Michael Ströder's web2ldap provides browser-based access to an LDAP server.
Once installed, web2ldap is simple to use. Make sure you have an LDAP URL in etc/web2ldap/web2ldapcnf/hosts.py, that points to OpenDS such as http://localhost:389 or http://localhost:1389, and start web2ldap.

As web2ldap can also discover the schema, you can use it to add and modify entries.
