The X.500 Directory uses distinguished names as the primary keys to entries in the directory. Distinguished Names are encoded in ASN.1 in the X.500 Directory protocols. In the Lightweight Directory Access Protocol, a string representation of distinguished names is transferred. This specification defines the string format for representing names, which is designed to give a clean representation of commonly used distinguished names, while being able to represent any distinguished name.

This document describes a directory access protocol that provides

both read and update access. Update access requires secure

authentication, but this document does not mandate implementation of

any satisfactory authentication mechanisms.

In accordance with RFC 2026, section 4.4.1, this specification is

being approved by IESG as a Proposed Standard despite this

limitation, for the following reasons:

a. to encourage implementation and interoperability testing of

these protocols (with or without update access) before they

are deployed, and

b. to encourage deployment and use of these protocols in read-only

applications. (e.g. applications where LDAPv3 is used as

a query language for directories which are updated by some

secure mechanism other than LDAP), and

c. to avoid delaying the advancement and deployment of other Internet

standards-track protocols which require the ability to query, but

not update, LDAPv3 directory servers.

Readers are hereby warned that until mandatory authentication

mechanisms are standardized, clients and servers written according to

this specification which make use of update functionality are



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.
