Configuring NTLM Authentication and Authorization
You can configure the Firebox SSL VPN Gateway to use Windows NT LAN Manager (NTLM) authentica-
tion to authenticate users against the user database on a Windows NT 4.0 domain controller.
If a user is not located in the user database on the Windows NT 4.0 domain controllers, or fails authenti-
cation, the Firebox SSL VPN Gateway can check for the user name in the Local Users list on the Firebox
SSL VPN Gateway and authenticate the user against the local list if
Use the local user database on the
Firebox SSL VPN Gateway check box is selected on the Settings tab.
A Windows NT 4.0 domain controller maintains domain user accounts in a database on the Windows NT
4.0 server. A domain user account includes a user name and password and other information about the
user.
To configure NTLM authentication, you create an NTLM authentication realm
that includes the address
and port that the Firebox SSL VPN Gateway uses to connect to the Windows NT 4.0 domain controller. You
also specify a time-out value in which an authentication attempt to the server must complete.
When a user logs on to the Firebox SSL VPN Gateway, the user enters the user name and password main-
tained in the domain user account on the Windows NT 4.0 server.
The Firebox SSL VPN Gateway connects to the Windows NT 4.0 server and passes these credentials to
the server. The server authenticates the user.
To configure NTLM authentication
1 Click the Authentication tab.
2 Under Add an Authentication Realm , in Realm name , type a name for
the authentication realm.
If your site has multiple authentication realms, you might use a name that identifies the NTLM realm for which you
specify settings. Realm names are case-sensitive and can contain spaces.
Note
Note: If you want the Default realm to use NTLM authentication, remove the Default realm as described
in “To remove and create a Default realm” on page 70.
