Local Directory unit is a set of files containing unit data (records/entries), unit schema, unit settings, and unit modification journal.
Open the Directory WebAdmin page and click the name of a Local Storage Unit. The unit Settings page opens.
Log: Use this setting to specify what kind of information the Local Storage Unit Manager should put in the Server Log.
Enforce Schema: When this option is selected, the Local Storage Unit Manager compares the structure of all new and updated records with the Unit Schema. If this option is disabled, then the Manager checks only the names of the record attributes and ensures that those attributes are included into the Unit Schema, but it does not enforce the objectClass-related restrictions.
Search Results Limit: This setting limits the maximum number of records a Directory Search operation can return.
Compose 'displayName' attribute: If this option is selected, the Local Storage Unit Manager checks if the displayName attribute is explicitly requested in a search operation, but this attribute is absent in a retrieved Directory record. In this case, the Manager composes the displayName attribute on-the-fly, using the cn attribute, or, if it is absent, the uid attribute.
Each Local Unit has its own Schema. See the Schema section for more details on Unit Schemas.
You can browse and modify the Local Unit Schema by retrieving and modifying the virtual record with the cn=schema DN. If the Local Unit is mounted on some Directory subtree, the DN for the Unit Schema record is cn=schema,subtree.
