Configure the Challenge/Response Authentication Scheme

To implement NT Challenge/Response authentication, you must create an authentication scheme using the Policy Server User Interface.

Note: For more information, see the Policy Server documentation.

Use the following settings when creating an NT Challenge/Response authentication scheme:

In the Scheme Common Setup group box:
Authentication Scheme Type: Windows Template
In the Scheme Type Setup tab:
Server Name: enter the fully qualified domain name, for example:

server1.myorg.com

Target: /siteminderagent/ntlm/smntlm.ntc

Note: The directory should correspond to the virtual directory already set up by the installation. The target file, smntlm.ntc, does not need to exist and can be any name that ends in .ntc or the custom MIME type that you use in place of the default.
In the Advanced tab:
Library: smauthntlm
