Hi all,

 

My eap-tls authentication and authorization policy do not work , this my rule:

 

Authentication:

WIREDDEVICE:

Device Type EQUALS Device Type#All Device Types#Swicth Cisco

AND
Radius:NAS-Port-Type EQUALS Ethernet

Authorization:

WIRED-MACHINE if (Wired_802.1X AND ADTP2:ExternalGroups EQUALS tp2.it/Users/Domain Computers
AND Network Access:EapTunnel EQUALS PEAP
AND Network Access:EapAuthentication EQUALS EAP-TLS )
then WIRED_AD_ONLY
 
 WIRED-USER if (Wired_802.1X AND ADTP2:ExternalGroups EQUALS tp2.it/Users/Domain Users
AND Network Access:WasMachineAuthenticated EQUALS True
AND Network Access:EapTunnel EQUALS PEAP
AND Network Access:EapAuthentication EQUALS EAP-TLS )
then WIRED_PERMIT_ALL
 
Default if no matches, then DenyAccess
 
This is my error generated from ISE:

Why do you have PEAP in your authz rules, if your doing EAP-TLS?, this will never match, you can't do both in the same rule.

Also, don't expect "WasMachineAuthenticated" to work properly, it's not a very stable feature. You should look into Cisco AnyConnect NAM and EAP-Chaining.

 

WIRED-MACHINE if (Wired_802.1X AND ADTP2:ExternalGroups EQUALS tp2.it/Users/Domain Computers

AND Network Access:EapTunnel EQUALS PEAP
AND Network Access:EapAuthentication EQUALS EAP-TLS )
then WIRED_AD_ONLY
 
 WIRED-USER if (Wired_802.1X AND ADTP2:ExternalGroups EQUALS tp2.it/Users/Domain Users
AND Network Access:WasMachineAuthenticated EQUALS True
AND Network Access:EapTunnel EQUALS PEAP
AND Network Access:EapAuthentication EQUALS EAP-TLS )
then WIRED_PERMIT_ALL

I think jan is right, choose EAP-TLS or PEAP, not both.

However your rule is failing on the WasMachineAuthenticated attribute. This is not a very good feature and pretty much fails when using more than one PSN. The problem being machine authc happens with one PSN and gets logged, user authc happens with the other and the machine log authc that is checked does not replicate between PSNs and so fails.
