An LDAP URL Format
T. Howes, Mark Caleb Smith · RFC · 1996
LDAP is the Lightweight Directory Access Protocol, defined in [1] and [2]. This document describes a format for an LDAP Uniform Resource Locator which will allow Internet clients to have direct access to the LDAP protocol. While LDAP currently is used only as a front end to the X.500 directory, the URL format described here is general enough to handle the case of stand-alone LDAP servers (i.e., LDAP servers not back-ended by X.500).
