This property specifies a method for certificate authorities to report invalid certificate requests to the domain name holder using the Incident Object Description Exchange Format. As of 2018 [update] , not all certificate authorities support this tag, so there is no guarantee that all certificate issuances will be reported.
On Microsoft Servers, a domain controller (DC) is a server computer [1] [2] that responds to security authentication requests (logging in, etc.) within a Windows domain. [3] [4] A domain is a concept introduced in Windows NT whereby a user may be granted access to a number of computer resources with the use of a single username and password combination.
The software and operating system used to run a domain controller usually consists of several key components shared across platforms.This includes the operating system (usually Windows Server or Linux), an LDAP service (Red Hat Directory Server, etc.), a network time service (ntpd, chrony, etc.), and a computer network authentication protocol (usually Kerberos).

DNS-based Authentication of Named Entities (DANE) is an Internet security protocol to allow X.509 digital certificates, commonly used for Transport Layer Security (TLS), to be bound to domain names using Domain Name System Security Extensions .
