EAP Chaining user, machine, rsa with iSE

Hi,
Is there any way to configure the following using ISE and Anyconnect/NAM module:
eap-chaining:
1. USER auth, Machine fail = Internet (works)
2. User auth, Machine auth = limited corporate (works)
3. User auth, Machine auth, RSA auth = Full (not sure about this one)
Ideally we'd like the RSA prompts to appear on the successful completion of user/machine auth.
Alternatively can we prompt RSA, and it that fails still test User/Machine?
Thanks,

Please check the following document, will be helpful in your scenarios,

Apple macosx machine authentication with ISE using EAP-TLS

Hello,
On a ongoing setup we are using eap-tls authentication with account validation against AD. We have our own CA (microsoft based). ISE version 1.2.1 patch 1.
With windows machines all is working well. We are using computer authentication only.
Now the problem is that we wish to do the same with MAC OSX machines.
We are using casper software suite and are able to push certificates into macosx, and are doing machine authentication.
in ISE the certificate authentication profile is being set to look at the subject alternative name - DNS name of the machines. Whenever we set it to the UPN (hostname$) windows accounts are not found in ad.
When MAC OSX authenticate as machines (they have a computer account in AD) they present themselves with RADIUS-Username = hostname$ instead of host/hostname.
The consequence is that by lacking the host/, ISE considers that this is a user authentication, instead of a computer one, and when it sets off to find the account, it searches in User class instead of Computer - which obviously returns no results.
Is anybody aware of any way to force MAC OSX to present a host/hostname RADIUS-Username when authenticating?
Any similar experiences of authenticating MAC OSX with ISE and machine/computer authentication are welcome.
Thanks

Additional information from the above question.
I have the following setup;
ACS 3.2(3) built 11 appliance
-Cisco AP1200 wireless access point
-Novell NDS to be used as an external database
-Windows 2003 enterprise with standalone Certificate Authorithy Services Installed
-Windows XP SP2 Client
My Goal is to use Windows XP Native Wlan Utility to connect to AP using EAP-TLS authentication against Novell NDS.
Tried to connect using Cisco compatible wlaN utility and authenticate using EAP-GTC against Novell NDS for for users, it works fine and perfectly.
When connecting using EAP-TLS, I am getting an error from ACS failed attempt "Auth type Not supported by External DB". But in the ACS documentation says that it supports EAP-TLS. How true is this? Is there anybody have the same problem? Do I need to upgrade my ACS? What should I do? What other authentication type could be used to utilize native WinXP Wlan Utility?
Please help...
Thanks

User Based Authorization with ISE

I am trying to configure ISE to limit the activitiy of individual users once they have logged in from an authorized PC into our netowrk. We basically only want them to be able to connect to specific systems. Is ISE able to do this on a per user basis?

Yes.
One of the things you can do via your Authorization policy is to push a downloadable ACL (dACL) to the port (for wired users). For wireless users you can apply a pre-defined Airespace ACL from the WLC to the user session.

Machine authentication with Windows 7

Version: ISE 1.2p12
Hello,
I'm doing user and machine authentication with ISE.
I use a first authorization rule to authenticate the machine against the AD. If it's part computers of the domain.
Then I use an authorization rule to check if the user's group in AD with the credential he used to open the session + "Network Access:WasMachineAuthenticated = True"
Things seems to be working and I see my switch port is "Authz Success" but shortly after the Windows 7 machine is behaving like 802.1X authentication fails. The little computer on the bottom right has a cross on it.
If I disable and enable again the network card of that windows machine it works.
Does any one of you have an idea about this problem ? something to tweak on Windows 7 like timers...
Thank you

Hi Mika. My comments below:
a) You told me that MAR ("Network Access:WasMachineAuthenticated = True") has some drawbacks. When hibernation is used it can cause problems since the MAC address could have been removed from the cache when the user un-hibernate its computer. Then why not increasing the MAR cache to a value of 7 days then ? Regarding the roaming between wire and wireless it's a problem indeed.
NS: I don't believe that the MAR cache would be affected by a machine hibernating or going to sleep. There are some dot1x related bug fixes that Massimo outlined in his first pos that you should look into. But yes, you can increase the MAR timer to a value that fits your environent
b) You suggest to use one authorization rule for the device which should be part of the AD and one authorization rule for the user with the extra result "IdentityAccessRestricted = False". By the was, are we really talking about authorization rules here ? I will try this but it's difficult for me to imagine how it would really work.
NS: Perhaps there is some confusion here but let me try to explain this again. The "IdentityAccessRestricted" is a check that can be done against a machine or a user account in AD. It is an optional attribute and you don't have to have it. I use it so I can prevent terminated users from gaining access to the network by simply disabling their AD account. Again, that account can be either for a "user" or for a "machine"
z) One question I was asking myself for a long time. All of us want to do machine+user authentication but Windows write Machine OR User Authentication. This "OR" is very confusing.
NS: At the moment, the only way you can accomplish a true machine+user authentication is to use the Cisco AnyConnect supplicant. The process is also known as "EAP-Chaining" and/or "EAP-TEAP." In fact there is an official RFC (RFC 7170 - See link below). Now the question is when and if Microsoft, Apple, Linux, etc will start supporting it:

