In computing , an organizational unit ( OU ) provides a way of classifying objects located in directories , or names in a digital certificate hierarchy , typically used either to differentiate between objects with the same name (John Doe in OU "marketing" versus John Doe in OU "customer service"), or to parcel out authority to create and manage objects (for example: to give rights for user-creation to local technicians instead of having to manage all accounts from a single central group). Organizational units most commonly appear in X.500 directories, X.509 certificates, Lightweight Directory Access Protocol (LDAP) directories, Active Directory (AD), and Lotus Notes directories and certificate trees, but they may feature in almost any modern directory or digital certificate container grouping system.

24-473: A common policy to them. Organizational Units give a hierarchical structure, and when properly designed can ease administration. Novell and Lotus supplied the two largest software directory systems. Each of these companies started with flat account and directory structures, and encountered the support and name-conflict limitations inherent in their flat structures. They adopted the X.500 OU concept into their next-generation software around 1993 – Novell with
36-403: 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
48-483: 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

In many systems one OU can also exist within another OU. When OUs are nested, as one OU contains another OU, this creates a relationship where

84-557: The contained OU is called the child and the container is called the parent. Thus, OUs are used to create a hierarchy of containers within a domain. Only OUs within the same domain can have relationships. OUs of the same name in different domains are independent. The name organizational unit appears to represent a single organization with multiple units (departments) within that organization . However, OUs do not always follow this model. They might represent geographical regions, job-functions, associations with other (external) groups, or
96-430: 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
108-519: 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,
120-524: 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
132-491: The release of Novell Directory Services (subsequently known as eDirectory), and Lotus with the release of the third version of Lotus Notes. Microsoft allegedly used Novell's directory as a blueprint for the first released versions of AD, but this claim appears suspect, given that X.500 served as the "granddaddy" of all directory systems. Novell eDirectory eDirectory is an X.500 -compatible directory service software product from NetIQ . Previously owned by Novell ,

Examples would include: In Sun Java System Directory Server and Microsoft Active Directory (AD), an organizational unit (OU) can contain any other unit, including other OUs, users, groups, and computers. Organizational units in separate domains may have identical names but are independent of each other. OUs let an administrator group computers and users so as to apply
