Overview#LDAP Descriptor is the "NAME" or "Short Names" of the LDAP Schema elements.
LDAP Descriptor are shown as Attribute-Names
LDAP allows descriptive names (or descriptors) to be used instead of a numeric Object Identifier to identify select protocol extensions RFC 4511, schema elements RFC 4512, LDAP URL RFC 4516 extensions, and other objects.
LDAP Descriptor are defined in RFC 4512 as more readable aliases for Object Identifiers (OIDs) and are used to identify various LDAP Schema elements. However, it is not expected that LDAP implementations with human user interface would display these short names (or the object identifiers they refer to) to the user.
Instead, they would most likely be performing translations (such as expressing the short name in one of the local national languages).
For example, the short name "st" (stateOrProvinceName) might be displayed to a German-speaking user as "Land".
The same short name might have different meaning in different subschemas, and, within a particular subschema, the same short name might refer to different object identifiers each identifying a different kind of schema element.
Implementations MUST be prepared that the same short name might be used in a subschema to refer to the different kinds of schema elements. That is, there might be an object class 'x-fubar' and an attribute type 'x-fubar' in a subschema.
Implementations MUST be prepared that the same short name might be used in the different subschemas to refer to the different schema elements. That is, there might be two matching rules 'x-fubar', each in different subschemas.
