Introduction This document defines several object classes to provide Lightweight Directory Access Protocol [RFC4510] 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] protocol-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], IEEE-ISTO PWG Command Set for IEEE 1284 Device ID (PWG 5107.2), or IEEE-ISTO PWG IPP Job and Printer Extensions - Set 3 (IPP JPS3). The schema defined in this document is technically aligned with the stable IANA-registered 'service:printer:' v2.0 template [SLPPRT20], 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' [RFC4517] rather than 'labeledURI' [RFC2079] for the 'printer-uri' attribute). Please send comments directly to the authors at the addresses listed in the section "Authors' Addresses". 1.1. Rationale for using DirectoryString Syntax The attribute syntax 'DirectoryString' (UTF-8 [STD63]) defined in [RFC4517] 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 compatible with deployment of (UTF-8 based) IRI Internationalized Resource Identifiers (IRIs) [RFC3987]. 2) Description - printer-name, printer-location, printer-info, printer-make-and-model The UTF-8 encoding supports descriptions in any language, Fleming, McDonald Expires 2 April 2012 [Page 5] Internet Draft LDAP Schema for Printer Services 2 October 2011 conformant with the IETF Policy on Character Sets and Languages [BCP18]. Note: The printer-natural-language-configured attribute contains a language tag [BCP47] 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 [RFC4517] 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 [STD66], 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 [RFC4524]. 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); 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). Fleming, McDonald Expires 2 April 2012 [Page 6] Internet Draft LDAP Schema for Printer Services 2 October 2011 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 [RFC4517] 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 [RFC4524]. 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 [RFC2119]. Schema definitions are provided using LDAP [RFC4510] description formats. Definitions provided here are formatted (line wrapped) for readability. Fleming, McDonald Expires 2 April 2012 [Page 7] Internet Draft LDAP Schema for Printer Services 2 October 2011 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 [SLPPRT20]. Fleming, McDonald Expires 2 April 2012 [Page 8] Internet Draft LDAP Schema for Printer Services 2 October 2011 3.1. slpServicePrinter ( 1.3.18.0.2.6.254 NAME 'slpServicePrinter' DESC 'Service Location Protocol (SLP) information.' AUXILIARY SUP slpService ) 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 [SLPPRT20]. This object class is derived from 'slpService', the parent class for all SLP services, defined in [RFC2926]. 3.2. printerAbstract ( 1.3.18.0.2.6.258 NAME 'printerAbstract' DESC 'Printer related information.' ABSTRACT SUP top MAY ( printer-name $ printer-natural-language-configured $ printer-location $ printer-info $ printer-more-info $ printer-make-and-model $ printer-multiple-document-jobs-supported $ printer-charset-configured $ printer-charset-supported $ printer-generated-natural-language-supported $ printer-document-format-supported $ printer-color-supported $ printer-compression-supported $ printer-pages-per-minute $ printer-pages-per-minute-color $ printer-finishings-supported $ printer-number-up-supported $ printer-sides-supported $ printer-media-supported $ printer-media-local-supported $ printer-resolution-supported $ printer-print-quality-supported $ printer-job-priority-supported $ printer-copies-supported $ printer-job-k-octets-supported $ printer-current-operator $ printer-service-person $ printer-delivery-orientation-supported $ printer-stacking-order-supported $ printer-output-features-supported $ printer-device-id $ printer-charge-info-uri $ Fleming, McDonald Expires 2 April 2012 [Page 9] Internet Draft LDAP Schema for Printer Services 2 October 2011 printer-geo-location $ printer-organization $ printer-organizational-unit $ printer-uuid ) ) 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, protocol or operating system. 