/**
 * Generates a SAML v2.0 Authentication Request and performs a browser POST

 *            issuer of the SAML v2.0 AuthnRequest
 * @param idpDestination
 *            required eID IdP destination
 * @param spDestination
 *            Service Provider landing URL where the IdP will post the SAML2
 *            Response to.
 * @param relayState
 *            optional relay state
 * @param spIdentity
 *            optional Service Provider Identity. If specified the
