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.
