RFC 7612
Lightweight Directory Access Protocol (LDAP): Schema for Printer Services
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] and discussed in Section 6 ("Definition of Matching Rules") later in this document. Note: For compatibility with existing implementations of [RFC3712] and underlying string length limits in [RFC2707], [RFC2911], [RFC3805], [PWG5107.2], [PWG5100.13], and [PWG5100.14], implementations of the attributes defined in this document SHOULD NOT exceed those underlying string length limits (to avoid truncation and false matches). Note: For interoperability and consistent text display, values of attributes defined in this document (a) SHOULD be normalized as recommended in "Unicode Format for Network Interchange" [RFC5198]; (b) SHOULD NOT contain DEL or any C0 or C1 control characters except for HT, CR, and LF; (c) SHOULD only contain CR and LF characters together (not as singletons); and (d) SHOULD NOT contain HT, CR, or LF characters in names, e.g., printer-name and printer-aliases. Note: Some of the following attributes are described as 'List of xxx' (using a comma as the member delimiter). Some other attributes are described as 'One of xxx' (single-valued). In all cases, any attribute can have multiple values represented as multiple instances, except where explicitly restricted in syntax to be single-valued. Note: Values of the string attributes printer-xri-supported and printer-resolution-supported use different field delimiters ('<' and '>', respectively). These two field delimiters are different for compatibility with the corresponding attributes in the IANA- registered SLP 'service:printer:' v2.0 template [SLPPRT20], which was defined before the original LDAP Printer Schema [RFC3712] was written.
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 [PWG5100.13]. 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 MUST be listed in printer-xri-supported. See [STD66] for details of URI syntax. Note: For compatibility with IPP/1.1 [RFC2911], values of this attribute SHOULD NOT exceed 1023 octets in length. 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 "Internet Printing Protocol/1.1: IPP URL Scheme" [RFC3510] and "Internet Printing Protocol (IPP) over HTTPS Transport Binding and the 'ipps' URI Scheme" [RFC7472] for conforming URI for IPP Printers. 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 1.4.1, 1.4.2, and 1.4.3 for rationale for design choices.4.2. printer-xri-supported

Each XRI field MUST be delimited by '<', with optional trailing whitespace. For example: 'uri=ipp://example.com/ipp< auth=digest< sec=tls<' 'uri=ipps://example.com/ipp< auth=digest< sec=tls<' 'uri=lpr://example.com/lpr< auth=none< sec=none<' 'uri=mailto:printer@example.com< auth=none< sec=none<' Note: See the note in Section 4 about the different field delimiters used in the printer-xri-supported and printer-resolution-supported attributes ('<' and '>', respectively), chosen for compatibility with the IANA-registered SLP 'service:printer:' v2.0 template [SLPPRT20]. Note: Multiple values for this attribute are represented as multiple instances of this attribute. See [STD66] for details of URI syntax. Note: For compatibility with IPP/1.1 [RFC2911], values of this attribute SHOULD NOT exceed 1023 octets in length.
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 the IPP/1.1 [RFC2911] attributes 'printer-uri-supported', 'uri-authentication-supported', and 'uri-security-supported' (called the 'Three Musketeers' because they are parallel, ordered attributes). 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], "IPP Job and Printer Extensions - Set 3 (JPS3)" [PWG5100.13], and the IANA IPP registry [IANAIPP], 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] and [RFC7235]) 'digest' (HTTP/1.1 Digest [RFC2617] and [RFC7235]) 'certificate' (X.509 Certificate [RFC5280] and [RFC6818]) 'negotiate' (HTTP/1.1 Negotiate [RFC4559]) The 'certificate' value refers to the IPP Client certificate extracted from the TLS session. A missing 'sec' field SHOULD be interpreted to mean 'none'. Per IPP/1.1 [RFC2911] and the IANA IPP registry [IANAIPP], defined values of the 'sec' field include: 'none' (no security for this URI) 'ssl3' (Netscape's Secure Socket Layer protocol (SSL3)) 'tls' (IETF TLS, [RFC5246]) 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: See "Internet Printing Protocol/1.1: IPP URL Scheme" [RFC3510] and "Internet Printing Protocol (IPP) over HTTPS Transport Binding and the 'ipps' URI Scheme" [RFC7472] for conforming URI for IPP Printers.

Note: For compatibility with IPP/1.1 [RFC2911], values of this attribute SHOULD NOT exceed 255 octets in length. Note: This name can be the last part of the Printer's URI, or it can be completely unrelated. This name can contain characters that are not allowed in a conventional URI (see [STD66]). Note: For interoperability, values of this attribute (a) SHOULD be normalized as recommended in "Unicode Format for Network Interchange" [RFC5198]; and (b) SHOULD NOT contain DEL or any C0 or C1 control characters.
