PAM can certainly provide an authentication services for those protocols which don't provide user-to-service or user-to-user authentication themselves (although my policy is to deprecate such protocols altogether), but authenticated protocols need to be built at a different layer. That's where SSL/TLS, SASL, GSSAPI, and SSH (the protocol) come in. Unfortunately, SSH was designed as a monolithic entity and thus has to explicitly provide for every authentication mechanism in the protocol, whereas SASL, GSSAPI, and TELNET authentication were designed to be pluggable from the start. -GAWollman -- Garrett A.
