// Creates an IAM resource that describes an identity provider (IdP) that supports
// SAML 2.0. The SAML provider resource that you create with this operation can be
// used as a principal in an IAM role's trust policy. Such a policy can enable
// federated users who sign in using the SAML IdP to assume the role. You can
// create an IAM role that supports Web-based single sign-on (SSO) to the Amazon
// Web Services Management Console or one that supports API access to Amazon Web
// Services. When you create the SAML provider resource, you upload a SAML metadata
// document that you get from your IdP. That document includes the issuer's name,
// expiration information, and keys that can be used to validate the SAML
// authentication response (assertions) that the IdP sends. You must generate the
// metadata document using the identity management software that is used as your
// organization's IdP. This operation requires Signature Version 4 (https://docs.aws.amazon.com/general/latest/gr/signature-version-4.html)
// . For more information, see Enabling SAML 2.0 federated users to access the
// Amazon Web Services Management Console (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_providers_enable-console-saml.html)
// and About SAML 2.0-based federation (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_providers_saml.html)
