michael@0: -------------
michael@0: IP technology providing fast directory read access.    +-------------------+
michael@0: Part of most (if not all) Unix and Linux distros.      | ISO Model   LDAP  |
michael@0: Good integration in Blackberry, Android, and IPhone.   |   Transport TCP   |
michael@0: Standardized by the IETF in RFC 4510 and many others.  +-------------------+
michael@0: 
michael@0: Typical use cases
michael@0: -----------------
michael@0: 1) Telephone directory.
michael@0: 2) Corporate address book.
michael@0: 3) Employee ID card directory.
michael@0: 4) Password directory.

michael@0: Comparing LDAP with SQL
michael@0: -----------------------
michael@0: LPAP is a protocol, SQL is a language.
michael@0: Tuned for reading, tuned for balanced use.
michael@0: SQL provides transactions, consistency, LDAP doesn't.

michael@0: LDAP and SQL round trip comparison (UML sequence diagrams)
michael@0: ----------------------------------------------------------
michael@0: LDAP client binds to a LDAP server and stores the connection.
michael@0: client uses the LDAP connection to send queries to the server.
michael@0: The server searches a LDAP directory for the specified attributes.
michael@0: The server replies with the matched attributes along with values.

michael@0: LDAP Mainstream acceptance
michael@0: --------------------------
michael@0: Most are enterprise use cases
michael@0: 1) Suse makes widespred use of LDAP
michael@0: 2) MS Active Directory based on LDAP
michael@0: 3) Apple ease of use LDAP in Addressbook
michael@0: 4) Email address autocompletion
michael@0:      Kontact, Evolution, Thunderbird, iMail, Outlook
michael@0: 5) IP hardphones and softphones (Nokia is missing)
