Prepare the RADIUS Server

Set up the RADIUS server and then configure the RADIUS server to accept RADIUS requests from the VMware Identity Manager service.

Refer to your RADIUS vendor's setup guides for information about setting up the RADIUS server. Note your RADIUS configuration information as you use this information when you configure RADIUS in the service. To see the type of RADIUS information required to configure VMware Identity Manager go to Configure RADIUS Authentication in VMware Identity Manager.

You can set up a secondary Radius authentication server to be used for high availability. If the primary RADIUS server does not respond within the server timeout configured for RADIUS authentication, the request is routed to the secondary server. When the primary server does not respond, the secondary server receives all future authentication requests.
