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..
