HP-UX PAM RADIUS software provides RADIUS authentication (and authorization) and accounting as PAM authentication and session management modules. PAM allows multiple authentication technologies to coexist. A /etc/pam.conf configuration file determines the authentication module that should be used for a given application, making it transparent to the applications that use the PAM library.

HP-UX PAM RADIUS supports the following modules:

  • Authentication module - This module provides functions to verify the identity of users.
  • Account management module - This module provides functions to perform account management.
  • Session management module - This module provides functions to initiate and terminate sessions.

HP-UX PAM RADIUS is one of the authentication modules that PAM can invoke based on the authentication method defined in /etc/pam.conf PAM configuration file. HP-UX PAM RADIUS enables PAM-capable systems to function as RADIUS clients for authentication and accounting requests for the servers configured in the /etc/raddb/server server configuration file for HP-UX PAM RADIUS. HP-UX PAM RADIUS is based on the PAM Authentication and Accounting module V1.3.17 from FreeRADIUS.

For more information on these modules, see the HP-UX PAM RADIUS A.01.00 Release Notes at the following web address:
