Directory Access Protocol (DAP)

The Directory Access Protocol (DAP) is used by Directory User Agemts (DUAs) to retrieve information from a Directory System Agent (DSA). The information in the DSA is stored in entries in a hierachical form, with each entry containing attributes that are specific to one of more object classes. DAP allows a client to list, search, add, delete, modify and rename the entries within the DSA.

If a DSA does not hold the information being searched for, it may chain the DAP operation to another DSA using ["DSP"].


Protocol dependencies

Example traffic

XXX - Add example traffic here (as plain text or Ethereal screenshot).


The PROTO dissector is (fully functional, partially functional, not existing, ... whatever the current state is). Also add info of additional Ethereal features where appropriate, like special statistics of this protocol.

Preference Settings

There is a single preference field for the DAP dissector, the DAP TCP Port - the port to which DAP associations are made. The default value is 102.

Example capture file

To be provided.

Display Filter

A complete list of DAP display filter fields can be found in the [ display filter reference]

Capture Filter

You cannot directly filter DAP protocols while capturing. However, if you know the ["TCP"] port used (see above), you can filter on that one.
