User Authentication - AD Group in Group

Hey,

following Problem:

I have a Active Directory group "G-SSL-IT". In this group are other groups ( e.g. IT, Support etc.) . In XG i´ve imported the group "G-SSL-IT". In AD I manage the users only in the sub-groups. 

For Example: 

Bob --> G-IT --> G-SSL-IT

Dave --> G-Support --> G-SSL-IT

All these Users should have SSL Access. 

When the User is in a Sub-Group, in XG the User has group: "open group" --> User Portal no SSL 

When the User is directly in group G-SSL-IT, all is working fine, User has group: "G-SSL-IT" --> User Portal with SSL

Is it possible to work with AD group nesting in XG?

cheers

Danny
