Novell eDirectory (formerly called Novell Directory Services) is an X.500 compatible directory service software product released in 1993 by Novell, Inc. for centrally managing access to resources on multiple servers and computers within a given network. It is used in over 80% of Fortune 1000 companies and competes with Microsoft's Active Directory, Sun's Java System Directory Server and Red Hat's Fedora Directory Server.
eDirectory is a hierarchical, object oriented database that represents all the assets in an organisation in a logical tree. Assets can include people, positions, servers, workstations, applications, printers, services, groups, etc. The use of dynamic rights inheritance and equivalence allows both global and fine grained access controls to be implemented efficiently. Access rights between objects in the tree are determined at the time of the request and is determined by the rights assigned to the objects by virtue of their location in the tree, any security equivalences and individual assignments.
eDirectory supports partitioning at any point in the tree and replication of that partition to any number of servers. Replication between each server occurs periodically using deltas of the objects to reduce LAN/WAN traffic. Each server can act as a master of the information it holds (providing the replica is not read only). Additionally, replicas may be filtered to only include defined attributes to increase speed (eg a replica may be configured to only include a users name and phone number for use in a corporate address book).
Referential integrity, multi-master replication and the modular authentication architecture are other major advantages.
eDirectory can be accessed via LDAP, XML, Directory Service Markup Language, SOAP, ODBC, JDBC, JNDI, EJB, Perl, Active X and ADSI and has been proven to scale to over 1 billion objects.

[edit] Storage
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 OS. Since version 8, eDirectory, along with the GroupWise collaboration suite starting with version 5, uses the FLAIM database engine originally used by the now-defunct WordPerfect Office. This change allowed for it to be ported to other platforms such as Windows, Linux and Unix.

- As of mid 2006, eDirectory was still powering CNN's website, as noted at the bottom of the page. [1][2]
