Am having one SP which support WS-Fed standard protocol and IDP which supports SAML2.0 protocol. SO how to use these SP and IDP. any suggestions .. thanx in advance
Agree with @Eugenio.
Unless you have a very specific use case, rather use something like ADFS or IdentityServer or Auth0 that supports both protocols and use that as a bridge i.e. let the product do the work.
So the path is: SP --> WS-Fed --> Product --> SAML --> IDP.
Just to re-iterate: doing this yourself is non-trivial.
