For anyone curious, this test shows how to use back-config and syncrepl to 
dynamically configure and populate a server.

Two stub entries (cn=config and olcdatabase=config,cn=config) are slapadded 
to initialize the master and slave configurations. Then ldapadd/ldapmodify 
are used to load the syncprov module, add a syncrepl consumer to the config 
database, and add the syncprov overlay to the config database on the master.

Then ldapmodify is used to start a syncrepl consumer on the slave's config 
database.

The rest of the script adds schema, a database backend and content for the 
backend on the master, all of which get replicated to the slave.

The dilemma of how not to wipe out the consumer configuration once the 
complete master configuration is replicated onto it is solved with this 
trick: the master has both a provider and a consumer configured on it, and 
the consumer points at the master. The syncrepl config handler checks to see 
if its providerURI matches any of the current server's listenerURIs. If 
there's a match, the config is a no-op. (It gets parsed but no consumer task 
is triggered.)
