"What does sendmail 8.10 have in common with Microsoft Outlook employee directories and the Yahoo interface on your cell phone? They all use - or at least can use - LDAP to access the huge directories of information they need."

"LDAP is the IETF's pragmatic reaction to the much more comprehensive X.500 directory standard established in 1988 by the International Telecommunications Union. X.500 already specifies a Directory Access Protocol, but real-world engineers in the early 1990s wanted a way to communicate with X.500 directories without consuming bandwidth... and without having to support complex data structures. LDAP works by sending requests directly on top of TCP, rather than adding extra layers for session state and data presentation into each packet. LDAP also uses plain text strings in place of complex data objects. Not only do these low-tech approaches save bandwidth, they make LDAP simpler for less technical administrators and users to learn and work with."

"LDAP has become so successful and ubiquitous as a means of accessing information that sendmail 8.10 has incorporated LDAP support to let administrators replace standalone configuration files with a central directory service."
