iis security : SSLv3 with certificate issued by Intermediate certificae authority

after enabelling SSLv3 (Require client certificate) , the authentication
proccess fails.
I know that while the SSL/TLS Handshake, the server send a
certificateRequest message that prompt the client browser for a valid
certificate.

The CertificateRequest message include only Root CA certificates from the
locale machine store.

I am trying to authenticate to the web server with certificate issued by
Intermediate certificae authority, which the server trust it's root CA
certificate - without a success...

How can I configure the IIS to accept connection with client certificates
issued by the Intermediate certificae authority without the need to add the
Intermediate certificae to the trusted list (which is the basic idea by
building the trust chain)?

thanks.

Just because I trust the Root CA, it does not mean I trust certificates
issued by an intermediate CA...

Isn't it the default idea when the server trust on root CA, it shoud trust by
default on all the issued certificates from that CA?

If I trust RootCA, then I trust all certificates signed by RootCA.

That does not automatically mean that I trust all certificates signed by
IntermediateCA.

Ok,
So, In order to enable Smart card logon to a windows domain enviernment I
know that i need to update the NTAuth Object with all the issuers
certificates that i want to trust them.
What should i do in my situation, when I want to enable sslv3 authentication
on IIS Server? Should i add to the certificate store all the issuers
certificates that i want to trust on, even then they came from the same Root
CA?

Is there any other solution?
