SAML authentication

Hi All,

 I had a question on SAML. I know SAML can be used for the SSO authentication .

But in my project we already have an application as 'OneLogin' , this helps us to authenticate for the required products and sends back an SAML reponse with few attributes. I m unable to understand how the existing SAML widget of MENDIX can consume this SAML reponse and create the session. I m bit confused with this. Could any one help me on this?
