The Basics: An Introduction to Directory Services, LDAP, and X.500
A section of An LDAP Roadmap & FAQ: A tutorial aid to navigating
various LDAP and X.500 resources on the Internet, v2.0a
by: Jeff Hodges
This is v2.0a -- a "beta" release -- it is still way under construction. You will find version 1.5, which may or may not be more up-to-date, HERE. Apologies for any confusion.
Start here if you're just beginning...
These are basic introductory documents to directory services in general,
in particular. I've arranged them to be read nominally in this order --
but of course that's entirely up to you. There's a fair amount of overlap
in these overview docs, by the way....
The Lightweight Directory Access Protocol: X.500 Lite, Timothy
A. Howes, July 27, 1995, CITI Technical Report 95-8
Howes95 gives a good overview of the X.500 model, and then
describes the LDAP model and rationale in detail.
Understanding X.500 - The Directory, David Chadwick, University
of Salvord, UK. International Thomson Computer Press edition 1996 ISBN
185 0332 813.
This book is an excellent text on X.500. Next best thing is to read
the X.500 documents themselves (see this page
for pointers to them).
Vendor-specific Directory information resources
The papers below have salient introductory information about directory
services, though they are quite vendor-specific...
The PC Webopaedia is a good
starting point to learn about many aspects of Internet technologies and
to find definitions of and further resources for technical terms. It is
a product of Sandy Bay Software
and is advertiser-supported.
Executive Introduction to Directory Services Using the X.500 Protocol.
C. Weider, J. Reynolds. March 1992. (Format: TXT=9392 bytes) (Status: INFORMATIONAL,
RFC1308 gives a good, concise overview of the X.500 model. Note
that LDAP is based closely upon the X.500 model.
Technical Overview of Directory Services Using the X.500 Protocol.
C. Weider, J. Reynolds, S. Heker. March 1992. (Format: TXT=35694 bytes)
(Status: INFORMATIONAL, FYI 14)
RFC1309 builds upon the one above to provide a more detailed technical
introduction to how X.500-based directory services work.
Introduction to White Pages Services based on X.500. P. Jurg.
August 1994. (Format: TXT=22985 bytes) (Status: INFORMATIONAL)
RFC1684 provides an overview of both X.500 basics, plus how X.500-based
Directory services globally work in a broad sense.
The next section of these
Roadmap pages provides pointers to the LDAP protocol specifications, associated
standards documents, as well as other resources.
