samba - May 2013 - Change groupsid AD

Hi,

I'm running Samba4 now for a couple of weeks, I'm currently stuck at the
following problem: how do I change the AD groupsid? And this without the
use of SUA in windows.

For instance I have the group NiagaraUsers
(S-1-5-21-1512407341-4132623508-1653607534-1001)  with groupsid 10020. I
just want to know how I can change this to 7002 for example.

Best Regards
Tim Vangehugten
