Re: NO_SUCH_OBJECT

["Kurt D. Zeilenga" <Kurt@OpenLDAP.org>]

I assume that the base object of your search was located but
no objects within scope matched the filter.  In this case,
an empty set of entries and result success is quite appropriate.

If this assumption is incorrect, please detail the operation
in more detail.  In particular, duplicate the operation using
ldapsearch(1) and describe how ldapsearch(1) (and the C SDK)
handling differs from your client (and the Python SDK) differs.
