[Samba] Should BDC have same local SID as the Domain SID?

[Alex Crow]

Hi,

Come up against this in 3.6.5. I can join a BDC to a domain, and it gets 
the Domain SID from the PDC, but keeps its local machine SID.

Is domain SID=local SID expected or required on BDCs, or should I just 
let the BDCs keep their unique local SID, or, in fact, does it not 
matter at all?

Obviously I can force the local SID to the domain one with net 
setlocalsid, just not sure what is the "correct" procedure.

Cheers

Alex
