RADIUS Authentication Methods
Access Server supports RADIUS protocol for three methods. Although it would be wise to use CHAP or MS-CHAP, there are situations where using PAP is situationally as secure as the former methods. One example would be if the VPN does not need to send its traffic over the internet. Then it may be ideal to use PAP in this case.
RADIUS Authentication Methods.
This section allows you to configure the RADIUS servers that will be used for Authentication. Access Server supports the configuration of up to five RADIUS servers.
