tdf#149921 ucb: webdav-curl: WNT: certificate revocation check
- don't require it to be successful.
Trying to connect to a server with self-signed CA results in:
warn:ucb.ucp.webdav.curl:6796:6568:ucb/source/ucp/webdav-curl/CurlSession.cxx:946:
curl_easy_perform failed: (35) schannel: next InitializeSecurityContext failed:
Unknown error (0x80092012) - The revocation function was unable to check revocation for the certificate.
Apparently schannel wants to check by default (called with
SCH_CRED_REVOCATION_CHECK_CHAIN) that all the certificates aren't
revoked, but the self-signed CA doesn't specify how to check.
Set it to only check revocation when the way to do so actually works,
via CURLSSLOPT_REVOKE_BEST_EFFORT, which sets these flags:
SCH_CRED_IGNORE_NO_REVOCATION_CHECK | SCH_CRED_IGNORE_REVOCATION_OFFLINE | SCH_CRED_REVOCATION_CHECK_CHAIN
