Active Directory Domain

This option represents the active directory domain that is configured in the
Microsoft Active Directory server. This option is only valid if you have chosen a
Microsoft Active Directory as the LDAP server type. E.g.: test.domain.com

Using the RADIUS Server

RADIUS (Remote Authentication Dial In User Service) is a protocol specified by the
Internet Engineering Task Force (IETF) working group. There are two specifications that
make up the RADIUS protocol suite: Authentication and Accounting. These specifications
aim to centralize authentication, configuration and accounting for dial-in services to an
independent server. The RADIUS protocol exists in several implementations such as
freeRADIUS, openRADIUS or RADIUS on UNIX systems. The RADIUS protocol itself is
well specified and tested. We can give a recommendation for all products listed above,
especially for the free RADIUS implementation.

Note:

Currently, we do not support challenge/response. An Access Challenge response is

seen and evaluated as an Access Reject.

To access a remote device using the RADIUS protocol you have to login, first. You are
asked to specify your user name and password, then. The RADIUS server reads your input
data (Authentication) and the CAT5 8-PORT/16-PORT IP-KVM looks for your profile
(Authorization). The profile defines (or limits) your actions and may differ depending on
your specific situation. If there is no such profile your access via RADIUS will be refused.
In terms of the remote activity mechanism the login via RADIUS works similar to the
Remote Console. If there is no activity for half an hour your connection to the CAT5
8-PORT/16-PORT IP-KVM will be aborted and closed.

Server

Enter either the IP address or the hostname of the RADIUS Server to connect to. For
the hostname DNS has to be configured and enabled.

Shared Secret

A shared secret is a text string that serves as a password between the RADIUS client
and RADIUS server. In this case the CAT5 8-PORT/16-PORT IP-KVM serves as a
RADIUS client. A shared secret is used to verify that RADIUS messages are sent by a
