Hi,

I'm trying to configure for the first time SAML2.0 for an application but I'm getting the below ERROR. How can I overcome this?

thanks..

Umut,

Use a browser plugin, such as saml tracer, to see what the saml looks like for the request.

This error means that the saml request is either incorrect, or the service metadata does not match the request. For instance, the request is trying to reach a different binding but you only have POST configured (or some mismatched configuration like that).
