  • Page 109: Authentication

    4.5.8 Authentication On this screen, you can specify how the DKVM-IP1 will look to authenticate the users. By default, Local Authentication is enabled, which means users will need to use a user account configured on the DKVM-IP1. Alternatively, you can use a RADIUS Server for login authentication. This can be very useful if you already use a RADIUS server to authenticate users for your network, and allows you to use existing authentication information.

  • Page 110

    A shared secret is a text string that serves as a password between the RADIUS client and RADIUS server. In this case, the DKVM-IP1 serves as a RADIUS client. A shared secret is used to verify that RADIUS messages are sent by a RADIUS-enabled device that is configured with the same shared secret to verify that the RADIUS message has not been modified during transit (message integrity).
