Add Published Certificates to Active Directory Containers
Applies To: Windows Server 2008 R2
All certification authority (CA) certificates in the Active Directory domain of the current forest are stored in the NTAuthCertificates container. Enterprise CA certificates are added automatically when a new CA is installed.
If a CA certificate is not added automatically when the new CA is created, such as a stand-alone CA created by a user who is not a member of the Enterprise Admins group, the CA certificate can still be added manually to the NTAuthCertificates container. This process can also be used to add the CA certificate of a non-Microsoft CA that has been used to issue smart card logon or domain controller certificates. By publishing these CA certificates to the Enterprise NTAuth store, the administrator indicates that the CA is trusted to issue certificates of these types.
Membership in Enterprise Admins, or equivalent, is the minimum required to complete this procedure.To add a certificate to the NTAuthCertificates container by using the Windows interface