3.3. printerService ( 1.3.18.0.2.6.255 NAME 'printerService' DESC 'Printer information.' STRUCTURAL SUP printerAbstract MAY ( printer-uri $ printer-xri-supported ) ) This structural class defines printer information. It is derived from class printerAbstract and thus inherits common printer attributes. This class can be used with or without auxiliary classes to define printer information. Auxiliary classes can be used to extend the common printer information with protocol, service or operating system specific information. Note: When extending other structural classes with auxiliary classes, printerService should not be used. 3.4. printerServiceAuxClass ( 1.3.18.0.2.6.257 NAME 'printerServiceAuxClass' DESC 'Printer information.' AUXILIARY SUP printerAbstract MAY ( printer-uri $ printer-xri-supported ) ) This auxiliary class defines printer information. It is derived from class printerAbstract and thus inherits common printer attributes. This class should be used with a structural class. Fleming, McDonald Expires 2 April 2012 [Page 10] Internet Draft LDAP Schema for Printer Services 2 October 2011 3.5. printerIPP ( 1.3.18.0.2.6.256 NAME 'printerIPP' DESC 'Internet Printing Protocol (IPP) information.' AUXILIARY SUP top MAY ( printer-ipp-versions-supported $ printer-ipp-extensions-supported $ printer-multiple-document-jobs-supported ) ) This auxiliary class defines Internet Printing Protocol (IPP/1.1) [RFC2911] information. It should be used with a structural class such as printerService. It is used to extend structural classes with IPP specific printer information. 3.6. printerLPR ( 1.3.18.0.2.6.253 NAME 'printerLPR' DESC 'LPR information.' AUXILIARY SUP top MUST ( printer-name ) MAY ( printer-aliases) ) This auxiliary class defines LPR [RFC1179] information. It should be used with a structural class such as printerService. It is used to identify directory entries that support LPR. Fleming, McDonald Expires 2 April 2012 [Page 11] Internet Draft LDAP Schema for Printer Services 2 October 2011 4. Definition of Attribute Types The following attribute types are referenced by the object classes defined in Section 3. The following attribute types reference syntax OIDs defined in Section 3 of [RFC4517] (see Section 5 'Definition of Syntaxes' 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 4 of [RFC4517] (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 source document names as defined in [RFC2911], [RFC3805], [PWG5107.2], or [IPPJPS3]. Some source attribute names have been prefixed with 'printer-' as recommended in [RFC2926], to address the flat namespace for LDAP identifiers.

EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE ) If the printer-xri-supported LDAP attribute is implemented, then this printer-uri value should be listed in printer-xri-supported. Values of URI should conform to [STD66], although URI schemes may be defined which do not conform to [STD66] (see [BCP35]). Note: LDAP application clients should not attempt to use malformed URI values read from this attribute. LDAP administrative clients should not write malformed URI values into this attribute. Note: For SLP registered printers, the LDAP printer-uri attribute should be set to the value of the SLP-registered URL of the printer, for interworking with SLPv2 [RFC2608] service discovery. Note: See Sections 1.1, 1.2, and 1.3 for rationale for design choices. 4.2. printer-xri-supported ( 1.3.18.0.2.4.1107 NAME 'printer-xri-supported' DESC 'The unordered list of XRI (extended resource identifiers) supported by this printer.' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 ) A list of XRI (extended resource identifiers) supported by this printer. Each value of this list should consist of a URI (uniform resource identifier) followed by (optional) authentication and security fields. Values of URI should conform to [STD66], although URI schemes may be defined which do not conform to [STD66] (see [BCP35]). Fleming, McDonald Expires 2 April 2012 [Page 14] Internet Draft LDAP Schema for Printer Services 2 October 2011 Note: LDAP application clients should not attempt to use malformed 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, [RFC5246]) 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 [SLPPRT20]. 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. Fleming, McDonald Expires 2 April 2012 [Page 15] Internet Draft LDAP Schema for Printer Services 2 October 2011 4.3. printer-name ( 1.3.18.0.2.4.1135 NAME 'printer-name' DESC 'The site-specific administrative name of this printer.' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{127} SINGLE-VALUE ) Values of this attribute should be specified in the language specified in printer-natural-language-configured (for example, to support text-to-speech conversions), although the printer's name may be specified in any language. This name may be the last part of the printer's URI or it may be completely unrelated. This name may contain characters that are not allowed in a conventional URI (see [STD66]). 