OpenLdap ldap proxy

Another usefull feature of openLDAP is ldap backend.With it you can use a ldap server as a backend for queries. This backend is very similar to the "meta" backend, but you must use the same DN in both origin and target servers.

In example

############  LDAP opensso users ##################################
database ldap
suffix          "ou=persons,dc=test,dc=es"
uri             ldap://localhost:1389/

Will be shown in the proxy ldap as base DN: ou=persons,dc=test,dc=es

If you want to map the base DN with diferent names then meta-backend is your friend

Openldap script backend

Openldap allows you to customize the backend in several ways. The most usefull in order to prepare a prototype is shellbackend.
With this backend you can create a custom shellscript or executable and use it to return a ldap response.
