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.
An LDAP directory can be distributed among many servers. LDIF is used to synchronize each LDAP directory. The first step in synchronizing LDAP directories is extracting the full contents of or a portion of the original LDAP directory and formatting the contents into an LDIF file. The LDIF file is then mailed to a directory synchronization robot called DIRBOT. After several different steps, a final LDIF file is compared to the original LDIF file. The update instructions on what records to add, delete, or modify in the original directory are decided.
