Actually, my “other application” is a desktop app, not a web app. I don’t think discourse-auth-proxy will work in that case.
On the DiscourseConnect page, one of the first statements is this:
Many sites wishing to integrate with a Discourse site want to keep all user registration in a separate site. In such a setup all login operations should be outsourced to that different site.
This is the exact opposite of what I want to do: I want to outsource all login operations to Discourse. Is there a way to use DiscourseConnect to do that?
