Abstract
|
||
|
||
This document defines a schema, object classes and attributes, for
|
||
printers and printer services, for use with directories that support
|
||
Lightweight Directory Access Protocol v3 (LDAP-TS). This document is
|
||
based on the printer attributes listed in Appendix E of Internet
|
||
Printing Protocol/1.1 (IPP) (RFC 2911). A few additional printer
|
||
attributes are based on definitions in the Printer MIB (RFC 1759).

RFC 3712 LDAP Schema for Printer Services February 2004
|
||
|
||
|
||
1. Introduction
|
||
|
||
This document defines several object classes to provide Lightweight
|
||
Directory Access Protocol v3 [LDAP-TS] applications with flexible
|
||
options in defining printer information using LDAP schema. Classes
|
||
are provided for defining directory entries with common printer
|
||
information as well as for extending existing directory entries with
|
||
SLPv2 [RFC2608], IPP/1.1 [RFC2911], and LPR [RFC1179] specific
|
||
information.
|
||
|
||
The schema defined in this document is based on the printer
|
||
attributes listed in Appendix E 'Generic Directory Schema' of
|
||
Internet Printing Protocol/1.1 (IPP) [RFC2911]. A few additional
|
||
printer attributes are based on definitions in the Printer MIB
|
||
[RFC1759].
|
||
|
||
The schema defined in this document is technically aligned with the
|
||
stable IANA-registered 'service:printer:' v2.0 template [SLP-PRT],
|
||
for compatibility with already deployed Service Location Protocol
|
||
(SLPv2) [RFC2608] service advertising and discovery infrastructure.
|
||
The attribute syntaxes are technically aligned with the
|
||
'service:printer:' v2.0 template - therefore simpler types are
|
||
sometimes used (for example, 'DirectoryString' [RFC2252] rather than
|
||
'labeledURI' [RFC2079] for the 'printer-uri' attribute).
|
||
|
||
Please send comments directly to the authors at the addresses listed
|
||
in Section 13 "Authors' Addresses".
|
||
|
||
1.1. Rationale for using DirectoryString Syntax
|
||
|
||
The attribute syntax 'DirectoryString' (UTF-8 [RFC2279]) defined in
|
||
[RFC2252] is specified for several groups of string attributes that
|
||
are defined in this document:
|
||
|
||
1) URI
|
||
- printer-uri, printer-xri-supported, printer-more-info
|
||
|
||
The UTF-8 encoding is forward compatible with any future
|
||
deployment of (UTF-8 based) IRI (Internationalized Resource
|
||
Identifiers) [W3C-IRI] currently being developed by the W3C
|
||
Internationalization Working Group.
|
||
|
||
2) Description
|
||
- printer-name, printer-location, printer-info,
|
||
printer-make-and-model
|
||
|
||
|
||
|
||
|
||
|
||
|
||
Fleming & McDonald Informational [Page 3]
|
||
|
||
RFC 3712 LDAP Schema for Printer Services February 2004
|
||
|
||
|
||
The UTF-8 encoding supports descriptions in any language,
|
||
conformant with the "IETF Policy on Character Sets and Languages"
|
||
[RFC2277].
|
||
|
||
Note: The printer-natural-language-configured attribute contains
|
||
a language tag [RFC3066] for these description attributes (for
|
||
example, to support text-to-speech conversions).
|
||
|
||
3) Keyword
|
||
- printer-compression-supported, printer-finishings-supported,
|
||
printer-media-supported, printer-media-local-supported,
|
||
printer-print-quality-supported
|
||
|
||
The UTF-8 encoding is compatible with the current IPP/1.1
|
||
[RFC2911] definition of the equivalent attributes, most of which
|
||
have the IPP/1.1 union syntax 'keyword or name'. The keyword
|
||
attributes defined in this document are extensible by
|
||
site-specific or vendor-specific 'names' which behave like new
|
||
'keywords'
|
||
|
||
Note: In IPP/1.1, each value is strongly typed over-the-wire as
|
||
either 'keyword' or 'name'. This union selector is not preserved
|
||
in the definitions of these equivalent LDAP attributes.
|
||
|
||
1.2. Rationale for using caseIgnoreMatch
|
||
|
||
The EQUALITY matching rule 'caseIgnoreMatch' defined in [RFC2252] is
|
||
specified for several groups of string attributes that are defined in
|
||
this document:
|
||
|
||
1) URI
|
||
|
||
These URI attributes specify EQUALITY matching with
|
||
'caseIgnoreMatch' (rather than with 'caseExactMatch') in order to
|
||
conform to the spirit of [RFC2396], which requires case
|
||
insensitive matching on the host part of a URI versus case
|
||
sensitive matching on the remainder of a URI.
|
||
|
||
These URI attributes follow existing practice of supporting case
|
||
insensitive equality matching for host names in the
|
||
associatedDomain attribute defined in [RFC1274].
|
||
|
||
Either equality matching rule choice would be a compromise:
|
||
a) case sensitive whole URI matching may lead to false negative
|
||
matches and has been shown to be fragile (given deployed client
|
||
applications that 'pretty up' host names displayed and
|
||
transferred in URI);
|
||
|
||
|
||
|
||
|
||
Fleming & McDonald Informational [Page 4]
|
||
|
||
RFC 3712 LDAP Schema for Printer Services February 2004
|
||
|
||
|
||
b) case insensitive whole URI matching may lead to false positive
|
||
matches, although it is a dangerous practice to publish URI that
|
||
differ only by case (for example, in the path elements).
|
||
|
||
2) Description
|
||
|
||
Case insensitive equality matching is more user-friendly for
|
||
description attributes.
|
||
|
||
3) Keyword
|
||
|
||
Case insensitive equality matching is more user-friendly for
|
||
keyword attributes.
|
||
|
||
1.3. Rationale for using caseIgnoreSubstringsMatch
|
||
|
||
The SUBSTR matching rule 'caseIgnoreSubstringsMatch' defined in
|
||
[RFC2252] is specified for several groups of string attributes that
|
||
are defined in this document:
|
||
|
||
1) URI
|
||
|
||
These URI attributes follow existing practice of supporting case
|
||
insensitive equality matching for host names in the
|
||
associatedDomain attribute defined in [RFC1274].
|
||
|
||
2) Description
|
||
|
||
Support for case insensitive substring matching is more
|
||
user-friendly for description attributes.
|
||
|
||
3) Keyword
|
||
|
||
Support for case insensitive substring matching is more
|
||
user-friendly for keyword attributes.
|
||
|
||
2. Terminology and Conventions
|
||
|
||
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].
|
||
|
||
Schema definitions are provided using LDAPv3 [LDAP-TS] description
|
||
formats. Definitions provided here are formatted (line wrapped) for
|
||
readability.

