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 the client authenticates successfully to the LDAP server, then when the server subsequently receives a request from the client, it will check whether the client is allowed to perform the request. This process is called access control. In LDAP, authentication is supplied in the bind operation. Ldapv3 supports three types of authentication: anonymous, simple and SASL authentication. A client that sends a LDAP request without doing a bind is treated as an anonymous client.
