The ou=people subtree is split across three servers, according to the first letter of the sn attribute for each entry. The naming context (dc=example,dc=com) and the ou=groups containers are stored in one database on each server. This database is accessible to entries under ou=people. The ou=people container is stored in its own database.
The following illustration shows how the data is stored on the individual Directory Servers.
Note that the ou=people container is not a subsuffix of the top container.
