I'm not so sure it's broken.  I haven't gone thru all of it yet, but as
far as search is concerned, it seems to me that the right value is
checked before and after mapping, and that ldap_back_op_result() is only
called when retry is no longer an option.  I'll investigate a bit more
carefully; I might add some #ifdef'd code to test those error
conditions.
