WS Security in Domino

Hi good people

Im working on an integration project whereby WebSevices will be used for integration layer and lotus notes applications will be consuming the services. On the service provider side WS Security with SAML implementation is employed. The question is whether domino/lotus notes supports this framework(WSS/SAML)? And if it doesn’t what could be the suggetion to overcome this hurdle. We need to find a solution urgently. Any help will be appreciated.
