The Lightweight Directory Access Protocol (LDAP) uses X.500- compatible distinguished names [3] for providing unique identification of entries.
轻量级目录访问协议（LDAP）使用X.500兼容的可分辨名称[3]来提供条目的唯一标识。
This document defines an algorithm by which a name registered with the Internet Domain Name Service [2] can be represented as an LDAP distinguished name.
本文档定义了一种算法，通过该算法，向Internet域名服务[2]注册的名称可以表示为LDAP可分辨名称。
The Domain (Nameserver) System (DNS) provides a hierarchical resource labeling system. A name is made up of an ordered set of components, each of which are short strings. An example domain name with two components would be "CRITICAL-ANGLE.COM".
域（名称服务器）系统（DNS）提供了一个分层的资源标签系统。名称由一组有序的组件组成，每个组件都是短字符串。有两个组件的域名示例是“CRITICAL-ANGLE.COM”。
LDAP-based directories provide a more general hierarchical naming framework. A primary difference in specification of distinguished names from domain names is that each component of an distinguished name has an explicit attribute type indication.
基于LDAP的目录提供了更通用的分层命名框架。区分名称规范与域名规范的主要区别在于，区分名称的每个组件都有一个明确的属性类型指示。
X.500 does not mandate any particular naming structure. It does contain suggested naming structures which are based on geographic and national regions, however there is not currently an established registration infrastructure in many regions which would be able to assign or ensure uniqueness of names.
X.500不要求任何特定的命名结构。它确实包含基于地理区域和国家区域的建议命名结构，但是，目前许多区域还没有能够指定或确保名称唯一性的既定登记基础设施。
The mechanism described in this document automatically provides an enterprise a distinguished name for each domain name it has obtained for use in the Internet. These distinguished names may be used to identify objects in an LDAP directory.
本文档中描述的机制会自动为企业提供一个可分辨名称，该名称是企业获得的用于Internet的每个域名的专有名称。这些可分辨名称可用于标识LDAP目录中的对象。
An example distinguished name represented in the LDAP string format [3] is "DC=CRITICAL-ANGLE,DC=COM". As with a domain name, the most significant component, closest to the root of the namespace, is written last.
LDAP字符串格式[3]中表示的示例可分辨名称是“DC=CRITICAL-ANGLE，DC=COM”。与域名一样，最重要的组件（最接近名称空间的根）最后写入。
This document does not define how to represent objects which do not have domain names. Nor does this document define the procedure to locate an enterprise's LDAP directory server, given their domain name. Such procedures may be defined in future RFCs.
本文档不定义如何表示没有域名的对象。本文档也没有定义查找给定域名的企业LDAP目录服务器的过程。此类程序可在未来的RFC中定义。
This section defines a subset of the possible distinguished name structures for use in representing names allocated in the Internet Domain Name System. It is possible to algorithmically transform any Internet domain name into a distinguished name, and to convert these distinguished names back into the original domain names.
本节定义了可分辨名称结构的子集，用于表示在Internet域名系统中分配的名称。可以通过算法将任何互联网域名转换为可分辨名称，并将这些可分辨名称转换回原始域名。
The algorithm for transforming a domain name is to begin with an empty distinguished name (DN) and then attach Relative Distinguished Names (RDNs) for each component of the domain, most significant (e.g. rightmost) first. Each of these RDNs is a single AttributeTypeAndValue, where the type is the attribute "DC" and the value is an IA5 string containing the domain name component.
转换域名的算法是以空的可分辨名称（DN）开始，然后为域的每个组件附加相对可分辨名称（RDN），首先是最重要的（例如最右边的）。这些RDN中的每一个都是单个AttributeTypeAndValue，其中类型是属性“DC”，值是包含域名组件的IA5字符串。
Thus the domain name "CS.UCL.AC.UK" can be transformed into
因此，域名“CS.UCL.AC.UK”可以转换为
DC=CS,DC=UCL,DC=AC,DC=UK
DC=CS,DC=UCL,DC=AC,DC=UK
Distinguished names in which there are one or more RDNs, all containing only the attribute type DC, can be mapped back into domain names. Note that this document does not define a domain name equivalence for any other distinguished names.
存在一个或多个RDN的可分辨名称（所有RDN仅包含属性类型DC）可以映射回域名。请注意，本文档没有为任何其他可分辨名称定义域名等效。
The DC (short for domainComponent) attribute type is defined as follows:
DC（domainComponent的缩写）属性类型定义如下：
( 0.9.2342.19200300.100.1.25 NAME 'dc' EQUALITY caseIgnoreIA5Match SUBSTR caseIgnoreIA5SubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.26 SINGLE-VALUE )
（0.9.2342.19200300.100.1.25名称“dc”相等caseIgnoreIA5Match SUBSTR caseIgnoreIA5SubstringsMatch语法1.3.6.1.4.1.1466.115.121.1.26单值）
The value of this attribute is a string holding one component of a domain name. The encoding of IA5String for use in LDAP is simply the characters of the string itself. The equality matching rule is case insensitive, as is today's DNS.
此属性的值是一个字符串，其中包含域名的一个组件。LDAP中使用的IA5String的编码只是字符串本身的字符。与今天的DNS一样，相等匹配规则不区分大小写。
An object with a name derived from its domain name using the algorithm of section 3 is represented as an entry in the directory. The "DC" attribute is present in the entry and used as the RDN.
