Active Directory (AD) is a directory service developed by Microsoft for Windows domain networks. Windows Server operating systems include it as a set of processes and services. Originally, only centralized domain management used Active Directory. However, it ultimately became an umbrella title for various directory-based identity-related services.
The Lightweight Directory Access Protocol is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. Directory services play an important role in developing intranet and Internet applications by allowing the sharing of information about users, systems, networks, services, and applications throughout the network. As examples, directory services may provide any organized set of records, often with a hierarchical structure, such as a corporate email directory. Similarly, a telephone directory is a list of subscribers with an address and a phone number.
OSGi is an open specification and open source project under the Eclipse Foundation.
Mac OS X Server is a series of discontinued Unix-like server operating systems developed by Apple Inc. based on macOS. It provided server functionality and system administration tools, and tools to manage both macOS-based computers and iOS-based devices, network services such as a mail transfer agent, AFP and SMB servers, an LDAP server, and a domain name server, as well as server applications including a Web server, database, and calendar server.
Apache Tomcat is a free and open-source implementation of the Jakarta Servlet, Jakarta Expression Language, and WebSocket technologies. It provides a "pure Java" HTTP web server environment in which Java code can also run. Thus it is a Java web application server, although not a full JEE application server.
OpenLDAP is a free, open-source implementation of the Lightweight Directory Access Protocol (LDAP) developed by the OpenLDAP Project. It is released under its own BSD-style license called the OpenLDAP Public License.
In computing, a directory service or name service maps the names of network resources to their respective network addresses. It is a shared information infrastructure for locating, managing, administering and organizing everyday items and network resources, which can include volumes, folders, files, printers, users, groups, devices, telephone numbers and other objects. A directory service is a critical component of a network operating system. A directory server or name server is a server which provides such a service. Each resource on the network is considered an object by the directory server. Information about a particular resource is stored as a collection of attributes associated with that resource or object.
The Distributed Computing Environment (DCE) is a software system developed in the early 1990s from the work of the Open Software Foundation (OSF), a consortium founded in 1988 that included Apollo Computer, IBM, Digital Equipment Corporation, and others. The DCE supplies a framework and a toolkit for developing client/server applications. The framework includes:
The Central Authentication Service (CAS) is a single sign-on protocol for the web. Its purpose is to permit a user to access multiple applications while providing their credentials only once. It also allows web applications to authenticate users without gaining access to a user's security credentials, such as a password. The name CAS also refers to a software package that implements this protocol.
WebSphere Application Server Community Edition (WASCE) was a free-of-charge, certified Java EE 6 application server for building and managing Java applications. Until September 30, 2016, it was IBM's supported distribution of Apache Geronimo that usee Tomcat for servlet container and Axis 2 for web services. Another difference from Apache Geronimo is that WASCE came with Db2 and Informix database drivers, better XML parser libraries and contained the latest patches from unreleased upstream versions. Over 30 WASCE developers were committers in the Apache Geronimo project.
Apple Open Directory is the LDAP directory service model implementation from Apple Inc. A directory service is software which stores and organizes information about a computer network's users and network resources and which allows network administrators to manage users' access to the resources.
The Sun Java System Directory Server is a discontinued LDAP directory server and DSML server written in C and originally developed by Sun Microsystems. The Java System Directory Server is a component of the Java Enterprise System. Earlier iterations of Sun Java System Directory Server were known as Sun ONE Directory Server, iPlanet Directory Server, and, before that, Netscape Directory Server.
Apache Felix is an open source implementation of the OSGi Core Release 6 framework specification. The initial codebase was donated from the Oscar project at ObjectWeb. The developers worked on Felix for a full year and have made various improvements while retaining the original footprint and performance. On June 21, 2007, the project graduated from incubation as a top level project and is considered the smallest size software at Apache Software Foundation.
Thrift is an interface definition language and binary communication protocol used for defining and creating services for programming languages. It was developed by Facebook. Since 2020, it is an open source project in the Apache Software Foundation.
Apache Fortress is an open source project of the Apache Software Foundation and a subproject of the Apache Directory. It is an authorization system, written in Java, that provides role-based access control, delegated administration and password policy using an LDAP backend.
Apache LDAP API is an open source project of the Apache Software Foundation and a subproject of the Apache Directory. It's a replacement for outdated Java/LDAP libraries like and works with any LDAP server.
Log4Shell (CVE-2021-44228) is a zero-day vulnerability in Log4j, a popular Java logging framework, involving arbitrary code execution. The vulnerability had existed unnoticed since 2013 and was privately disclosed to the Apache Software Foundation, of which Log4j is a project, by Chen Zhaojun of Alibaba Cloud's security team on 24 November 2021. Before an official CVE identifier was made available on 10 December 2021, the vulnerability circulated with the name "Log4Shell", given by Free Wortley of the LunaSec team, which was initially used to track the issue online. Apache gave Log4Shell a CVSS severity rating of 10, the highest available score. The exploit was simple to execute and is estimated to have had the potential to affect hundreds of millions of devices.
