NAC-L2-802.1x (EAP-FAST) and Cisco Secure Services Client 5.0 in wired net

Question

Hi!
(Sorry, if this is a wrong forum.)
Does anybody have any success with Cisco SSC and EAP-FAST in the wired network?
I'm going to use NAC, so I'm trying to set up EAP-FAST. I see the pop-up window on the client to enter user credentials and I see a lot of "debug radius" messages on my 3750 12.2(44)SE switch:
Access-Requests with User-Name="anonymous"
Access-Challenges (I see certificate is sent from ACS)
Access-Reject
CS ACS Failed Attempts Report shows "ACS user unknown" failure for "anonymous".
So far as I understood, EAP-FAST is a tunneled method and it uses "anonymous" to protect user's identity during phase 0 / phase 1 transactions. The actual username is sent in phase 2 transaction.
The following is excerpt from the CS ACS documentation:
"EAP-FAST can protect the username in all EAP-FAST transactions. ACS does not perform user authentication based on a username that is presented in phase one; however, whether the username is protected during phase one depends on the end-user client. If the end-user client does not send the real username in phase one, the username is protected. The Cisco Aironet EAP-FAST client protects the username in phase one by sending FAST_MAC address in place of the username. After phase one of EAP-FAST, all data is encrypted, including username information that is usually sent in clear text."
SSC 5.0 is indeed set up with "Unprotected Identity Pattern"=anonymous and "Protected Identity Pattern"=[username] using sscManagementUtility.exe
So, the question is: Why is ACS 4.1 trying to authenticate username "anonymous" if it knows that the user is fake? Does anybody have working configuaration for EAP-FAST in a wired network?
Any help is greatly appreciated.

Correct, ACS database wasn't selected on the NAP Authentication page. It works now, but I constantly get the following message in the Windows event log: "The Cisco Secure Services Client service hung on starting". This is Windows 2000 Advanced Server system with SP4. SSC was set up with no domain authentication, no machine authentication, single sign-on. After some time the SSC service starts, but at that time my PC is already put into the guest VLAN by the switch (the tx-period is 10 seconds):
POD1-SW#sh run int fa1/0/1
Building configuration...
Current configuration : 378 bytes
interface FastEthernet1/0/1
switchport access vlan 999
switchport mode access
dot1x mac-auth-bypass
dot1x pae authenticator
dot1x port-control auto
dot1x timeout reauth-period server
dot1x timeout tx-period 10
dot1x reauthentication
dot1x critical
dot1x critical recovery action reinitialize
dot1x guest-vlan 91
dot1x critical vlan 11
spanning-tree portfast
end
After all the VLAN is reassigned by the switch, but the delay is too high. How can I troubleshoot this?
Thx.
