That was just a suggestion, but I do agree this is more a hack than 
anything else. Plus after having checked the ou=config file, I don't 
even thinhk it's necessary.

I totally buy the fact that implementing partial replication would solve 
the issue.

The ou=config DIT starts with :

version: 1
dn: ou=config
ou: config
objectclass: top
objectclass: organizationalUnit

dn: ads-directoryServiceId=default,ou=config
objectclass: top
objectclass: ads-directoryService
ads-directoryserviceid: default
ads-dsreplicaid: 1

As we can see, each configuration is specific to a service, here 
"default". If we correctly name the instances so that there is no 
possible confusion between them, then we should be safe even if we 
replicate everything.

The thing we have to solve is about the instance name : how dos the 
server get its instance name ?

I must admit that, even if I worked on those thing in the past, it's not 
really fresh in my mind...
