When I copy-paste that script, "php -l" eventually shows me three lines
with syntax errors that can be fixed by adding some parentheses.

Unmodified, you will probably get a http 500 back from the server. That
would lead to this error message.

"php -l", or the (php-running) server error log should point at the
lines. Then you can fix them while adding your own password-verification
and server-selection code.

That's where to find the php errors, then.

http://wiki.nginx.org/MailCoreModule#Authentication describes what http
request nginx makes, and what response it expects.

The GET and Host: lines come from your auth_http configuration.

The Auth-User: and Auth-Pass: lines come from your mail client.

I suggest you mimic the nginx http request manually, using something like

curl -i -H 'Auth-User: whoever' -H 'Auth-Pass: whatever' http://example.com/auth

to confirm that you get the correct "pass" and "fail" responses from
your auth script. Once that is working, you can test the nginx setup.

Good luck with it,
