This replication config is not currently supported. Fractional replication 
means the consumer gets a subset of the provider's attributes. But it also 
means that the consumer can *only* have that subset. Here, cn=config needs all 
of its attributes in order to function, but the consumer code will attempt to 
delete the non-replicated ones because they aren't part of the info received 
from the provider.
