LDAP

Lightweight Directory Access Protocol. LDAP is a client-server protocol for accessing a directory service. It was initially used as a front-end to X.500, but can also be used with stand-alone and other kinds of directory servers. LDAP is an interface to a database for cases where you are willing to have slow writes/updates in exchange for highly optimised reading/searching, e.g. telephone book lookup.

An LDAP directory entry is a collection of attributes with a name, called a distinguished name (DN). The various types of additional data obout that DN, (e.g. phone number, email address, mailing address, security access code) may have restricted access to a subset of users of the database.

You may recognise the distinguished name scheme from the one used in setting up code signing certificates.

LDAP directory entries are arranged in a hierarchical structure that reflects political, geographic, and/or organisational boundaries.
