I don't have a live server available for testing, but I prepared simple local test:
- Download http://web.hisoftware.cz/sob/tc/ftps-san-test.7z and unpack it to some empty directory
- Add contents of host.sample.txt to system hosts file (usually C:\Windows\System32\drivers\etc\hosts)
- Edit paths to totalcmd.exe and openssl.exe in .bat files
- Run start-server.bat to simulate local FTP server (*1) with implicit SSL using openssl.exe
- Run start-totalcmd.bat to start TC with local ini files with configured trusted test CA
- Connect to ftps://test.example.net:990/ (*2) - TC will accept certificate -> correct
- Connect to ftps://example.net:990/ (*2) - TC will not accept certificate automatically -> bug
(*1) TC will get stuck after USER command, because it's not actual working FTP server, but it's enough to test certificate verification
(*2) There are connections saved in wcx_ftp.ini
