I don't view PAM as a stop-gap at all. The idea behind PAM is
that applications don't have to know anything about the myriad ways of
authenticating. They just have to know PAM and PAM will take care of
the work of authenticating for them. Today, we have basic user/pass
(with numerous ways of storing the password database), Hesiod,
Kerberos, smart cards, tokens (i.e. key fobs), biometrics, one time
passwords, and probably other methods. How is every application
supposed to support all these methods? How will applications written
today support methods created in the future. Really, it has become
unreasonable to expect applications to support all authentication
methods by themselves without using some intermediary. There is a
standard for an intermediary, and today, it is PAM.
