Configuring the Cisco VPN 5000 Client to the Cisco VPN 5000 Concentrator with Cisco Secure UNIX (RADIUS) Authentication.

The Cisco VPN 5000 Concentrator can be configured to authenticate VPN 5000 Clients through Cisco Secure UNIX (CSUNIX) RADIUS. This document assumes that local authentication works prior to adding RADIUS authentication (hence our user localuser in group ciscolocal). Authentication is then added to Cisco Secure UNIX RADIUS for users that do not exist in the local database (user csunixuser is assigned to group csunix by virtue of the attributes returned from the Cisco Secure UNIX RADIUS server).
