Question

My web application is using Spring Security but it returning a BadCredentialsException when processing a form based login. The credentials entered by the user match exactly whats in the database and I don’t see the Spring code that compares the j_password value against that of the Users.getPassword from the db, any ideas on how to troubleshoot this? I want to see what its comparing to throw the BadCredentialsException. When I use a hardcoded Below is an outline of my implementation hoping someone can spot my error. Thanks for the assistance!

public static Users getLoggedInUser() {
    Users user = null;
    Authentication auth = SecurityContextHolder.getContext().getAuthentication();
    if (auth != null && auth.isAuthenticated()) {
        Object principal = auth.getPrincipal();
        if (principal instanceof Users) {
            user = (Users) principal;
        }
    }
    return user;
}

UserDetails Implementation (Users.java):

public class Users implements Serializable, UserDetails {
    public Collection<GrantedAuthority> getAuthorities() {
     List<GrantedAuthority> auth = new ArrayList<GrantedAuthority>();
    auth.add(new GrantedAuthorityImpl("ROLE_USER"));
    return auth;
}

}

user-service-ref=”userManager” (UserManagerImpl.java):

 public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException, DataAccessException {
    Users user = null;
    try {
        user = userDAO.findByUsername(username);
    } catch (DataAccessException ex) {
        throw new UsernameNotFoundException("Invalid login", ex);
    }
    if (user == null) {
        throw new UsernameNotFoundException("User not found.");
    }
    return user;
}

It looks like you are storing cleartext password in the database, but using a passwordEncoder in spring-security configuration, which encodes the received password before comparing against the stored one.
