title: spring saml: How is LOGOUT handled? Is it mandatory to have logout endpoint in IDP metadata xml?
body: <p>I am using Spring SAML implementation. SSO circle metadata xml was having logout endpoint which helps in local logout and global logout. But there are some other IDP's which I am interacting with and are not having logout endpoints in their metadata xml. </p>
  
  <p>How should LOGOUT be handled in these scenarios? </p>
  
  <p>Is deleting cookies of the request the only solution of this problem or is there any workaround for this scenario?</p>
  
  <p>Your help in this regard is much appreciated.</p>
