It might not be as soon as some internal searches rooted at <searchbase> 
with scope "base" need to be performed, because in this case they would 
actually return the rootDSE instead of the context entry of the database 
you're trying to replicate.  This is a mere speculation, I haven't 
looked at the code yet.
