Apache Shiro for securing REST api

Question

I am attempting to integrate Shiro in my spring mvc application. The authentication is backed by a LDAP server and i am able to successfully authenticate against the ldap server and obtain a cookie.

What I am not able to perform is to then use this cookie in subsequent requests and get results. Attempting to use the cookie gives me a HTTP 302 to perform authentication again. For example: GET on ( rest/assets/list ) with header Cookie: JSESSIONID=abcd redirects to (rest/login)

Is this the right strategy to secure the api ? The api is being used by a AngularJS app and i would like to get user group based authentication enabled before I add CRUD ability.

Any pointers would be useful.

Source code as follows:

applicationContext.xml file is as follows

 <beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

            /rest/** = user
        </value>
    </property>
</bean>
</beans>

LDAPRealm.java code is

public class LDAPRealm extends JndiLdapRealm {

@Override
protected AuthorizationInfo doGetAuthorizationInfo(PrincipalCollection principals) {
    String username = (String) getAvailablePrincipal(principals);
    return super.doGetAuthorizationInfo(principals);    //To change body of overridden methods use File | Settings | File Templates.
}

@Override
protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
    return super.doGetAuthenticationInfo(token);    //To change body of overridden methods use File | Settings | File Templates.
}

}

LoginController.java is

@Controller
public class LoginController {

@RequestMapping(value = "/login", method = RequestMethod.POST)
public void login(@RequestBody UserCredentials user) {
    UsernamePasswordToken token = new UsernamePasswordToken(user.getUsername(), user.getPassword());
    token.setRememberMe(true);
    SecurityUtils.getSecurityManager().authenticate(token);
    Subject subject = SecurityUtils.getSubject();
    subject.getSession(true);
}

@RequestMapping(value="/logout")
public void logout() {
    Subject subject = SecurityUtils.getSubject();
    SecurityUtils.getSecurityManager().logout(subject);
}

}

The logging from apache shiro is

Answer 1

The Idea behind REST is that it is Stateless so, if you create a session with the client you would break the priciples of an RESTful API. I would recommend to use Spring Security, you can find a simple example here: http://spring.io/guides/gs/securing-web/. It will take you about 5 - 10 Minutes and you can then use it in your project.

Also there is a simple guide for connecting to an LDAP system: http://spring.io/guides/gs/authenticating-ldap/

UPDATE: Saw your comment on your question, I would suggest you to answer your question with the result you come up with.
