7. IANA 考虑 (IANA Considerations)
Internet Assigned Numbers Authority (IANA) 已按照以下模板更新 LDAP descriptors 注册表 [BCP64]:
本节记录 RFC 4517 对 LDAP descriptors 注册表的更新. 模板中的 descriptor,object identifier,联系人,usage 和 specification 字段都是注册表内容, 因此应保持原始拼写和格式. 中文说明用于解释这些注册项的作用, 不改变 IANA 记录.

对象标识符 (object identifier) 2.5.13.0 的 descriptor 在 BCP 64 中被错误注册为 objectIdentifiersMatch (多了一个 s). 该项已更改为如下内容, 并引用 RFC 4517.

这些注册项主要涉及 LDAP matching rules (匹配规则). 实现者应按 OID 和 descriptor 精确识别规则, 避免因大小写,复数形式或拼写差异导致互操作性问题.
IANA 更新还纠正了旧 descriptor 中的拼写问题, 因此本节对注册表维护者和 LDAP 实现者都很重要. 客户端,服务器和 schema 工具在展示或解析 matching rule 名称时, 应同时注意短名称和对象标识符之间的对应关系.
