This site, sponsored by Stanford University's Computing and Communications Group, is maintained by Jeff Hodges, Project Manager of Stanford's Enterprise Directory Services Project. It is an annotated metasite designed as a tutorial and aid to navigating resources on the Internet relating to the directory services protocols LDAP (the Lightweight Directory Services Protocol) and X.500. The site houses a number of resources relating to LDAP version 3, which was recently advanced to proposed Internet standard status. The roadmap is organized into sections such as introductory articles and presentations on directory service, information on advanced topics such as schema and directory organization, a bibliography of directory services, standards and requests for comments (RFC), and pointers to available implementations.
