title: Spring security: External Authorization
body: <p>I successfully completed login module of my application using spring security's inbuilt authentication &amp; authorization mechanism.But later i was told to check if i can integrate <code>WSO2</code> (<code>SOA solution as external Authorization mechanism</code>) with <code>Spring</code> security so that i can use Spring security's authentication mechanism alone and <code>WSO2</code> for authorization instead of using Spring security provided Authorization.</p>
  
  <p>I did search &amp; read the documentation and i could get details about using External authentication with Spring security &amp; nothing about External authorization.I would like to know if i can do the same and also how i can do it.Any pointers will be really helpful for me.</p>
