CURLOPT_SSL_VERIFYPEER - multiple paths

From: Vermeire, Baudewijn via curl-library <curl-library_at_cool.haxx.se>
Date: Thu, 2 Jul 2020 09:40:24 +0000

Hello;
in the past few weeks we had a certificate issue on your webservices.
Our desktop application did not handle well; i mean the certificate issue was not reported at all.
I am now testing the connection by setting
curl_easy_setopt( theCurlHandle, CURLOPT_SSL_VERIFYPEER, 1);
as well as debug flag.

It reports error
X509_V_ERR_SELF_SIGNED_CERT_IN_CHAIN, but investigation learns that
certificate has 2 paths which 1 of them if valid and other has 'self signed cert'.
How can is setup curl lib so that it 'VERIFYPEER' , so that connection succeeds if there is still 'a valid path';
despite some that having error?

best regards
