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"].

A complete list of DAP display filter fields can be found in the [http://www.wireshark.org/docs/dfref/d/dap.html 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.
