//+=====================================================================
// DS DNs:
//
// DomainDN Example (no longer used for Cert server DS objects):
// DC=pksdom2,DC=nttest,DC=microsoft,DC=com
//
// ConfigDN Example:
// CN=Configuration,DC=pksdom2,DC=nttest,DC=microsoft,DC=com
//
// Cert server DS objects reside in Public Key Services container under
// the Configuraton container:
// CN=Public Key Services,CN=Services,<ConfigDN>
//
//
// In the Public Key Services container:
//
// Root Trust container:
// Each Root CA creates a Root Trust object in this container to store trusted
// Root CA certificates downloaded by all DS clients.
// Renewed CAs and CAs on multiple machines using the same CA name may use the
// same Root Trust object, because certs are always added -- they are never
// removed.
//
// CN=Certification Authorities
// CN=CA foo
// CN=CA bar
// ...
//
//
// Authority Information Access container:
// Each CA creates an AIA object in this container to store CA certs for chain
// building. Renewed CAs and CAs on multiple machines using the same CA name
// may use the same AIA object, because certs are always added -- they are
// never removed.
//
// CN=AIA
// CN=CA foo
// CN=CA bar
// ...
//
//
// CRL Distribution Point containers:
// Each CA creates a CDP object in this container for each unique CA key to
// store CRLs for revocation checking. Only one base CRL and zero or one
// delta CRL are stored in each CDP object, due to potential size constraints,
// and because the attribute is single valued. When a CA is renewed and a new
// CA key is generated during the renewal, a new CDP object is created with
// the CA's key index (in parentheses) appended to the CN. A nested container
// is created for each machine with the CN set to the short machine name
// (first component of the machine's full DNS name).
//
// CN=CDP
// CN=<CA foo's MachineName>
// CN=CA foo
// CN=CA foo(1)
// CN=CA foo(3)
// CN=<CA bar's MachineName>
// CN=CA bar
// CN=CA bar(1)
//
//
// Enrollment Services container:
// Each CA creates an Enrollment Services object in this container. A flags
// attribute indicates whether the CA supports autoenrollment (an Enterprise
// CA) or not (Standalone CA). The Enrollment Services object publishes the
// existence of the CA to all DS clients. Enrollment Services objects are
// created and managed by the certca.h CA APIs.
//
// CN=Enrollment Services
// CN=CA foo
// CN=CA bar
// ...
//
// Enterprise Trust object:
// A single Enterprise Trust object contains certificates for all
// autoenrollment-enabled CAs (root and subordinate Entrprise CAs).
//
// CN=NTAuthCertificates
//
