Versions older than 0.16.0 did not verify that the LDAP server's certificate matched the host it was supposed to be connecting to. This has now been assigned CVE-2017-17718 by MITRE. Older versions did not perform any kind of validation at all, but it was properly documented as such. Based on the changelog I believe this to have changed in 0.10.0 by verifying the certificate's trust chain. https://github.com/ruby-ldap/ruby-net-ldap/issues/258 Cheers, -- Raphael Geissert
