eDirectory does not use attributes to keep track of the following information about eDirectory objects:
The tree in which the object resides.
The fully distinguished name of the object.
The fully distinguished name of the context that contains the object.
The name value in the multi-valued naming attribute that is the name of the object.
Since these are not attributes, the ODBC Driver for eDirectory provides column names for this information, and these names can be used just like attribute names in SQL statements. All tables can contain the following columns:
NDS_Tree
NDS_FullName
NDS_Context
NDS_Name
