eDirectory is an X.500-compatible directory service software product from NetIQ. Previously owned by Novell, the product has also been known as Novell Directory Services (NDS) and sometimes referred to as NetWare Directory Services. NDS was initially released by Novell in 1993 for Netware 4, replacing the Netware bindery mechanism used in previous versions, for centrally managing access to resources on multiple servers and computers within a given network. eDirectory is a hierarchical, object oriented database used to represent certain assets in an organization in a logical tree, including organizations, organizational units, people, positions, servers, volumes, workstations, applications, printers, services, and groups to name just a few.
eDirectory uses dynamic rights inheritance, which allows both global and specific access controls. Access rights to objects in the tree are determined at the time of the request and are determined by the rights assigned to the objects by virtue of their location in the tree, any security equivalences, and individual assignments. The software supports partitioning at any point in the tree, as well as replication of any partition to any number of servers. Replication between servers occurs periodically using deltas of the objects. Each server can act as a master of the information it holds (provided the replica is not read only). Additionally, replicas may be filtered to only include defined attributes to increase speed (for example, a replica may be configured to only include a name and phone number for use in a corporate address book, as opposed to the entire directory user profile).
The software supports referential integrity, multi-master replication, and has a modular authentication architecture. It can be accessed via LDAP, DSML, SOAP, ODBC, JDBC, JNDI, and ADSI.
When Novell first designed their directory, they decided to store large amounts of their operational server data within the directory in addition to just user account information. As a result, a typical Novell directory contains a large pool of additional objects representing the servers themselves and any software services running on those servers, such as LDAP or email software.
Versions of eDirectory prior to version 8 (then called Novell Directory Services) used a record-based database management engine called Recman, which relied on the Transaction Tracking System built into the NetWare operating system. Since version 8, eDirectory (along with the GroupWise collaboration suite, starting with version 5) uses the FLAIM (FLexible Adaptable Information Management) database engine. FLAIM is an open source embeddable database engine developed by Novell and released under the GPL license in 2006. This change allowed for it to be ported to other platforms such as Windows, Linux, and Unix.
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.
Novell, Inc. was an American software and services company headquartered in Provo, Utah, that existed from 1980 until 2014. Its most significant product was the multi-platform network operating system known as Novell NetWare.
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.
NetWare is a discontinued computer network operating system developed by Novell, Inc. It initially used cooperative multitasking to run various services on a personal computer, using the IPX network protocol.
Banyan VINES is a discontinued network operating system developed by Banyan Systems for computers running AT&T's UNIX System V.
IPX/SPX stands for Internetwork Packet Exchange/Sequenced Packet Exchange. IPX and SPX are networking protocols used initially on networks using the Novell NetWare operating systems. They also became widely used on networks deploying Microsoft Windows LANS, as they replaced NetWare LANS, but are no longer widely used. IPX/SPX was also widely used prior to and up to Windows XP, which supported the protocols, while later Windows versions do not, and TCP/IP took over for networking.
Btrieve is a transactional database software product. It is based on Indexed Sequential Access Method (ISAM), which is a way of storing data for fast retrieval. There have been several versions of the product for DOS, Linux, older versions of Microsoft Windows, 32-bit IBM OS/2 and for Novell NetWare.
M+NetMail was an ISP-grade E-mail package by Messaging Architects. It was designed to deliver scalable messaging and calendaring services, using Internet-standard protocols, across a large enterprise, or to a large group of users who are not particularly associated. The original name for the product, when owned by Novell, was Novell Internet Messaging System (NIMS). Messaging Architects showcased NetMail on its MyRealBox website, this service was discontinued on June 1, 2011.
Mercury Mail Transport System is a standards-compliant mail server developed by David Harris, who also develops the Pegasus Mail client.
Open Enterprise Server (OES) is a server operating system published by OpenText. It was first published by Novell in March 2005 to succeed their NetWare product.
The NetWare Core Protocol (NCP) is a network protocol used in some products from Novell, Inc. It is usually associated with the client-server operating system Novell NetWare which originally supported primarily MS-DOS client stations, but later support for other platforms such as Microsoft Windows, the classic Mac OS, Linux, Windows NT, Mac OS X, and various flavors of Unix was added.
IBM Storage Protect is a data protection platform that gives enterprises a single point of control and administration for backup and recovery. It is the flagship product in the IBM Spectrum Protect family.
A NetWare Loadable Module (NLM) is a loadable kernel module that can be loaded into Novell's NetWare operating system. NLMs can implement hardware drivers, server functions, applications, system libraries or utilities.
Microsoft Identity Integration Server (MIIS) is an identity management (IdM) product offered by Microsoft. It is a service that aggregates identity-related information from multiple data-sources. The goal of MIIS is to provide organizations with a unified view of a user's/resources identity across the heterogeneous enterprise and provide methods to automate routine tasks.
An embedded database system is a database management system (DBMS) which is tightly integrated with an application software; it is embedded in the application. It is a broad technology category that includes:
ZENworks, a suite of software products developed and maintained by OpenText for computer systems management, aims to manage the entire life cycle of servers, of desktop PCs, of laptops, and of handheld devices such as Android and iOS mobile phones and tablets. As of 2011 Novell planned to include Full Disk Encryption (FDE) functionality within ZENworks. ZENworks supports multiple server platforms and multiple directory services.
GroupWise is a messaging and collaboration platform from OpenText that supports email, calendaring, personal information management, instant messaging, and document management. The GroupWise platform consists of desktop client software, which is available for Windows,, and the server software, which is supported on Windows Server and Linux.
Actian Zen is an ACID-compliant, Zero-DBA, Embedded, Nano-footprint, Multi-Model, Multi-Platform database management system (DBMS) developed originally by Pervasive Software, which was acquired by Actian Corporation in 2013.
A domain controller (DC) is a server that responds to security authentication requests within a computer network domain. It is a network server that is responsible for allowing host access to domain resources. It authenticates users, stores user account information and enforces security policy for a domain. It is most commonly implemented in Microsoft Windows environments, where it is the centerpiece of the Windows Active Directory service. However, non-Windows domain controllers can be established via identity management software such as Samba and Red Hat FreeIPA.
