ldap2dns is a program to read DNS (Domain Name Service) records from an LDAP directory and format them into flat files suitable for TinyDNS (or Bind). ldap2dns reduces all kinds of administration overhead: no more flat file editing, no more zone file editing. After having installed ldap2dns, the administrator only has to modify the data stored in the LDAP directory. Access control can be configured for each zone, GUIs can be more easily implemented, and all other kinds of zone and resource record information can be managed without interfering with the DNS server directly.
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).
LDAP Account Manager (LAM) is a web frontend for managing entries (e.g. users, groups, DHCP settings) stored in an LDAP directory. LAM was designed to make LDAP management as easy as possible for the user. It abstracts from the technical details of LDAP and allows persons without technical background to manage LDAP entries. If needed, power users may still directly edit LDAP entries via the integrated LDAP browser.
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.
PALDAP is yet another LDAP administration tool which includes a complete PHP LDAP API. It features an advanced LDAP schema parser. It is designed to be comfortable for experienced LDAP administrators, but it is also made so that LDAP administrators can configure it in such a way that it will be easy enough for their users to use.
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.
