Storing Vendor Information in the LDAP root DSE

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 [RFC 2251].  The associated
   syntaxes are defined in section 4 of [RFC 2252].

   Servers MAY restrict access to vendorName or vendorVersion and
   clients MUST NOT expect these attributes to be available.

2.1 vendorName

   This attribute contains a single string, which represents the name of
   the LDAP server implementer.

   All LDAP server implementations SHOULD maintain a vendorName, which
   is generally the name of the company that wrote the LDAP Server code
   like "Novell, Inc."

        SINGLE-VALUE NO-USER-MODIFICATION USAGE dSAOperation )

2.2 vendorVersion

   This attribute contains a string which represents the version of the
   LDAP server implementation.
