OpenLDAP – Open Source Directory Service

Directory services, such as OpenLDAP, offer an object-oriented database in which different kinds of information can be stored. This kind of directory server is used when

1. hierarchically structured data storage is necessary
2. data should be retrievable via the network with high performance

The entries consist of attributes which are specified as either mandatory or optional attribute via their respective object class. Using these object classes makes it possible to retroactively augment data without having to change the old client logic. This is a significant advantage vis-à-vis relational databases.

OpenLDAP can be used as highly scalable (more than hundreds of millions of entries), and highly performant (thousands of access requests per second) authentication server, nonetheless it can also be used to store all kinds of different data. Moreover, with the overlay mechanism (several plugin interfaces) further customised extensions can be programmed.

Apart from the OpenLDAP packages from Linux distributions, Symas OpenLDAP currently is the most stable version available, for which 24/7 support can also be provided.

The company behind Symas OpenLDAP is Symas Corporation, a US partner of DAASI International, whose employees include the main developers of OpenLDAP. The company specialises in open source based solutions for IAM infrastructures. Symas Corporation is the company with the most comprehensive knowledge of OpenLDAP worldwide and offers the following two product versions:

OpenLDAP for Linux

This is an openly accessible version, which replaces the standard OpenLDAP packages in popular Linux distributions, esp. for:

• RHEL 7 and 8
• SuSE Linux Enterprise Server 11,12 and 15
• Solutions for other Linux distributions upon request

This option stands out for its superior stability and performance, and is available in the form of a subscription for companies. In addition to extensive support, this also includes several additional features, i. e. password policy management, which are not included in the OpenLDAP for Linux version.

Generally, Symas relies on well-established open source software such as OpenSSL, Cyrus SASL and Heimdal Kerberos for its OpenLDAP distributions. In addition, Symas offers modern technologies for better performance and higher security with the LMDB (Lightning Memory-Mapped Database) database or the PBKDF2 hash procedure.

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
• direct packaging by the main developers (24×7 possible)
• independence of Linux distributions
