Used for LDAP Schema 2 only. Required to be present at the root of a subtree representing a namespace. Access Manager enforces the uniqueness attribute for namespaces.

Any organization or its subtree nodes can be designated as a namespace by extending the organization LDAP entry with this object class. Namespaces based on different unique attributes may overlap. That is, a subtree of a node designated as a namespace could also be its own namespace if the unique attributes are different. For example, the parent node could use uid to enforce uniqueness, while the child node uses the employee number.

This is a different paradigm than was used in LDAP Schema 1, in which every domain was considered a unique namespace (using uid as the default unique attribute). For LDAP Schema 2, all namespaces must be explicitly declared using this object class.

After Access Manager is installed, the root-suffix node contains this object class, but not its corresponding attribute. If you want to provision more than one unique namespace for your Messaging Server or Calendar Server installation, do not add sunNameSpaceUniqueAttrs to the root-suffix node.
