AD Groups not being resolved in SharePoint 2013 that use SAML Authentication (ADFS)

Hi,

I am wondering to see if we can use AD groups to add to SharePoint groups when using SAML Authentication.

Details:

SharePoint Server 2013 - Default Zone with NTLM, extended to extranet zone with SAML authentication only

I used LDAPCP from codeplex http://ldapcp.codeplex.com/ and am able to resolve the users through email address but not the Active Directory security groups. 

Any insight on this is really appreciated.

Thanks, SV
