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.
Since LDIF files are just plain text files, you can also open and edit one with Notepad++. Below is an example of what one looks like when opened in a text editor. The purpose for this particular LDIF file is to add a phone number to the entry that corresponds with this user. Tip: ZyTrax is a good resource that explains what these and other LDAP abbreviations mean.
