This makes us scale better with many simultaneous winbind requests, some of which might be slow. This implementation breaks offline logons, as the cached credentials are maintained in a child (this needs fixing). So, if the offline logons are active, only allow one DC connection. Probably the offline logon and the scalable file server cases are separate enough so that this patch is useful even with the restriction.
