What is OpenLDAP?

What is OpenLDAP?

A central user management running on LDAP or Active Directory is standard these days. The server software OpenLDAP integrates the IETF standard LDAP (Lightweight Directory Access Protocol) and serves as a reference system for other implementations based on this protocol. There are many commercial LDAP servers; however, with OpenLDAP there is an open source option available which is free and has some additional advantages:

With OpenLDAP

  • you use one of the most powerful LDAP implementations.
  • you benefit from the enormous flexibility that allows the application to adapt to the performance of your hardware.
  • your IT infrastructure gains vital stability.

OpenLDAP is a collaborative project aiming to create a fully-featured open source LDAP suite providing applications and development tools. The project is administrated by a global community of developers. The Internet serves as a planning and developing platform as well as a medium to communicate the respective documentation.

Learn more about the project on the official OpenLDAP website.

Directory Management

Directory Management with OpenLDAP

Directory services like OpenLDAP act as containers for directories (databases) that can store various information. Such directory servers can be used if

  1. a hierarchically structured data storage is requested, and if
  2. these data should high-performantly be retrievable via the network .

The entries consist of attributes that are specified by object classes as mandatory or optional attributes. Very often, OpenLDAP is used as an exceptionally scalable (with hundreds of millions of entries) and highly performant (with 10,000 accesses per second and more) authentication server; but also any other form of data can be stored. Moreover, any customer-specific extension can be programmed via an overlay mechanism (a plugin interface).

Symas OpenLDAP

Symas OpenLDAP

Besides the OpenLDAP packages from Linux distributions or self compiled installations, Symas OpenLDAP is the most stable version of OpenLDAP distributions that are currently available.

Behind Symas OpenLDAP is Symas Corporation, a US-American partner of DAASI International, whose employees are among others the main developers of OpenLDAP. The company is specialized on open-source based solutions for IAM infrastructures. Symas Corporation is the company with the most comprehensive OpenLDAP knowledge.

The product comes as a pre-compiled package for different Linux distributions and offers – depending on the version „Silver“ or „Gold“ – several compiled modules as well as support. Distributions that will no longer include OpenLDAP in future releases are also supported.

Symas relies on proven open source software for the OpenLDAP distribution, as for example OpenSSL, Cyrus SASL, Heimdal Kerberos or Berkeley DB, but offers at the same time with the database LMDB (Lightning Memory-Mapped Database) or the Hash method PBKDF2 contemporary technologies for better performance and higher security.

The advantages of Symas OpenLDAP:

  • high performance and high availability
  • up to date with the latest security patches
  • includes many enhancements before they are available in general release
  • third-level support by the developers at Symas (24×7 support available in the „Gold“ version)
  • direct packaging by the main developers
  • independence of Linux distributions
