German: DAP

DAP stands for Directory Access Protocoll

The Directory Access Protocoll was developed for communication between Directory Services of the X.500 family. DAP's complexity and the use of its own OSI protocoll stack, which was later replaced by TCP/IP, worked against a wide spread of the Protocoll, however. This led to development of the Leightweight Directory Access Protocoll (LDAP), which is based on DAP, but implements only its most commonly used functions.
