2.3.2 Dependencies on Other Systems/Components

The Authentication Services protocols depend on the following systems:

• Active Directory [MS-ADOD]

• Public Key Infrastructure (PKI) [MS-CERSOD]

The Authentication Services protocols depend on Active Directory for identity information.

The Authentication Services protocols depend on the certificate authority (CA)/PKI infrastructure for certificate validation, signature validation, and asymmetric cryptography security services. Microsoft clients use the Crypto API 2.0 library for these features.
