Article ID: KB32523 KB Last Updated: 24 Feb 2020Version: 2.0
Summary:

This article explains how to configure SmartPass server with a Windows 2008 NPS server to allow SmartPass administrators and provisioning users to log into the SmartPass server via an external RADIUS server.  The instructions that follow assume there is a working Windows Active Directory environment and Windows 2008 server in place and that you have a working knowledge of both.


Example environment used:
  • Windows 2003 AD with Windows 2008 NPS on separate machines in the same domain. 
  • SmartPass was installed on a separate Windows 2008 server.

 

Solution:

Configuration from the controller:

set service-profile test-web ssid-name TAC-test
set service-profile test-web ssid-type clear
set service-profile test-web auth-fallthru web-portal
set service-profile test-web psk-encrypted <pass>
set service-profile test-web web-portal-form https://10.9.221.250:443/gp2/webportal/ext/webPortalAuthLogin
set service-profile test-web web-portal-acl testacl
set service-profile test-web rsn-ie auth-psk enable
set service-profile test-web attr vlan-name default 
set security acl name testacl permit udp 0.0.0.0 255.255.255.255 eq 68 0.0.0.0 255.255.255.255 eq 67
set security acl name testacl permit ip 0.0.0.0 255.255.255.255 10.9.221.250 0.0.0.0
set security acl name testacl deny 0.0.0.0 255.255.255.255 capture 
set radius server smartpass address 10.9.221.250 auth-port 1818 timeout 5 retransmit 3 deadtime 0 encrypted-key <pass>
set server group smartpass-grp members smartpass
set radius dac smartpass address 10.9.221.250 replay-protect disable encrypted-key 0119130a521b031d701e1d
set authentication web ssid TAC-test ** smartpass-grp
set authorization dynamic ssid TAC-test smartpass
