git access using SSL certificates

Hi,

I have configured a bare Git repository over HTTPS and client needs to have a SSL certificate-key to access the repository. I am able to access this repository using Firefox by loading client certificate in the Firefox, but it is not working with git command line client. 

I tried setting http.sslCert and http.sslKey configuration options, but it is not working. Following were steps in accessing the repository. Am I missing something in my configuration? Any pointers on how to share git using SSL certificates would be really helpful. 

Thanks, Shantanu.

* Try git-clone using HTTPS without client certs

* Try git-clone using ssh

* Change git remote url 
{{{

* Try git-pull with HTTPS without certs 
{{{
mercury:fifa2010 shantanu$ git pull

* Try git-pull using certificates
