“AuthenticationRequest” generation

request = LASSO_LIB_AUTHN_REQUEST(LASSO_PROFILE(login)->request);
request->IsPassive = 0;
request->NameIDPolicy = g_strdup(LASSO_LIB_NAMEID_POLICY_TYPE_FEDERATED);
request->consent = g_strdup(LASSO_LIB_CONSENT_OBTAINED);
request->ProtocolProfile = g_strdup(LASSO_LIB_PROTOCOL_PROFILE_BRWS_POST);
