Unable to connect to Sharepoint site over https using Sharepoint List Source task from CodePlex

I have downloaded and installed the Sharepoint List Adapter from CodePlex from the link: http://sqlsrvintegrationsrv.codeplex.com/releases/view/17652

However I am unable to connect to sharepoint site using https using Sharepoint List source
I see the following error while the validation fails:
Error "Error at Data Flow Task [Sharepoint List Source for RFCLists [650]]: System.ServiceModel.Security.Messag<//wbr>eSecurityException: the HTTP request was forbidden with client authentication scheme 'Ntlm' "

However when i access the same sharepoint site with the HTTP instead of HttpS, it succeeds without any problem and I am able to see the data as well

Is there any known documented issue while using the Sharepoint List source with htpps? If not, can you please let me what might be going wrong here?
