Pluggable Authentication Modules (PAM) Kerberos
Pluggable Authentication Modules (PAM) Kerberos version B.11.11 is a service for
authenticating users or services across an open network. HP-UX 11i provides Kerberos
authentication through a Kerberos-Client product which is a part of the HP-UX base
operating system. Kerberos, the primary authentication mechanism for Windows 2000,
is integrated with Active Directory Service to provide enterprise-wide account
management. This necessitates the implementation of the Kerberos authentication
mechanism on HP-UX as a Pluggable Authentication Module.
Pluggable Authentication Modules (PAM) [OSF RFC 86] is the standard authentication
mechanism, and is easily configurable to support multiple authentication technologies
on HP-UX.
PAM Kerberos provides the PAM mechanism and encryption support.
The PAM service modules were implemented as a shared library, libpam_krb5.1. This
library is built by linking with libkrb5.1, and is therefore not dependent on the
libsys.sl library.
The HP-UX 11i implementation of Kerberos version 5 protocol provides enterprise-wide
strong user authentication. Using encryption during the user authentication process,
Kerberos infrastructure provides privacy and integrity of user login information since
passwords are no longer communicated in clear text over the network.
HP-UX system entry services can work with any Kerberos v5 Server, namely, MIT
Kerberos and Microsoft Windows 2000. Thus, passwords can be effectively unified in an
Intranet with heterogeneous systems such as UNIX and Microsoft Windows 2000.
Furthermore, support of password change protocol automates propagation of password
changes. These two features can significantly reduce user administration complexity in a
heterogeneous environment.
The HP-UX applications using PAM include telnet, login, remsh, ftp, rexec, rlogin,
dtlogin, and rcp. PAM Kerberos interoperates with a Key Distribution Center (KDC)
operating on either a UNIX or a Microsoft Windows 2000 server.
