In a directory tree, an organizational unit represents a major subdirectory. A directory tree usually contains more than one organizational unit. An LDIF file that defines an organizational unit entry must appear as follows:
dn: distinguished_name objectClass: top objectClass: organizationalUnit ou: organizational_unit_namelist_of_optional_attributes...
The following example shows an organizational unit entry in LDIF format:
dn: ou=people, o=example.com objectclass: top objectclass: organizationalUnit ou: people description: Fictional organizational unit for example purposes
The following table defines each element of the organizational unit entry.
