Search guard max header size

Many month ago, I opened a bug in github about maximum header size.

I’m using proxy authentication and we have many groups, so the roles_header can be quit long, and it reaches SG maximum values. So I opened a bug in github and it was resolved. But since all data has been removed, all git history is new, I’m unable to find what the resolution was. I’m thinking that a settings was defined that allows a bigger maximum header size, but I’m not sure, and browsing through the code didn’t return any thing.

Does someone remember what was done ?

Not sure about the original issue but I guess you need to adjust http.max_header_size (which is a ES and not a SG config option because SG itselft does not have any limits with regards to max header sizes). Default is 8kB. See https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-http.html for more information.
