IMPORTANT: to apply this patch, please remove the following tables: "naval_profile", "naval_user", "user_profiles", and "user_roles".
This patch fixes bug 214 by removing UserRole.ROLE_BASIC_USER. Now, authenticated users with no roles (MandatoryUsers.USER is an example of such an user) can access all pages other than those reserved for specific roles (e.g. UserRole.ADMINISTRATION). Furthermore, this patch also improves support for disabled users by: (1) using the Spring Security support for managing such users and (2) displaying two types of error messages in the login page depending on the type of error ("User disabled" or "Incorrect authentication").
