Appendix D: Standards

This section provides an overview of the most frequently used object classes and attribute types. The notation is the one used in the RFCs and in the OpenLDAP schema definitions. Different server implementations use other syntaxes for the definition of the schema elements; you will find more about different syntaxes in Chapter 3. For more in-depth information about object classes, attribute type definitions, and syntaxes, you can use the LDAP Schema Viewer available at http://ldap.akbkhome.com. The site's excellent design (maintained by Alan Knowles) makes it an invaluable tool for anyone needing to better understand the schema elements of LDAP.