4.4. printer-natural-language-configured ( 1.3.18.0.2.4.1119 NAME 'printer-natural-language-configured' DESC 'The configured natural language in which error and status messages will be generated (by default) by this printer.' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{127} SINGLE-VALUE ) Also, a possible natural language for printer string attributes set by operator, system administrator, or manufacturer. Also, the (declared) natural language of the printer-name, printer-location, printer-info, and printer-make-and-model attributes of this printer. Values of language tags should conform to Tags for Identifying Languages [BCP47]. For example: 'en-us' (English as spoken in the US) 'fr-fr' (French as spoken in France) Note: For consistency with IPP/1.1 [RFC2911], language tags in this attribute should be lowercase normalized. Fleming, McDonald Expires 2 April 2012 [Page 16] Internet Draft LDAP Schema for Printer Services 2 October 2011 4.5. printer-location ( 1.3.18.0.2.4.1136 NAME 'printer-location' DESC 'The physical location of this printer.' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{127} SINGLE-VALUE ) For example: 'Room 123A' 'Second floor of building XYZ' 4.6. printer-info ( 1.3.18.0.2.4.1139 NAME 'printer-info' DESC 'Descriptive information about this printer.' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{127} SINGLE-VALUE ) For example: 'This printer can be used for printing color transparencies for HR presentations' 'Out of courtesy for others, please print only small (1-5 page) jobs at this printer' 'This printer is going away on July 1, 1997, please find a new printer' 4.7. printer-more-info ( 1.3.18.0.2.4.1134 NAME 'printer-more-info' DESC 'A URI for more information about this specific printer.' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE Fleming, McDonald Expires 2 April 2012 [Page 17] Internet Draft LDAP Schema for Printer Services 2 October 2011 ) For example, this could be an HTTP type URI referencing an HTML page accessible to a Web Browser. The information obtained from this URI is intended for end user consumption. Values of URI should conform to [STD66], although URI schemes may be defined which do not conform to [STD66] (see [BCP35]). Note: LDAP application clients should not attempt to use malformed URI values read from this attribute. LDAP administrative clients should not write malformed URI values into this attribute. Note: See Sections 1.1, 1.2, and 1.3 for rationale for design choices. 4.8. printer-make-and-model ( 1.3.18.0.2.4.1138 NAME 'printer-make-and-model' DESC 'Make and model of this printer.' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{127} SINGLE-VALUE ) Note: The printer manufacturer may initially populate this attribute. 4.9. printer-ipp-versions-supported ( 1.3.18.0.2.4.1133 NAME 'printer-ipp-versions-supported' DESC 'IPP protocol version(s) that this printer supports.' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{127} ) The IPP protocol version(s) should include major and minor versions, i.e., the exact version numbers for which this Printer implementation meets the IPP version-specific conformance requirements. Fleming, McDonald Expires 2 April 2012 [Page 18] Internet Draft LDAP Schema for Printer Services 2 October 2011 4.10. printer-multiple-document-jobs-supported ( 1.3.18.0.2.4.1132 NAME 'printer-multiple-document-jobs-supported' DESC 'Indicates whether or not this printer supports more than one document per job.' EQUALITY booleanMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.7 SINGLE-VALUE ) 4.11. printer-charset-configured ( 1.3.18.0.2.4.1109 NAME 'printer-charset-configured' DESC 'The configured charset in which error and status messages will be generated (by default) by this printer.' EQUALITY caseIgnoreMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15{63} SINGLE-VALUE ) Also, a possible charset for printer string attributes set by operator, system administrator, or manufacturer.

Internationalization Considerations All text string attributes defined in this document of syntax 'DirectoryString' [RFC4517] have values that are encoded in UTF-8 [STD63], as required by [RFC4517]. A language tag [BCP47] for all of the text string attributes defined in this document is contained in the printer-natural-language-configured attribute. Therefore, all object classes defined in this document conform to the IETF Policy on Character Sets and Languages [BCP18]. 9. Security Considerations See [RFC4513] for detailed guidance on authentication methods for LDAP and the use of TLS/1.2 [RFC5246] 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].
