Good catch; however, the problem might need a slightly different fix; in 
fact, yours prevents rwm_response from aborting the operation by forcing 
an "unwilling to perform" based on the contents of the referral/matched.

However, this is probably conflicting (as in many other cases in 
slapo-rwm(5)), with the fact that some operations (e.g. extended) do not 
return response directly, but delegate the frontend; or, like the bind 
operation, only return unsuccessful results directly, and delegate 
successful responses to the frontend.
