Highclere Castle, Berkshire, from Downton Abbey. The 5,000-acre estate and Jacobethan castle shot to fame due to ITV's hit series about British class. In fact, Downton could well have saved the property, owned by the Earl and Countess of Carnarvon, from closure. It needed Â£11.75 million worth of repairs prior to the series.
LDAP stands for Lightweight Directory Access Protocol. As the name suggests, it is a lightweight protocol for accessing directory services, specifically X.500-based directory services. LDAP runs over TCP/IP or other connection oriented transfer services.
Technically, LDAP is a directory access protocol to an X.500 directory service, the OSI directory service. Initially, LDAP clients accessed gateways to the X.500 directory service. This gateway ran LDAP between the client and gateway and X.500's Directory Access Protocol (DAP) between the gateway and the X.500 server.
