SAML 2.0 authentication strategy for Passport

/**
 * Simple in memory cache provider.  To be used to store state of requests that needs
 * to be validated/checked when a response is received.
 *
 * This is the default implementation of a cache provider used by Passport-SAML.  For
 * multiple server instances/load balanced scenarios (I.e. the SAML request could have
 * been generated from a different server/process handling the SAML response) this
 * implementation will NOT be sufficient.
 *
 * The caller should provide their own implementation for a cache provider as defined
 * in the config options for Passport-SAML.
