You have configured the service provider for SAML 2.0.
You have configured a trusted identity provider for the service provider.
Once you have configured an SAML 2.0 service provider to trust an identity provider, you designate which resources are protected by SAML 2.0 by assigning the SAML 2.0 login module to the authentication stack.
Once you have configured how a resource is protected by SAML, ensure that the identity provider can fulfill the requirements you configured.
