Yeah...
Bringing the switch down to 12.2.44 code seemed to change the way it reported 
the port status. But not without a decrease in verbosity. I don't see any 
output on the console for authentication results with console logging set to 
debugging. The switch only reports that its port line protocol went up and the 
port went into an authorized status.
No comments again and I'm more and more inclined to think that Cisco has to 
give a special privilege to those who study for CCIE just for finding bugs and 
inconsistencies in their documentation.

Interesting..

Why are you using the image that supports new dot1x commands? Exam is based on 
12.2(44)SE that support the older command set. Can you downgrade it and then 
check.  There is point in troubleshooting on the new image.

Looks like exactly what you asked, Kings:

ACS NAP has a profile created from a template profile - "Agentless Host for L2 
(802.1x fall back)
In the authentication section for this profile the router's MAC address is 
entered into the area "Authenticate MAC with"
ACS creates a record in the Reports -> "Passed Authentications" for this MAC 
address as successful with the associated shared Radius authorization profile.

The switch AAA config portion is as follows:

aaa new-model
aaa authentication login default none
aaa authentication dot1x default group radius
aaa authorization network default group radius
aaa accounting dot1x default start-stop group radius
dot1x system-auth-control

interface FastEthernet0/2   //this is where the router is connected
switchport mode access
authentication order dot1x mab webauth
authentication port-control auto
mab
dot1x pae authenticator
dot1x max-reauth-req 1

radius-server host 10.0.0.100 auth-port 1645 acct-port 1646 key CISCO
radius-server vsa send authentication

Is the MAC address configured in the ACS NAP configured for MAB?

Can you paste your AAA config.

Folks,
Anyone can give me a clue why the switch reports the status of the port 
configured for MAC authentication bypass as "UNAUTHORIZED" ?
Based on the output below the authorization session succeeded but the summary 
for dot1x says it is unauthorized. Is it expected ?
