PAM is a framework that assists applications in performing what I'll call authentication-related activities. The core pieces of PAM are a library (libpam) and a collection of PAM modules, which are dynamically linked libraries (.so) files in the folder /lib/security.
If the digest created by the server matches the digest created by the client, IIS authenticates the client. IIS uses a subauthentication DLL (iissuba.dll) to authenticate the user, resulting in a network logon. By itself, Digest authentication is only a slight improvement over Basic authentication.