使用第3节的算法从其域名派生名称的对象表示为目录中的一个条目。条目中存在“DC”属性，并用作RDN。
An attribute can only be present in an entry held by an LDAP server when that attribute is permitted by the entry's object class.
只有当LDAP服务器持有的条目的对象类允许该属性时，该属性才能出现在该条目中。
This section defines two object classes. The first, dcObject, is intended to be used in entries for which there is an appropriate structural object class. For example, if the domain represents a particular organization, the entry would have as its structural object class 'organization', and the 'dcObject' class would be an auxiliary class. The second, domain, is a structural object class used for entries in which no other information is being stored. The domain object class is typically used for entries that are placeholders or whose domains do not correspond to real-world entities.
本节定义了两个对象类。第一个是dcObject，用于有适当结构对象类的条目中。例如，如果域表示一个特定的组织，则条目将具有作为其结构对象类的“organization”，而“Dobject”类将是一个辅助类。第二个域是一个结构对象类，用于不存储其他信息的条目。域对象类通常用于作为占位符或其域与实际实体不对应的条目。
The dcObject object class permits the dc attribute to be present in an entry. This object class is defined as auxiliary, as it would typically be used in conjunction with an existing structural object class, such as organization, organizationalUnit or locality.
dcObject对象类允许dc属性出现在条目中。该对象类被定义为辅助对象，因为它通常与现有的结构对象类（如organization、organizationalUnit或Location）结合使用。
The following object class, along with the dc attribute, can be added to any entry.
以下对象类以及dc属性可以添加到任何条目中。
( 1.3.6.1.4.1.1466.344 NAME 'dcObject' SUP top AUXILIARY MUST dc )
（1.3.6.1.4.1.1466.344名称“dcObject”辅助必须为dc）
An example entry would be:
一个例子是：
dn: dc=critical-angle,dc=com objectClass: top objectClass: organization objectClass: dcObject dc: critical-angle o: Critical Angle Inc.
dn:dc=临界角度，dc=com对象类：顶级对象类：组织对象类：dcObject dc:临界角度o:临界角度公司。
If the entry does not correspond to an organization, organizational unit or other type of object for which an object class has been defined, then the "domain" object class can be used. The "domain" object class requires that the "DC" attribute be present, and permits several other attributes to be present in the entry.
如果条目与已定义对象类的组织、组织单位或其他类型的对象不对应，则可以使用“域”对象类。“域”对象类要求“DC”属性存在，并允许条目中存在其他几个属性。
The entry will have as its structural object class the "domain" object class.
条目的结构对象类为“域”对象类。
( 0.9.2342.19200300.100.4.13 NAME 'domain' SUP top STRUCTURAL MUST dc MAY ( userPassword $ searchGuide $ seeAlso $ businessCategory $ x121Address $ registeredAddress $ destinationIndicator $ preferredDeliveryMethod $ telexNumber $ teletexTerminalIdentifier $ telephoneNumber $ internationaliSDNNumber $ facsimileTelephoneNumber $ street $ postOfficeBox $ postalCode $ postalAddress $ physicalDeliveryOfficeName $ st $ l $ description $ o $ associatedName ) )
（0.9.2342.19200300.100.4.13名称“域”辅助结构必须为dc-MAY（用户密码$searchGuide$另请参见$businessCategory$X121地址$registeredAddress$destinationIndicator$preferredDeliveryMethod$telexNumber$teletexTerminalIdentifier$telephoneNumber$internationaliSDNNumber$facsimileTelephoneNumber$street$postOfficeBox$postalCode$postalAddress$physicalDeliveryOfficeName$st$l$d说明$o$associatedName）
The optional attributes of the domain class are used for describing the object represented by this domain, and may also be useful when searching. These attributes are already defined for use with LDAP [4].
域类的可选属性用于描述由该域表示的对象，在搜索时也可能有用。这些属性已定义为与LDAP一起使用[4]。
An example entry would be:
一个例子是：
dn: dc=tcp,dc=critical-angle,dc=com
objectClass: top
objectClass: domain
dc: tcp
description: a placeholder entry used with SRV records
dn: dc=tcp,dc=critical-angle,dc=com
objectClass: top
objectClass: domain
dc: tcp
description: a placeholder entry used with SRV records
The DC attribute is used for naming entries of the domain class, and this can be represented in X.500 servers by the following name form rule.
DC属性用于命名域类的条目，这可以在X.500服务器中通过以下名称形式规则表示。
( 1.3.6.1.4.1.1466.345 NAME 'domainNameForm' OC domain MUST ( dc ) )
（1.3.6.1.4.1.1466.345名称'domainNameForm'OC域必须（dc））

This memo describes how attributes of objects may be discovered and retrieved. Servers should ensure that an appropriate security policy is maintained.
本备忘录描述了如何发现和检索对象的属性。服务器应确保维护适当的安全策略。
An enterprise is not restricted in the information which it may store in DNS or LDAP servers. A client which contacts an untrusted server may have incorrect or misleading information returned (e.g. an organization's server may claim to hold naming contexts representing domain names which have not been delegated to that organization).
企业可能存储在DNS或LDAP服务器中的信息不受限制。与不受信任的服务器联系的客户端可能返回了错误或误导性的信息（例如，组织的服务器可能声称拥有表示未委托给该组织的域名的命名上下文）。