RFC 3712 LDAP Schema for Printer Services February 2004
|
||
|
||
|
||
3. Definition of Object Classes
|
||
|
||
We define the following LDAP object classes for use with both generic
|
||
printer related information and services specific to SLPv2 [RFC2608],
|
||
IPP/1.1 [RFC2911], and LPR [RFC1179].
|
||
|
||
slpServicePrinter - auxiliary class for SLP registered printers
|
||
printerAbstract - abstract class for all printer classes
|
||
printerService - structural class for printers
|
||
printerServiceAuxClass - auxiliary class for printers
|
||
printerIPP - auxiliary class for IPP printers
|
||
printerLPR - auxiliary class for LPR printers
|
||
|
||
The following are some examples of how applications may choose to use
|
||
these classes when creating directory entries:
|
||
|
||
1) Use printerService for directory entries containing common
|
||
printer information.
|
||
|
||
2) Use both printerService and slpServicePrinter for directory
|
||
entries containing common printer information for SLP registered
|
||
printers.
|
||
|
||
3) Use printerService, printerLPR and printerIPP for directory
|
||
entries containing common printer information for printers that
|
||
support both LPR and IPP.
|
||
|
||
4) Use printerServiceAuxClass and object classes not defined by this
|
||
document for directory entries containing common printer
|
||
information. In this example, printerServiceAuxClass is used for
|
||
extending other structural classes defining printer information
|
||
with common printer information defined in this document.
|
||
|
||
Refer to Section 4 for definition of attribute types referenced by
|
||
these object classes. We use attribute names instead of OIDs in
|
||
object class definitions for clarity. Some attribute names described
|
||
in [RFC2911] have been prefixed with 'printer-' as recommended in
|
||
[RFC2926] and [SLP-PRT].

RFC 3712 LDAP Schema for Printer Services February 2004
|

|
||
|
||
This auxiliary class defines Service Location Protocol (SLPv2)
|
||
[RFC2608] specific information. It should be used with a structural
|
||
class such as printerService. It may be used to create new or extend
|
||
existing directory entries with SLP 'service:printer' abstract
|
||
service type information as defined in [SLP-PRT]. This object class
|
||
is derived from 'slpService', the parent class for all SLP services,
|
||
defined in [RFC2926].

