- Naming Guidelines for the AARNet X.500 Directory Service
-
- Status of this Memo
-
- This memo provides information for the Internet community. This memo
- does not specify an Internet standard of any kind. Distribution of
- this memo is unlimited.
-
- Background
-
- This document is an AARNet (Australian Academic and Research Network)
- Engineering Note (AEN-001). AARNet Engineering Notes are engineering
- documents of the AARNet Engineering Working Group, and record current
- or proposed operational practices related to the provision of
- Internetworking services within Australia, and AARNet in particular.
-
- Abstract
-
- AARNet is a member network of the global Internet and participates in
- the global Internet X.500 based Directory Service. A number of RFC's
- have been issued that make recommendations that alter or supplement
- the OSI/ETU standards for X.500 [1]. In general, these RFCs will be
- followed by the AARNet Directory Service. However, in certain cases
- we wish to align ourselves with our national ISO body (Standards
- Australia) rather than the Internet where they conflict. In naming,
- we have chosen to align ourselves with Standards Australia and this
- document notes the difference in our approach to the Internet
- guidelines suggested in RFC 1384 [2].
-
- 1. Introduction
-
- The intended audience of this document is the administrators (or
- potential administrators) of an X.500 Directory System Agent (DSA).
- It is assumed that the reader is familiar with the relevant Internet
- documents, especially RFC 1384.

-
- 2. The Australian X.500 domain
-
- Standards Australia (SAA) have produced a document [3] that describes
- the organisation of the Australian X.500 namespace. It is considered
- that, as far as possible, we should align the AARNet Directory
- Service with these requirements in order to provide a smooth
- transition to an Australian Directory Service as ultimately the OSI
- Registration Authority of Standards Australia has naming authority
- for the DIT subtree underneath the node "c=AU".
-
- The SAA document defines only two types of objects that can be placed
- directly below the c=AU node in the DIT, organisations with
- nationally recognised names and localities representing the states
- and territories of the Commonwealth of Australia.
-
- It is intended to follow this scheme with one modification. The
- recommendation doesn't indicate where ADMD and PRMD names should be
- registered and so these objects will be treated as for organisations
- with nationally recognised names.
-
- 3. Entries representing DSAs
-
- The naming convention currently used by the Internet leads to a large
- amount of clutter due to organisational DSAs being named directly
- under the country node. The "normal" user of a directory service
- isn't interested in the mechanics of the service and so the presence
- of these entries in such a prominent location is unfortunate. In
- order to avoid this clutter, and to conform to SAA requirements, we
- have created a pseudo organisation called DMD where all Australian
- DSAs should be registered.
-
- Rather than continue the Quipu tradition of naming DSAs after
- endangered South American animals, in Australia, it is suggested that
- DSAs be named after Australian fauna.
-
- 4. Entries representing the states and territories of Australia
-
- Immediately subordinate to the Australian entry are locality objects
- representing the eight states and territories of the Commonwealth of
- Australia. The RDN of these entries will use the stateOrProvinceName
- attribute and have values consisting of the standard Australian two
- or three letter abbreviations for the particular state of territory.
-
- 5. Entries representing organisations
-
- SAA recommends that organisations are registered as immediate
- subordinates of either the Australian entry or of the eight states
- and territories depending on the uniqueness of the organisation's

- name.
-
- Organisations that can demonstrate that they have a name unique
- within Australia (for example, if it has been allocated a name by an
- organisation that can guarantee this uniqueness such as the
- Australian Securities Commission) may be added immediately beneath
- the Australian entry. If the name is only unique within a specific
- state or territory, then the entry must be added immediately beneath
- the state entry.
-
- The names chosen for the distinguished name of an organisation must
- be the officially registered name of the organisation and have a
- maximum length of 64 characters, but other more familiar names can be
- added as additional organisation names to aid searching.
-
- 6. Entries representing residential people
-
- An individual may be registered in the directory and their entry will
- be placed subordinate to the entry for their state of residence. The
- RDN of such an entry will be composed of a combination of their
- common name and their street address.
