python-ldap provides an object-oriented API to access LDAP directory servers from Python programs. Mainly, it wraps the OpenLDAP 2.3+ libs for that purpose. Additionally, the package contains modules for other LDAP-related stuff (such as processing LDIF, LDAPURLs, and LDAPv3 schema).
Simple Groupware is a complete enterprise application offering email, calendaring, contacts, tasks, document management, synchronization with cell phones and Outlook, full-text search, and much more. Simple Groupware combines standards like RSS, iCalendar, vCard, IMAP, POP3, SMTP, CIFS, CSV, WebDAV, LDAP, and SyncML under one platform. Unlike other groupware software, Simple Groupware contains the programming language sgsML to enable the quick customization and creation of powerful Web applications.
dFlex is a meta-directory application: a set of applications to be used for LDAP directory replication and directory data mapping and translation. It is designed as a simple and flexible framework to provide heterogenous directory data synchronization. It was originally written for a specific directory environment, and preconfigured for common tasks of replication in that environment. However, it can be easily configured to match replication, synchronization, and data mapping needs of a wide variety of directory systems and configurations.
389 Directory Server (formerly Fedora Directory Server) is a full-featured LDAPv3 compliant server. In addition to the standard LDAPv3 operations, it supports multi-master replication, fully online configuration and administration, chaining, virtual attributes, access control directives in the data, Virtual List View, server-side sorting, SASL, TLS/SSL, and many other features. The transactional Berkeley DB 4.2 is used as its data store and a full plug-in API allows developers to extend the the functionality of the server in many ways, and many of the core features of the server are already implemented using this API. The server is very mature, having started out as Netscape Directory Server.
mod-vhost-ldap is an Apache 2.x module for storing and configuring virtual hosts from LDAP. It supports DocumentRoot, ScriptAlias, ServerName, ServerAlias, ServerAdmin, and SuexecUserGroup directives. It's built on top of mod_ldap, so it uses its caching capabilities and can be used with a threaded Apache httpd.
Kolab is a groupware system that provides a comprehensive and flexible solution for workgroups. Email, contacts, and group calendars can be managed via the Web, Windows/Outlook, and Linux/KDE. It supports offline synchronization and full seamless support of mixed client environments because the Kolab-XML storage format is fully open and avoids MAPI/TNEF.
ldapuseradd is a set of utilities that aid in the management and deployment of user accounts with support for plugins to manage requirements. The LDAP user management toolset uses a highly configurable user group profile system to distinguish targeted services. It is like an LDAP-based useradd/mod/del drop-in replacement with modular features. It scales well from small businesses to ISPs, hosting providers, and universities.
Zentyal (formerly eBox Platform) is a small business server that offers small and medium businesses an affordable and easy-to-use enterprise-level computer network. It can act as a Gateway, Infrastructure Manager, Unified Threat Manager, Office Server, Unified Communication Server, or a combination of these.
ldp (LDAP Distributed Profile) will read a user-specific shell profile (.profile) from an LDAP directory server upon login, allowing users (including multiple people operating as root) to always have the same settings irrespective of which machine they are working on. ldp also operates correctly when logging in via SSH via public key auth.
Bandit is a system of loosely-coupled components that provide consistent identity services and create a community that organizes and standardizes identity-related technologies in an open way, promoting both interoperability and collaboration. It implements open standard protocols and specifications so identity services can be constructed, accessed, and integrated from multiple identity sources. The Bandit system supports many authentication methods and provides user-centric credential management.
