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.
LDAP technology consists of both a network protocol and a standard architecture for organizing the directory data. As a protocol, LDAP is a simplified version of the Data Access Protocol (DAP) used in the earlier standard X.500. LDAP's chief advantage over its predecessor is the ability to run over TCP/IP. As a network architecture, LDAP utilizes a distributed tree structure similar to X.500.
