DiscourseSsoConsumer is a MediaWiki extension that allows a MW site to authenticate users via the Discourse Connect Provider API (i.e., users type their passwords into Discourse). Originally released a year ago, version 2.0.0 was released yesterday. I figure it is time to give this extension its own topic here so that it is easier to find (versus the original lonely post in the SSO Provider topic: Using Discourse as an identity provider (SSO, DiscourseConnect) - #104 by mdoggydog).
It installs via
composer. Installation/configuration instructions are in the README.
