OK, I have found out how to change this:
http://technet.microsoft.com/en-us/library/cc816871(v=WS.10).aspx

However, this suggests that there is a bug in our net ads leave code.

Consider the following:

1. Administrator adds a new DC to the site. However, replication has
not yet occurred or has not yet completed to the new DC.

2. Someone tries to leave the domain from their Samba member server.
They get a list of DCs with the new DC first in the list.

3. Leave fails because that DC does not yet know about the member server.

Shouldn't we try the next DC in the case of a failure until we exhaust
all DCs or we get a success?
