VPN Firewall's Authentication

Users are assigned to a group, and a group is assigned to a domain. Therefore, first create
any domains, then groups, then user accounts.
Note: Do not confuse the authentication groups with the LAN groups that
are described in
You must create name and password accounts for all users who must be able to connect to
the VPN firewall. This includes administrators, guests, and SSL VPN clients. Accounts for
IPSec VPN clients are required only if you have enabled extended authentication (XAUTH) in
your IPSec VPN configuration.
Users connecting to the VPN firewall must be authenticated before being allowed to access
the VPN firewall or the VPN-protected network. The login screen that is presented to the user
requires three items: a user name, a password, and a domain selection. The domain
determines the authentication method that is used and, for SSL connections, the portal layout
that is presented.
Note: IPSec VPN, L2TP, and PPTP users do not belong to a domain and
are not assigned to a group.
Except in the case of IPSec VPN users, when you create a user account, you must specify a
group. When you create a group, you must specify a domain.
The following table summarizes the external authentication protocols and methods that the
VPN firewall supports.

Description
Password Authentication Protocol (PAP) is a simple protocol in which the client sends a
password in clear text.
Challenge Handshake Authentication Protocol (CHAP) executes a three-way handshake
in which the client and server trade challenge messages, each responding with a hash of
the other's challenge message, which is calculated using a shared secret value.
A network-validated PAP or CHAP password-based authentication method that functions
with Remote Authentication Dial In User Service (RADIUS).
A network-validated PAP or CHAP password-based authentication method that functions
with Microsoft Internet Authentication Service (MIAS), which is a component of Microsoft
Windows 2003 Server.
