INTERNET-DRAFT draft-ietf-ldapbis-iana-05.txt 20 December 2001
1. Introduction
The Lightweight Directory Access Protocol [LDAPTS] (LDAP) is an
extensible protocol. LDAP supports:
- addition of new operations,
- extension of existing operations, and
- extensible schema.
This document details procedures for registering values of used to
unambiguously identify extensible elements of the protocol including:
- LDAP message types,
- LDAP result codes,
- LDAP authentication methods,
- LDAP attribute description options, and
- Object Identifier descriptors.
These registries are maintained by the Internet Assigned Numbers
Authority (IANA).
In addition, this document provides guidelines to IANA describing the
conditions under which new values can be assigned.
2. Terminology and Conventions
This section details terms and conventions used in this document.
2.1. Policy Terminology
The terms "IESG Approval", "Standards Action", "IETF Consensus",
"Specification Required", "First Come First Served", "Expert Review",
and "Private Use" are used as defined in BCP 26 [RFC2434].
2.2. Requirement Terminology
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 BCP 14 [RFC2119].
2.3. Common ABNF Productions
A number of syntaxes in this document are described using ABNF
[RFC2234]. These syntaxes rely on the following common productions:
Zeilenga IANA Considerations for LDAP [Page 2]
INTERNET-DRAFT draft-ietf-ldapbis-iana-05.txt 20 December 2001
ALPHA = %x41-5A / %x61-7A ; A-Z / a-z
LDIGIT = %x31-39 ; 1-9
DIGIT = %x30 / LDIGIT ; 0-9
HYPHEN = %x2D ; "-"
PERIOD = %x2E ; "."
number = DIGIT / ( LDIGIT 1*DIGIT )
keychar = ( ALPHA / DIGIT / HYPHEN )
leadkeychar = ALPHA
keystring = leadkeychar *keychar
A keyword is UTF-8 [RFC2279] case-insensitive string restricted to the
keystring production.
3. IANA Considerations for LDAP
This section details each kind of protocol value which can be
registered and provides IANA guidelines on how to assign new values.
3.1. Object Identifiers
Numerous LDAP schema and protocol elements are identified by Object
Identifiers. Any properly delegated OID MAY be used, including those
under "Internet Private Enterprise Numbers" (1.3.5.1.4.1.x) assigned
by IANA <http://www.iana.org/cgi-bin/enterprise.pl>.
For IETF developed protocol and schema elements, OIDs under "Internet
Directory Numbers" (1.3.6.1.1.x) MAY be used. IANA will assign
numbers under this OID arc upon Expert Review with Specification
Required. In general, only one OID per specification SHOULD be
assigned. The specification may then assign any number of OIDs within
this arc without further coordination with IANA.
3.2. Object Identifier Descriptors
LDAP allows short descriptive names (or descriptors) to be used
instead of a numeric Object Identifier to identify protocol extensions
[RFC2251], schema elements [RFC2252], LDAP URL [RFC2255] extensions,
Zeilenga IANA Considerations for LDAP [Page 3]
INTERNET-DRAFT draft-ietf-ldapbis-iana-05.txt 20 December 2001
and other objects. Descriptors SHALL be restricted to UTF-8
case-insensitive strings limited by the following ABNF:
name = keystring
Multiple names MAY be assigned to a given OID. For purposes of
registration, an OID SHALL be represented in numeric OID form
conforming to the ABNF:
numericoid = number *( PERIOD number ) ; e.g. 1.1.0.23.40
While the protocol places no maximum length restriction upon
descriptors, they SHOULD be short. Descriptors longer than 48
characters MAY be viewed as too long to register. IANA MAY reject
obviously bogus registrations.
Descriptors beginning with "x-" are for Private Use and SHALL NOT be
registered.
Descriptors beginning with "e-" are reserved for experiments. IANA
SHALL register any descriptor beginning with "e-" on a First Come
First Served basis.
Expert Review is REQUIRED before accepting registration of all other
descriptors.
IANA SHALL NOT verify the registrant "owns" the OID being named.
The OID namespace is managed by The ISO/IEC Joint Technical Committee
1 - Subcommittee 6.
3.3. AttributeDescription Options
An AttributeDescription [RFC2251, Section 4.1.5] can contain zero or
more options specifying additional semantics. An option SHALL be
restricted to UTF-8 case-insensitive string limited by the following
ABNF:
option = keystring
While the protocol places no maximum length restriction upon option
strings, they SHOULD be short. Options longer than 24 characters MAY
be viewed as too long to register. IANA MAY reject obviously bogus
registrations.
Values ending with a hyphen ("-") reserve all option names which start
with the name. For example, the registration of the option
Zeilenga IANA Considerations for LDAP [Page 4]
INTERNET-DRAFT draft-ietf-ldapbis-iana-05.txt 20 December 2001
"optionFamily-" reserves all options which start with "optionFamily-"
for some related purpose.
Options beginning with "x-" are for Private Use and SHALL NOT
registered.
Options beginning with "e-" are reserved for experiments. IANA SHALL
register any option beginning with "e-" on a First Come First Served
basis.
IANA SHALL register other options by either Standards Action or Expert
Review with Specification Required.
3.4. LDAP Message Types
Each protocol message is encapsulated in an LDAPMessage envelope
[RFC2251, Section 4.1.1]. The protocolOp CHOICE indicates the type of
message encapsulated. Each message type consists of a keyword and a
non-negative choice number is combined with the class (APPLICATION)
and data type (CONSTRUCTED or PRIMITIVE) to construct the BER tag in
the message's encoding. The choice numbers for existing protocol
messages are implicit in the protocol's ASN.1 defined in [RFC2251].
