Used both in LDAP Schema 1 and compatibility mode for LDAP Schema 2 (with a DC Tree). This attribute is a fully qualified domain name. For an explanation of native and compatibility mode LDAP structures, see the Sun Java^TM Enterprise System Installation Guide.

In Schema 1 or compatibility mode, if more than one DC node in a DC tree refers to the same organization node in the Organization tree, this attribute is used to specify the canonical domain name used by the mail processes to open users’ mailboxes. (There can be only one canonical domain name per organization node, but there can be many DC nodes referring to the same organization node)

This attribute is not necessary if there is only one DC node referring to an organization node. If the attribute is missing, the DC node entry is taken for the canonical domain name.

If this attribute is missing and there are multiple DC nodes referring to the same organization node, the mail processes could possibly use the wrong domain name when trying to open users’ mailboxes.

Using multiple domain nodes to point to the same organization node allows you to have different attribute settings (and therefore different routing) for each one. If you want to be sure the two domains have the same attribute settings (are routed identically), use aliasedObjectName on the duplicate node instead.

This attribute is not used for the LDAP Schema 2 native mode LDAP data model.
