I need to write an algorithm that sends a request to a remote server for Ntlm authorization (login and password) to a secure domain site and authorization through active directory. And I need to get a response from the server. My code should ignore certificates but it gives an error: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target. and I can’t install the certificate.
