RFC 2256 LDAPv3 Schema December 1997 Implementors are hereby discouraged from deploying LDAPv3 clients or servers which implement the update functionality, until a Proposed Standard for mandatory authentication in LDAPv3 has been approved and published as an RFC. 2. Abstract This document provides an overview of the attribute types and object classes defined by the ISO and ITU-T committees in the X.500 documents, in particular those intended for use by directory clients. This is the most widely used schema for LDAP/X.500 directories, and many other schema definitions for white pages objects use it as a basis. This document does not cover attributes used for the administration of X.500 directory servers, nor does it include attributes defined by other ISO/ITU-T documents. The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [6]. 3. General Issues This document references syntaxes given in section 6 of this document and section 6 of [1]. Matching rules are listed in section 8 of this document and section 8 of [1]. The attribute type and object class definitions are written using the BNF form of AttributeTypeDescription and ObjectClassDescription given in [1]. Lines have been folded for readability. 4. Source The schema definitions in this document are based on those found in X.500 [2],[3],[4],[5], and updates to these documents, specifically: Sections Source ============ ============ 5.1 - 5.2 X.501(93) 5.3 - 5.36 X.520(88) 5.37 - 5.41 X.509(93) 5.42 - 5.52 X.520(93) 5.53 - 5.54 X.509(96) 5.55 X.520(96) 6.1 RFC 1274 6.2 (new syntax) 6.3 - 6.6 RFC 1274 7.1 - 7.2 X.501(93) 7.3 - 7.18 X.521(93) Wahl Standards Track
