Im looking on how to verify the in_response_to id of the authentication response. Most examples use allow_unsolicited to ignore this so it is a bit hard to find good sources. Many of those examples also reference to a "built-in cache for authn request ids in pysaml2", but I can't find any usage of that anywhere. I have tried to do this myself by just saving the ids I send to a dictionary and then give them as a parameter to parse_authn_request_response. My question is this. How should this really be done? Is there a built in cache or what is the recommended way of verifying the in_response_to ids? Thank you -- Stefan
