This document defines a number of changes and extensions to the Policy Core Lightweight Directory Access Protocol (LDAP) Schema (RFC 3703) based on the model extensions defined by the Policy Core Information Model (PCIM) Extensions (RFC 3460). These changes and extensions consist of new LDAP object classes and attribute types. Some of the schema items defined in this document re-implement exist...

The increase in popularity of the Internet has lead to the proliferation of heterogeneous information systems that could be better utilized if they operated under a common query interface. The purpose of this paper is to describe the representation formalism of ontologies in an LDAP-based information integration system, and to point out the advantages of such an approach over traditional system...

Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet-Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as refer...

Lightweight Directory Access Protocol (LDAP) service is a new technology being applied on the Internet. On largescale network systems using Transmission control protocol (TCP)/Internet protocol (IP), there is no standard suggested for single directory––certainly without one to be routinely used on the scale of intranets. LDAP service has many great features, such as providing quick and advanced...

In this paper, we present a CORBA directory which serves for the easy deployment of intelligent services in VHE scenarios. This approach bridges the gap between LDAP and CORBA technology as the de-facto standards for directory and distributed object technology, respectively. We have implemented both pure CORBA servers and LDAP wrappers, each of which providing fully transparent CORBA access to ...

The Globus Replica Catalog is a fundamental Data Grid service. It is important to evaluate the performance of this complex system, currently based on LDAP servers. The paper presents the results obtained during performance tests, which were done with three popular LDAP implementations (OpenLDAP, Oracle Internet Directory (OID), Netscape Directory) available today. Oracle9i is a new product and ...
