Hello Atul,
As far as I remember ADFS does not allow to add a relying party that has endpoint URLs with http protocol. Using https only is recommended by the SAML 2.0 stadard. We allow http access only for test purposes and also do not recommnd to use it in productive environment. At the end it is a limitation of the ADFS product and there is nothing SAP can do to solve it. Please contact the support of Microsoft for further help.
Regards,
Dimitar
