Server User Manual

Chapter 9 Authentication
AUTHENTICATION
Introduction
The console server is a dedicated Linux computer with a myriad of popular and proven Linux software
modules for networking, secure access (OpenSSH), and communications (OpenSSL), and sophisticated
user authentication (PAM, RADIUS, TACACS+ and LDAP).
 This chapter details how the Administrator can use the Management Console to establish
remote AAA authentication for all connections to the console server and attached serial and
network host devices.
 This chapter also covers how to establish a secure link to the Management Console using HTTPS
and using OpenSSL and OpenSSH to establish a secure Administration connection to the console
server.
9.1 Authentication Configuration
Authentication can be performed locally, or remotely using an LDAP, Radius, or TACACS+ authentication
server. The default authentication method for the console server is Local.
Any authentication method that is configured will be used for authentication of any user who attempts
to log in through Telnet, SSH, or the Web Manager to the console server and any connected serial port
or network host devices.
