I am having difficulty connecting to an SSL server that requires the FULL client certificate chain to be sent.

Some basic information: This is an ASP .NET application which is successful connecting to SSL servers not requiring the Full Certificate Chain, however, as soon as it tries to use one that does require it, the connection fails during the SSL handshake. The error thrown on my side from the Mentalis library is, "The other side has sent a failure alert". The error on the server side, Java OpenSSL BTW, is "Invalid Certificate".

I have looked into the CertRequestEventHandler, but I cannot see how to sendthe full certificate chain using this function.

I appreciate any help anyone could be.

Thanx in advance.
