Sunil,

The certificate available from https://www.nldap.com seems to contains
encoding errors - at least according to asn1dump.

The error seems to come from the securityAttributes
(2.16.840.1.113719.1.9.4.1) certificate extension. However I seem to be able
to decode the certificate - but my version isn't 100% in synch with CVS.

Looks like there is some problem with the Mono's
System.Security.Cryptography.X509Certificates.X509Certificate class.
I tried to create a certicate object using CreateFromCertFile method and a
ASN1 DER encoded certicate file  ,but its throwing exception. I did the same
thing on windows using MS .NET with the same certificate file and its
working. Below is the code snippet:-

try{
X509Certificate cert = X509Certificate.CreateFromCertFile(certfile);
}Catch(Exception e)
{
        Console.WriteLine("Error:" + e.Message);
        return;
}

On linux it throws following exception:-
Error: Input data cannot be coded as a valid certificate.

Regards
Sunil.

Thanks very much.

I have made a little test trying to negotiate the Handshake protocol
against the www.nldap.com using .NET 1.0 and the SSL/TLS libraries
sources from my local tree, with success, i will try to make the same
test using mono, and update the mono cvs sources as soon as possible.
