This Vagrant configuration shows how to use the the meta-ldap server to combine two or more ldap servers
(some of which could be WindowADs) into a single setup.

It creates an environment with the following servers:

- ldap1: an Openldap server using olc configuration, dc=backend1,dc=example
- ldap2: an Openldap server using olc configuration, dc=backend2,dc=example
- ldapmeta: a meta-ldap implementation of Openldap, to proxy both ldap1 and ldap2
- ldapclient: a basic Linux server configured to use ldapmeta as its OpenLDAP server, to demonstrate how you
    login using accounts proxied by ldapmeta

The architecture is illustrated below

ldap1 --\
         >---ldapmeta---ldapclient
ldap2---/

To install the environment, run the following:
vagrant up 

To verify that ldapclient can access both accounts on the 2 proxied OpenLDAP servers, run 
$ sh test.sh

This should display both b1user1 and b2user1 UIDs, indicating that ldapclient is retrieving content
from both OpenLDAP servers (ldap1 and ldap2)


== Connecting to a WindowsAD Server

The /etc/openldap/slapd-frontend.conf contains an entry for connecting to a Windows AD server. You
need to update this entry to reflect your current WindowsAD (domain, readonly account and password
for non-anonymous access) for it to work correctly. For license reasons there is no WindowsAD server 
provided as part of this Vagrant setup.

Most of the scripts used in this setup are based on other contributions available on the internet. The time and effort spent on ensuring a complete setup was part of a project at the European Spallation Source - ERIC.
