spring security - Only SAML token validation -

I have a SP (applied to the service provider using Spring SAML), I want SP another The application will send authentication SAML token to the service. Now I need to confirm the token against IDP at the end of cancellation service. How can I get this?

Any help will be apreciated

The mechanism in standard SAML profiles is that of the IDP server Provides recognition of claims against SAML issued. Validation is usually done by the recipients of the token - it was done using a trusted certificate to validate and validate the XML signature on the claim.

There are additional standards which write and use the claim of SAML for such use, for example, for example, for example, but it becomes very fast complicated.