This abstract class defines printer information. It is a base class
|
||
for deriving other printer related classes, such as, but not limited
|
||
to, classes defined in this document. It defines a common set of
|
||
printer attributes that are not specific to any one type of service,
|

below).
|
||
|
||
The following attribute types reference matching rule names (instead
|
||
of OIDs) for clarity (see Section 6 below). For optional attributes,
|
||
if the printer information is not known, the attribute value should
|
||
not be set. In the following definitions, referenced matching rules
|
||
are defined in Section 8 of [RFC2252] and/or Section 2 of [RFC3698]
|
||
(see Section 6 'Definition of Matching Rules' below).
|
||
|
||
The following table is a summary of the attribute names defined by
|
||
this document and their corresponding names from [RFC2911]. Some
|
||
attribute names described in [RFC2911] have been prefixed with
|
||
'printer-' as recommended in [RFC2926], to address the flat namespace
|
||
for LDAP identifiers.

If the printer-xri-supported LDAP attribute is implemented, then this

Values of URI should conform to [RFC2396], although URI schemes may

be defined which do not conform to [RFC2396] (see [RFC2717] and

[RFC2718]).
|

Note: LDAP application clients should not attempt to use malformed

Note: For SLP registered printers, the LDAP printer-uri attribute

URI values read from this attribute. LDAP administrative clients

should not write malformed URI values into this attribute.
|
||
|
||
Note: This attribute is based on 'printer-uri-supported', 'uri-
|
||
authentication-supported', and `'uri-security-supported' (called the
|
||
'Three Musketeers' because they are parallel ordered attributes)
|
||
defined in IPP/1.1 [RFC2911]. This attribute unfolds those IPP/1.1
|
||
attributes and thus avoids the ordering (and same number of values)
|
||
constraints of the IPP/1.1 separate attributes.
|
||
|
||
Defined keywords for fields include:
|
||
|
||
'uri' (IPP 'printer-uri-supported')
|
||
'auth' (IPP 'uri-authentication-supported')
|
||
'sec' (IPP 'uri-security-supported')
|
||
|
||
A missing 'auth' field should be interpreted to mean 'none'. Per
|
||
IPP/1.1 [RFC2911], defined values of the 'auth' field include:
|
||
|
||
'none' (no authentication for this URI)
|
||
'requesting-user-name' (from operation request)
|
||
'basic' (HTTP/1.1 Basic [RFC2617])
|
||
'digest' (HTTP/1.1 Basic, [RFC2617])
|
||
'certificate' (from certificate)
|
||
|
||
A missing 'sec' field should be interpreted to mean 'none'. Per
|
||
IPP/1.1 [RFC2911], defined values of the 'sec' field include:
|
||
|
||
'none' (no security for this URI)
|
||
'ssl3' (Netscape SSL3)
|
||
'tls' (IETF TLS/1.0, [RFC2246])
|
||
|
||
Each XRI field should be delimited by '<'. For example:
|
||
|
||
'uri=ipp://foo.com< auth=digest< sec=tls<'
|
||
'uri=lpr://bar.com< auth=none< sec=none<'
|
||
'uri=mailto:printer@foobar.com< auth=none< sec=none<'
|
||
|
||
Note: The syntax and delimiter for this attribute are aligned with
|
||
the equivalent attribute in the 'service:printer:' v2.0 template
|
||
[SLP-PRT]. Whitespace is permitted after (but not before) the
|
||
delimiter '<'. Note that this delimiter differs from printer-
|
||
resolution-supported.
|
||
|
||
Note: See Sections 1.1, 1.2, and 1.3 for rationale for design
|
||
choices.

8. Internationalization Considerations
|
||
|
||
All text string attributes defined in this document of syntax
|
||
[RFC2279], as required by [RFC2252].
|
||
|
||
A language tag [RFC3066] for all of the text string attributes
|
||
defined in this document is contained in the printer-natural-
|
||
language-configured attribute.
|
||
|
||
|
||

Fleming & McDonald Informational [Page 28]
|
||
|
||
RFC 3712 LDAP Schema for Printer Services February 2004
|
||
|
||
|
||
Therefore, all object classes defined in this document conform to the
|
||
"IETF Policy on Character Sets and Languages" [RFC2277].
|
||
|
||
9. Security Considerations
|
||
|
||
See [RFC2829] for detailed guidance on authentication methods for
|
||
LDAP. See [RFC2830] for detailed guidance of using TLS/1.0 [RFC2246]
|
||
to supply connection confidentiality and data integrity for LDAP
|
||
sessions.
|
||
|
||
As with any LDAP schema, it is important to protect specific entries
|
||
and attributes with the appropriate access control. It is
|
||
particularly important that only administrators can modify entries
|
||
defined in this LDAP printer schema. Otherwise, an LDAP client might
|
||
be fooled into diverting print service requests from the original
|
||
printer (or spooler) to a malicious intruder's host system, thus
|
||
exposing the information in printed documents.
|
||
|
||
For additional security considerations of deploying printers in an
|
||
IPP environment, see Section 8 of [RFC2911].
