I was able to forward a radius request with 'suffix' in the authorize section. But now, the use case has changed, when arriving in the authenticate section, a perl authenticate function is started, and tries authentications (Web API request) against 3 OTP Servers. If one of the 3 OTP Servers return ok, the authenticate perl function return RLM_MODULE_OK. But if all authentications against OTP Servers fail, we would like to forward the request to another radius server. Is it possible?
