Proxy issues?

[PickledKitty]

While trying to debug user login failure using basic auth, I found that the loginpage_hook() function doesn't return anything for isset($_SERVER['PHP_AUTH_USER']) && isset($_SERVER['PHP_AUTH_PW'], and so never gets to the 'has credentials' part, instead returning an error of invalid login and nothing further.

I assume you can still log in through the login/index.php page when a user's authentication method is basic?

My Moodle uses a proxy server. Do you think that has anything to with it?

Really struggling here! How can I troubleshoot? Any ideas?

It sounds like you have already debugged it enough, if the basic auth headers are not getting through to php then it must be a problem further upstream, either in the php setup or in the reverse proxy in front of it.

There is an admin setting auth_basic | debug which you can turn on which dump debugging into extra X- response headers but it won't tell you much you don't already know.

Yes, but as always test it
