|(security)||Pluggable Authentication Module - (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.|
