Abstract

This document specifies two Lightweight Directory Access Protocol (LDAP) attributes, vendorName and vendorVersion that MAY be included in the root DSA-specific Entry (DSE) to advertise vendor-specific information. These two attributes supplement the attributes defined in section 3.4 of RFC 2251.

Abstract

This document specifies two Lightweight Directory Access Protocol (LDAP) attributes, vendorName and vendorVersion that MAY be included in the root DSA-specific Entry (DSE) to advertise vendor-specific information. These two attributes supplement the attributes defined in section 3.4 of RFC 2251.

The information held in these attributes MAY be used for display and informational purposes and MUST NOT be used for feature advertisement or discovery.

1. Overview

LDAP clients discover server-specific data--such as available controls, extensions, etc.--by reading the root DSE. See section 3.4 of [RFC2251] for details.

For display, information, and limited function discovery, it is desirable to be able to query an LDAP server to determine the vendor name of that server and also to see what version of that vendor's code is currently installed.

RFC 3045 LDAP Root DSE to Display Vendor Information January 2001

1.1 Function discovery

There are many ways in which a particular version of a vendor's LDAP server implementation may be functionally incomplete, or may contain software anomalies. It is impossible to identify every known shortcoming of an LDAP server with the given set of server data advertisement attributes. Furthermore, often times, the anomalies of an implementation are not found until after the implementation has been distributed, deployed, and is in use.

The attributes defined in this document MAY be used by client implementations in order to identify a particular server implementation so that it can 'work around' such anomalies.

The attributes defined in this document MUST NOT be used to gather information related to supported features of an LDAP implementation. All LDAP features, mechanisms, and capabilities--if advertised--MUST be advertised through other mechanisms, preferably advertisement mechanisms defined in concert with said features, mechanisms, and capabilities.

2. Attribute Types

These attributes are an addition to the Server-specific Data Requirements defined in section 3.4 of [RFC2251]. The associated syntaxes are defined in section 4 of [RFC2252].

Servers MAY restrict access to vendorName or ve...
