An LDB request interprets an empty attribute list as a request for no attributes, but LDAP interprets an empty list as a request for all attributes, and ["1.1"] as a request for no attributes, as per RFC4511:188.8.131.52(SearchRequest.attributes). We need to convert  to ["1.1"] in the ildap module before the request goes out.