New values SHALL only be registered by Standards Track action.
Note: LDAP provides extensible messages which reduces, but does not
eliminate, the need to add new message types.
3.5. LDAP Result Codes
LDAP result messages carry an resultCode enumerated value to indicate
the outcome of the operation [RFC2251, Section 4.1.10]. Each result
code consists of a keyword and a non-negative integer.
IANA SHALL register new resultCode integers in the range 0-255 upon
Standards Action, in the range 256-1023 with Expert Review, and in the
range 1024-8191 on a First Come First Served basis. Keywords
associated with integers in the range 0-1023 SHALL NOT start with "e-"
or "x-". Keywords associated with integers in the range 1024-8191
SHALL start with "e-". Values greater than or equal to 8192 and
keywords starting with "x-" are for Private Use and SHALL NOT be
registered.
IANA MAY reject obviously bogus registrations.
Zeilenga IANA Considerations for LDAP [Page 5]
INTERNET-DRAFT draft-ietf-ldapbis-iana-05.txt 20 December 2001
3.6. LDAP Authentication Method
The LDAP Bind operation supports multiple authentication methods
[RFC2251, Section 4.2]. Each authentication choice consists of a
keyword and a non-negative integer.
Authentication methods usage SHALL be classified using one of the
following terms:
COMMON - method is appropriate for common use on the Internet,
LIMITED USE - method is appropriate for limited use,
OBSOLETE - method has been deprecated or otherwise found to be
inappropriate for any use.
IANA SHALL NOT register new OBSOLETE authentication methods. Methods
without publicly available specifications SHALL NOT be classified as
COMMON. IANA MAY reject obviously bogus registrations.
IANA SHALL register new authentication method integers in the range
0-255 upon Standards Action, in the range 256-1023 with Expert Review
with Specification Required, and in the range 1024-8191 on a First
Come First Served basis. Keywords associated with integers in the
range 0-1023 SHALL NOT start with "e-" or "x-". Keywords associated
with integers in the range 1024-8191 SHALL start with "e-". Values
greater than or equal to 8192 and keywords starting with "x-" are for
Private Use and SHALL NOT be registered.
Note: LDAP supports SASL [RFC2222] as an Authentication CHOICE. SASL
is an extensible LDAP authentication method.
3.7. Directory Systems Names
The IANA-maintained "Directory Systems Names" registry [IANADSN] of
valid keywords for well known attributes used in the LDAPv2 string
representation of a distinguished name [RFC1779]. RFC 1779 was
obsoleted by RFC 2253.
Directory systems names are not known to be used in any other context.
LDAPv3 uses Object Identifier Descriptors [Section 3.2] (which have a
different syntax than directory system names).
IANA SHALL NOT register new Directory System Names. For historical
purposes, the current list of registered names SHOULD remain
available.
4. Registration Procedure
Zeilenga IANA Considerations for LDAP [Page 6]
INTERNET-DRAFT draft-ietf-ldapbis-iana-05.txt 20 December 2001
The procedure given here MUST be used by anyone who wishes to use a
new value of a type described in Section 3 of this document.
The first step is for the requester to fill out the appropriate form.
Templates are provided in Appendix A.
If the policy is Standards Action, the completed form SHOULD be
provided to the IESG with the request for Standards Action. Upon
approval of the Standards Action, the IESG SHALL forward the request
(possibly revised) to IANA. The IESG SHALL be viewed as the owner of
all values requiring Standards Action.
If the policy is Expert Review, the requester SHALL post the completed
form to the <directory@apps.ietf.org> mailing list for public review.
The review period is two (2) weeks. If a revised form is later
submitted, the review period is restarted. Anyone may subscribe to
this list by sending a request to <directory-request@apps.ietf.org>.
During the review, objections may be raised by anyone (including the
Expert) on the list. After completion of the review, the Expert,
based upon public comments, SHALL either approve the request and
forward it to the IESG OR deny the request. In either case, the
Expert SHALL promptly notify the requester of the action . Actions of
the Expert may be appealed [RFC2026]. The Expert is appointed by
Applications Area Director(s). The requester is viewed as the owner
of values registered under Expert Review.
If the policy is First Come First Served, the requester SHALL submit
the completed form directly to the IANA <iana@iana.org>. The
requester is viewed as the owner of values registered under First Come
First Served.
Neither the Expert nor IANA will take position on the claims of
copyright or trademarks issues regarding completed forms.
5. Registration Maintenance
This section discusses maintenance of registrations.
5.1. Lists of Registered Values
IANA makes lists of registered values readily available to the
Internet community on their web site <http://www.iana.org/>.
5.2. Change Control
Zeilenga IANA Considerations for LDAP [Page 7]
INTERNET-DRAFT draft-ietf-ldapbis-iana-05.txt 20 December 2001
The registration owner MAY update the registration subject to the same
constraints and review as with new registrations. In cases where the
owner is not unable or unwilling to make necessary updates, the IESG
MAY assert ownership in order to update the registration.
5.3. Comments
For cases where others (anyone other than the owner) have significant
objections to the claims in a registration and the owner does not
agree to change the registration, comments MAY be attached to a
registration upon Expert Review. For registrations owned by the IESG,
the objections SHOULD be addressed by initiating a request for Expert
Review.
The request form to these requests is ad hoc, but MUST include the
specific objections to be reviewed and SHOULD contain (directly or by
reference) materials supporting the objections.
6. Security Considerations
The security considerations detailed in [RFC2434] are generally
applicable to this document. Additional security considerations
specific to each namespace are discussed in Section 3 where
appropriate.
Security considerations for LDAP are discussed in documents comprising
the technical specification [LDAPTS].
