Apache Geronimo-Apache Directory Server Plugin
· This plugin integrates the Apache Directory Server (ApacheDS)
LDAP server with Geronimo. That means that Geronimo will run
an embedded LDAP server when it starts. This LDAP server may
be used for LDAP security realms within Geronimo, as well as
for other purposes by Geronimo applications or by remote
applications.
For more information on the ApacheDS project, see
