slapd doesn't know in advance how many results can be returned. It knows
how many potential candidates were generated by index lookups, but this
number may be much larger than the actual result set. In particular, the
result set may be much smaller due to ACLs, as well as actual filter
comparisons. It would be a security violation to disclose the existence
of entries that the user is not permitted to see.
Rejecting this request.
