(PAM) The new industry standard integrated
login
framework. PAM is used by system entry components, such as
the
Common Desktop Environment's dtlogin, to authenticate
users logging into a
Unix system. It provides pluggability
for a variety of system-entry services. PAM's ability to
stack authentication modules can be used to integrate
login with different authentication mechanisms such as
RSA,
DCE and
Kerberos, and thus unify login mechanisms.
PAM can also integrate
smart card authentication.
