DSCL NestedGroups

I have a scenario where I need to append an Open Directory group as a Nested Group member of a local group. I’ve been able to successfully do this manually using the Directory editor- but I’m going to need to do this on 70 machines, and doing this individually thorugh the GUI would take far longer than I have to offer. All the clients & the server are running Snow Leopard, and I’m hoping to have something I can push out using ARD.

Any help?
