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.
Typically, an LDAP integration is also part of a single sign-on implementation. The integration uses the LDAP service account credentials to retrieve the user distinguished name (DN) from the LDAP server. Given the DN value for the user, the integration then rebinds with LDAP with the user's DN and password. The password that the user enters is contained entirely in the HTTPS session. The integration never stores LDAP passwords. The integration uses a read-only connection that never writes to the LDAP directory.
