Overview#

Directory Information Base (DIB) is information held in an DSA
RFC 4512 clearly distinguishes the Directory Information Tree as the "Structure" or the entries and the Directory Information Base as the Information.
Often RFCs and other documents do not make any distinction and use only Directory Information Tree for both the "Structure" and the "Information"

Directory Information Tree (DIT) determines how the information is arranged.

A Directory user, which may be a human or other entity, accesses the Directory through a client (or Directory User Agent (DUA)).

The client, on behalf of the directory user, interacts with one or more servers (or Directory System Agents (DSA)).

A server holds at least a fragment of the Directory Information Base (DIB).

The Directory Information Base contains two classes of information:

  • user information (e.g., information provided and administrated by users)
  • administrative and operational information (e.g., information used to administer and/or operate the directory)

These two models, referred to as the generic Directory Information Models, describe how information is represented in the Directory.

These generic models provide a framework for other information models.
