Validity of a certificate chain is confirmed by retrieving the issuer's certificate (by default from the certificate's AIA path) and comparing the issuing certificate's subject key identifier (SKI) entry with the issued certificate's AKI entry.

As discussed in part 2 of this series, the SKI is populated with one of three values: the serial number of the certificate, a unique ID assigned by the signing CA, or any manner of identification listed as part of the General Name data type.

topic=/help.domino.admin.doc/DOC/H_KEY_USAGE_EXTENSIONS_FOR_INTERNET_CERTIFICATES_1521_OVER.html): In addition to validating the identity of the certificate holder an application may validate the purpose that the certificate is authorized for to ensure it is valid for its current use.

This validation is what prevents any non-CA certificate from acting as a certification authority and issuing certificates.

As discussed in my post on the X.509 certificate, any version 3 certificate signed by a certification authority should have at least one entry under the "Authority Information Access" pointing clients towards a location where they can obtain the certificate of the signing CA to validate the relationship.

This path should be available to all clients that may need to validate certificates issued by or chaining to the CA.

Later, when version 3 of the X.509 standard was passed, the "Subject Alternative Name" (sometimes referred to as a "SAN" field) was added allowing the issuer additional flexibility in specifying the identity of the authenticating entity.

Out-of-the-box this provided options to identify the certificate owner in any of the following ways (ref:

This field contains the X.500 address (also referred to as the LDAP distinguished name) of the object whose identity is being asserted.

As mentioned in my previous blog entry on the X.509 certificate, this is a throw back to the roots and original intent for PKI: directory services.

By default, an Active Directory Certificate Services (ADCS) enterprise CA will publish its certificate to the Active Directory configuration partition which is automatically replicated to all domain controllers in the forest.
