1760	Client cert verification not working with Openssl 1.1.1b - working on 1.0.2r	scaarup@…		"Hi guys.

If I build Nginx with OpenSSL 1.1.1b, client cert verification is not working. Always resulting in:

2019/04/02 21:18:55 [info] 29916#0: *10 client SSL certificate verify error: (26:unsupported certificate purpose) while reading client request headers, client: <masked ip>, server: <masked-hostname>, request: ""POST /endpoint/jokum HTTP/1.1"", host: ""<masked-hostname>:4000""

Configuration:

{{{
                ssl_client_certificate /etc/nginx/root.pem;
                ssl_verify_client on;
                ssl_verify_depth 3;
}}}

If I then build Nginx with OpenSSL 1.0.2r, it works fine. Same configuration on same server.
