LDAP Admin is a free, open-source LDAP directory management tool licensed under the GNU General Public License. Small and compact, LDAP Admin is also highly configurable through the use of the template extensions. In addition to common browsing and editing functions, LDAP Admin provides a directory management functionality by supporting a number of application-specific LDAP objects such as Posix and Samba groups and accounts, Postfix objects and a number of Active Directory objects. It also provides an XML-based template engine which extends the application in a seamless way allowing it to support virtually unlimited number of user defined objects.

Some of the key features include:

As of version 1.3 the templates support for JavaScript and VBScript was introduced providing for a dynamic templates.

LDAP Admin runs on the Windows operating systems only. By using the Wine software, it is apparently possible to run the application on a Linux and Mac OS X operating systems. There is also a Linux port of LdapAdmin.
