[Samba] SambaSID's on PDC/BDC

[Christopher Perry]

I have a server acting as a PDC, and another server acting as a BDC. 
When I run 'net getlocalsid'
 on each, they return different numbers. If I run 'net getlocalsid 
domain_name' on the BDC, it returns the PDC's sid.

Is it import for each machine to have the same SID?

Thanks,
Chris
