// Allows a caller to assume an IAM role decorated as the SAML user specified in
// the SAML assertion included in the request. This decoration allows Lake
// Formation to enforce access policies against the SAML users and groups. This API
// operation requires SAML federation setup in the caller’s account as it can only
// be called with valid SAML assertions. Lake Formation does not scope down the
// permission of the assumed role. All permissions attached to the role via the
// SAML federation setup will be included in the role session. This decorated role
// is expected to access data in Amazon S3 by getting temporary access from Lake
// Formation which is authorized via the virtual API GetDataAccess . Therefore, all
// SAML roles that can be assumed via AssumeDecoratedRoleWithSAML must at a
// minimum include lakeformation:GetDataAccess in their role policies. A typical
// IAM policy attached to such a role would look as follows:
