The auth issue is the same exact issue for the lineage 2 version of the leaks , password authorization is not handled via Auth anymore in new bins, it is handled via a external relay, then result is passed back to auth, so you need a PortalAuth implementation (PAServer in configs ), savior has a open source version released, that is why you can pass login with any info, and it always hits the server as account 0
Where can I download the open source version?
