4 Designing the directory tree

The directory tree provides a way to refer to the data stored by the directory service. The types of information stored in the directory, the physical nature of the enterprise, the applications used with the directory, and the types of replication implemented shape the design of the directory tree.

This chapter outlines the steps for designing the directory tree.

4.1 Introduction to the directory tree

The directory tree provides a means for the directory data to be named and referred to by client applications. The directory tree interacts closely with other design decisions, including the choices available distributing, replicating, or controlling access to the directory data. Invest time to properly design the directory tree before deployment. A properly designed directory tree can save considerable time and effort both during the deployment phase, and later when the directory service is in operation.

A well-designed directory tree provides the following:

Simplified directory data maintenance.

Flexibility in creating replication policies and access controls.

Support for the applications using the directory service.

Simplified directory navigation for directory users.

The structure of the directory tree follows the hierarchical LDAP model. A directory tree provides a way to organize the data in different logical ways, such as by group, personnel, or place. It also determines how to partition data across multiple servers. For example, each database needs data to be partitioned at the suffix level. Without the proper directory tree structure, it may not be able to spread the data across multiple servers efficiently.

In addition, replication is constrained by the type of directory tree structure used. Carefully define partitions for replication to work. To replicate only portions of the directory tree, take that into account during the design process.

To use access controls on branch points, also consider that in the directory tree design.

NOTE:

Directory Server supports a concept for hierarchical navigation and organization of directory information called virtual directory information tree views. See “Virtual directory information tree views” before designing the directory tree.

4.2 Designing the directory tree

There are several major decisions to plan in the directory tree design:

Choosing a suffix to contain the data.

Determining the hierarchical relationship among data entries.

Naming the entries in the directory tree hierarchy.

4.2.1Choosing a suffix

The suffix is the name of the entry at the root of the directory tree, and the directory data are stored beneath it. The directory can contain more than one suffix. It is possible to use multiple suffixes if there are two or more directory trees of information that do not have a natural common root.

By default, the standard Directory Server deployment contains multiple suffixes, one for storing data and the others for data needed by internal directory operations (such as configuration

HP UX Directory Server is a robust and scalable solution designed for managing directory information within enterprise networks. Developed by Hewlett-Packard (HP), this server offers an extensive set of features tailored to meet the needs of organizations that require an efficient way to store, manage, and retrieve identity and access data.

One of the key features of HP UX Directory Server is its ability to handle large directories with significant volumes of data. Built on a highly optimized architecture, it provides excellent performance and can support millions of entries without sacrificing speed or reliability. This capability makes it an ideal choice for large-scale deployments in enterprises that require high availability and responsiveness.

In addition to its scalability, HP UX Directory Server supports a wide range of protocols, including LDAP (Lightweight Directory Access Protocol), which ensures seamless integration with diverse applications and systems across various platforms. The server maintains standards compliance, which facilitates interoperability and simplifies administration tasks.

Security is a top priority for HP UX Directory Server, offering an array of features to protect sensitive information. It supports secure data transmission via TLS/SSL protocols, ensuring encrypted communication between clients and servers. Advanced access controls allow administrators to define fine-grained permissions, helping to safeguard directory data against unauthorized access.

Another salient feature of HP UX Directory Server is its replication capabilities. The server can replicate directory data across multiple instances, ensuring data consistency and availability in distributed environments. This feature is essential for businesses operating across different geographical locations or requiring failover solutions for disaster recovery.

HP UX Directory Server also comes equipped with tools for data management, including an intuitive administration console for configuring and monitoring the server. Additionally, it offers customizable schema capabilities, enabling organizations to tailor the directory structure to fit their specific needs.

Integration with existing identity management solutions is streamlined through connectors and APIs, allowing organizations to extend their directory services and enhance user experience.

In summary, HP UX Directory Server is a powerful directory management solution that combines scalability, security, and integration flexibility. Its support for industry standards, advanced replication, and comprehensive administrative tools makes it an essential asset for organizations seeking to manage identity and access efficiently. By leveraging this technology, businesses can improve their operational efficiency and ensure a secure and organized approach to directory management.
