Note:
If a RADIUS server is used, the name assigned to a VPNremote Client must be 
identical to the one used in the RADIUS server.
A popular tool for managing authentication and accounting for remote access has been Remote 
Authentication Dial-In User Service (RADIUS)
. Use the Policy Manager for RADIUS/ACE if you 
want to use one or more RADIUS servers to authenticate remote users. A security gateway can 
query up to three RADIUS servers, where two of the servers is recognized as backups.

Note:
The security gateway must authenticate itself to the RADIUS server with a 
“shared secret” before they can exchange information. Therefore, the RADIUS 
server must be configured with a shared secret for the security gateway.
