Ahh, I dropped a right clanger there, when I said SID I meant RID, it 
would seem that when you join a DC to a domain, idmap.ldb does not get 
replicated to the new DC and so the RID's could be and probably are 
different. This is not really a problem, just copy idmap.ldb from the 
original DC to the new one.
