I have an issue with CoRD not working properly

I have an issue with CoRD not working properly. It keeps on failing to connect to a server that requires Network Level Authentication. I have no idea why this happens because there are no error messages or warnings. It seems that Network Level Authentication is not supported by CoRD but I was hoping it can issue a warning and detect Network Level Authentication. Is it possible to create a box containing causes and solutions?
Please suggest possible solutions. Thank you.
