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 RFC4511:220.127.116.11(SearchRequest.attributes). We need to convert  to ["1.1"] in the ildap module before the request goes out.
