An intermediate certification authority (CA) is a CA that is subordinate to the root CA by one or more levels and typically issues certificates to other CAs in the public key infrastructure (PKI) hierarchy. The other type of subordinate CA is an issuing CA. For native mode communication to be successful in a Configuration Manager 2007 site, the PKI certificates that are used for authentication, encryption, and signing must successfully chain to a trusted root. Certificate chaining is a native process of the Microsoft Windows operating system that involves collecting all the subordinate CAs up to the root CA and validating each certificate in the path. If one certificate in the chain cannot be located or is found to be invalid (for example, expired), the entire chain will be deemed invalid and Configuration Manager 2007 communication will fail.
