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 hierarchical 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.

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.
