[Samba] how to manually specify domain controllers

Thank you for your reply. I have FreeRadius installed on both Samba servers and authenticate to Active Directory domain controllers(not the local Samba server). In this scenario, there is possibility that both Samba servers pick up the same domain controller(using DNS resolution) to authenticate which could cause uneven load problem.

I see you have had no replies as of yet.. Can you clarify the scenario - is
freeradius installed on both of your samba servers, and configured to
authenticate against the local samba server for active directory
integration? Or is the scenario something different?
I use freeradius here; each of my DCs has freeradius installed and
configured to use the local samba server. But it's down to my radius
clients to pick the correct DC / radius server to authenticate against, if
I want to spread the load..
