PAM is a module that abstracts authentication, it does not authenticate
itself, yet asks "providers" if the information passed to it is correct and
then relays this to the application or tries a different method if this is
allowed.
NSS is an abstraction of cryptographic protocols, applied to a network. In
this schema, it is a transport provider:

Problem with today's modular software: they start with the modules
and never get to the software part.
