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.
web2ldap is a full-featured Web-based LDAPv3 client written in Python. It is designed to run either as with stand-alone built-in Web server or under the control of another Web server with FastCGI support (e.g. Apache with mod_fastcgi). It has support for various LDAPv3 bind methods and a powerful built-in schema browser. HTML templates are supported for displaying and editing entries, and LDIF templates can be used for quickly adding new entries. A built-in X.509 parser displays a detailed view of certificates and CRLs with active links.
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.
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.
MDS (Mandriva Directory Server), along with the Mandriva Management Console (MMC), is a powerful system that allows developers, system administrators, and other software vendors to manage users, groups, and their associated policies in both OpenLDAP server and Fedora Directory Server which allows multi-master replication. Its highly ergonomic interface design makes it very easy to use, and delegation of administration enables medium size organization to adopt MDS.
