Table 3-2 New Options on the NAP Protocols Page

Option

Description:

 

 

Use PACs

Click the Use PACs radio button if you want ACS to

 

authenticate clients to which this NAP is applied by using

 

EAP-FAST with PACs enabled.

 

If you click the Use PACs radio button, then the same

 

EAP-FAST configuration options that are available in the

 

global EAP-FAST configuration are available.

 

 

Do Not Use PACs

Click the Do Not Use PACs radio button if you want ACS to

 

authenticate clients to which this NAP is applied by using

 

EAP-FAST without PACs enabled.

 

 

Require Client Certificate

If you click the Do Not Use PACs radio button, the Require

 

Client Certificate option is available. Choose this option to

 

require a client certification for EAP-FAST tunnel

 

establishment.

 

 

Disable Client Certificate Lookup

If you click the Do Not Use PACs radio button, you can check

and Comparisons

the Disable Client Certificate Lookup and Comparisons check

 

box to disable client certificate lookup and to enable

 

EAP-FAST PKI Authorization Bypass.

 

If you check the Disable Client Certificate Lookup and

 

Comparisons check box, ACS establishes an EAP-FAST

 

tunnel without authorizing the user based on user group data or

 

a public key infrastructure (PKI) certificate in a user database;

 

instead, ACS maps the user to a preconfigured user group.

 

 

Assign Group

If you check the Disable Client Certificate Lookup and

 

Comparisons check box; then, from the drop-down list of user

 

groups in the Assign Group field, select a user group to apply

 

to the client.

 

 

Disabling NetBIOS

Because disabling NetBIOS might be desirable in some cases, you can run ACS 4.2 with NetBIOS disabled.

ACS SE 4.2 runs on a customized version of Windows 2003 that includes some but not all Windows 2003 services.

Note Although you can use Windows 2000, Windows XP, and Windows Server 2003 to disable NetBIOS over TCP/IP (NetBT), many corporate networks do not, since most of them still have legacy (Windows 9.x or Windows NT) machines on their network. These machines need NetBIOS to function properly on a network, since they use NetBIOS to log in to domains, find one another, and establish sessions for accessing shared resources.
