SSO between ADFS 2.0 and AS-ABAP 7.02

Dear experts,

I am trying to configure SSO for users accessing WebDynpro applications on an AS-ABAP 7.02 backend. They access these apps with Internet Explorer. All users are authenticated against ADFS 2.0, and I would like to configure SAML2 based SSO with ADFS 2.0 as the IdP, while the ABAP backend act as the service provider. However I find that there're hardly any documents available for this process, and none of the related questions asked on SDN gets very helpful answers.

So can someone please kindly let me know if this is possible at all? If possible, can you please kindly share some documents or guides on how this can be achieved?

Thanks very much for your help in advance, and any help or hint is appreciated.

Best regards

Luis
