Thanks owaino, for this article. Looking at the OAuth2 proxy GitHub home, I couldn't find any information about which organisation is behind it or who is supporting its development. With many open source projects gettting abandoned after some time, I'm conscious of using something that is not guaranteed to be properly maintained and updated in the future.
I checked out the Dapr OAuth2 middleware component but there's nothing indicating that it is still in alpha. As a matter of fact, it's documented in the stable 1.11 release. I can see the issue you've raised has been closed as statle. I was wondering if you had a chance to give this another try since the article was published.
