Howto integrate spring-social authentication with spring-security? - spring

Question

I've got a little webapp secured by spring-security using a username/password combo on a sql-db as credentials.
I now want to add facebook/twitter authentication with spring-social. Using the examples I am able to store the users credentials in my db. I'm now working on authenticating the user against his current session on my app using the following piece of code:
public String signIn(String userId, Connection<?> connection, NativeWebRequest request) {
User user = userService.getUserById(Long.parseLong(userId));
user.setPassword(this.passwordEncoder.encodePassword(user.getAccessToken(), this.salt));
this.userService.store(user);
UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(user.getDisplayName(), user.getAccessToken());
HttpServletRequest req = request.getNativeRequest(HttpServletRequest.class); // generate session if one doesn't exist
token.setDetails(new WebAuthenticationDetails(req));
Authentication authenticatedUser = this.authenticationManager.authenticate(token);
SecurityContextHolder.getContext().setAuthentication(authenticatedUser);
return "/user/dashboard";
}
The authentication works, I am not getting any BadCredential-exceptions. But after being redirected to /user/dashboard I am thrown back to the login.
I am out of ideas, a similar piece of code for authenticating the session is working after a classical signup.
Does anyone have any ideas why this happens or how to debug this?
Thanks very much in advance!

I have similar code that works for me, and also adds "remember me" support:
// lookup by id, which in my case is the login
User user = userService.findByLogin(userId);
// code to populate the user's roles
List<GrantedAuthority> authorities = ...;
// create new instance of my UserDetails implementation
UserDetailsImpl springSecurityUser = new UserDetailsImpl(user, authorities);
// create new Authentication using UserDetails instance, password, and roles
Authentication authentication = new UsernamePasswordAuthenticationToken(springSecurityUser, user.getPassword(), authorities);
// set the Authentication in the SecurityContext
SecurityContextHolder.getContext().setAuthentication(authentication);
// optional: remember-me support (must #Autowire in TokenBasedRememberMeServices)
tokenBasedRememberMeServices.onLoginSuccess(
(HttpServletRequest) request.getNativeRequest(),
(HttpServletResponse) request.getNativeResponse(),
authentication);
