In a UNIX file system, the top level is the root. Beneath the root you have numerous files and directories. As mentioned above, LDAP directories are set up in much the same manner.

Underneath your directory's base, you'll want to create containers that logically separate your data. For historical (X.500) reasons, most LDAP directories set these logical separations up as OU entries. OU stands for "Organizational Unit," which in X.500 was used to indicate the functional organization within a company: sales, finance, et cetera. Current LDAP implementations have kept the ou= naming convention, but break things apart by broad categories like ou=people, ou=groups, ou=devices, ... and so on. Lower level OUs are sometimes used to break categories down further. For example, an LDAP directory tree (not including individual entries) might look like this:

dc=idevelopment, dc=info ou=customers ou=asia ou=europe ou=usa ou=employees ou=rooms ou=groups ou=assets-mgmt ou=nisgroups ou=recipes
