Hold on.

LDAP_CONTROL_PAGEDRESULTS requires to be sent LDAP_CONTROL_PAGEDRESULTS
in the search response.  Does the frontend do that?  back-bdb does it
"by hand".


Clients may use LDAP_CONTROL_ASSERT to check something they want to know,
not just to ensure they don't update entries with unexpected contents.

I suppose we could evaluate the filter against an empty entry with just
the DN filled in - as if the rest were hidden by access controls.
Though since back-null is a liar - it cannot present a consistent view
of whether data are present or not - it may be better to be conservative
and always return Assertion Failed.


I don't know the requirements of the other controls/extensions.
