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.
If you have OS X and access to an LDAP server, you can enter your LDAP account into System Preferences--Internet Accounts. At bottom of the right pane, click Add Other Account, then choose the LDAP account option. This lets Address Book look up info from your server.DAP is used to look up encryption certificates, pointers to printers and other services on a network, and provide single signon where one password for a user is shared between many services. LDAP is appropriate for any kind of directory-like information, where fast lookups and less-frequent updates are the norm.