ISE EAP-Chaining with machine, certificate and domain credentials

Good morning,
A customer wants to do the following for their corporate wireless users (all clients will be customer assets):
Corp. wireless to authenticate with 2-factor authentication:
•1. Certificate
•2. Machine auth thru AD
•3. Domain creds
When client authenticates, they want to match on 2 out of the 3 conditions before allowing access.
Clients are Windows laptops and corporate iPhones.
Certs can be issued thru GPO and MDM for iPhones
Client supplicant on laptops is native Windows - which I understand is a compatibility issue from this thread: https://supportforums.cisco.com/thread/2185627
My first question is: can this be done?
Second question: how would i implement this from an AuthC/AuthZ perspective?
Thanks in advance,
Andrew

You can do this configuring anyconnect with NAM modules on endpoints! But I don't make sense configure some clients with certificate and others with domains credentials...
For your information, I'm actually configuring EAP-Chaining on ISE 1.2 and i'm gotting some problems. The first one I got with windows 8, for some reason windows was sending wrong information about the machine password but I solved the problem installing a KB on windows 8 machines (http://support.microsoft.com/kb/2743127/en-us). The second one I got with windows 7 that are sending information correctly about domain but wrong information about user credentials, on ISE logs I can see that windows 7 are sending user "anonymous" + machine name on the first longin... after windows 7 start if I remove the cable and connect again the authentication and authorization happen correctly. I still invastigate the root cause and if there is a KB to solve the problem as I did with windows 8.
Good luck and keep in touch.

EAP Chaining with Machine TLS and User PEAP

We are deploying an ISE based .1x. The design is to use eap-tls for machine and eap-peap for user. Apparently EAP-Chaining is recommended, but can anyone confirm if we can do chaining based on machine TLS and user PEAP. I have done some investigation and could not find any supporting document, but not any document saying not supporting either. Looking at Anyconnect profile editor, it does not look like this configuration is supported. Has anyone done this before?
Thanks a lot.

Just change the authentication policy to allow the methods you want to use under eap-fast (eap-chaining) and use the same ones in your nam client configuration settings.

[ISE] EAP-chaining by using EAP-TLS internal authc for machine cert & user cert

Hi Guys,
I'm taking the EAP-chaining into our enterprise workspace authenticaiton, now i meet following issue:
my anyconnect make the network xml profile which decide the method of eap-fast authencation ,both the machine authc & user authc are use the cert.
Then i found that the client always knock the authoraztion policy about the machine authenticaiton(i set this policy result which is permit access), i believe the " EAP-fast result machine & user are passed " , even though its result using the dacl "permit all", but it doesn't knock the following policy.
and about the result of machine authentication , i set the "permit access" , is it too loose? but i check the instance and cisco document , everyone told me that this policy rusult " permit access".
it would be appreciated that anyone can help this issue.
lately i will upload my policy and live authencation pic catch. Thanks.

ISE 1.2 - MAR cache with PEAP vs EAP Chaining

Does EAP chaining with EAP-FAST v2 and NAM 3.1 present the machine certificate for authentication during each connection to wireless? It's not still tied to the windows log in event as with PEAP?
I found this article, but would like to see if anyone has experience working with EAP chaining in ISE.
https://tswireless.wordpress.com/2012/09/22/cisco-ise-machine-authentication-cache/

Yes if you set up NAM for EAP-Chaining - Machine and User, and then select EAP-TLS w/cert, nam will send both when a user logs in. When the machine is booting only the machine identity will be sent (because we don't know the users identity before they have attempted to log in).

Machine and User authentication with ISE 1.2.1

Hi ,
Can any one tell me in machine authentication what access need to be enable DACL for machine logon?
Can we enable the access on port level ? direct to tcp/udp or ip level what is the best practice.
Thanks
Pranav

is this what you are looking for EAP Chaining which uses a machine certificate or a machine username / password locked to the device through the Microsoft domain enrollment process. When the device boots, it is authenticated to the network using 802.1X. When the user logs onto the device, the session information from the machine authentication and the user credentials are sent up to the network as part of the same user authentication. The combination of the two indicates that the device belongs to the corporation and the user is an employee.

ISE 1.2 EAP Chaining and Windows 8 - Auth failures

Hi All,
I've got a couple sites that appear to have issues with EAP chaining, ISE 1.2 and Anyconnect client on windows 8 enterprise.
Basically the windows 8 machines authenticate intermittently and randomly but largely fail auth.
Often the client will work perfectly for a boot even after a few reboots etc and then might stop working. Other clients won't work at all no mater what settings you configure.
Outer Method - EAP-FASTv2
Inner Method - MSChapV2
ISE 1.2 with Patch 1 (latest)
Windows 8 Enterprise - with patch http://support.microsoft.com/kb/2743127
Anyconnect Client 3.1.0466 (latest)
Machine and User Auth Against AD.
Cert checks disabled for testing.
Clients using same configuration.xml file
Symptom is Anyconnect prompts for username / password instead of using existing credentials. Typing credentials doesn't work.
Logs show failed "anonymous" authentications or client EAP timeouts.
Cheers
Peter.

Hi Peter,
It sounds like the Inner Method is not being negotitated properly so its only reading the Outer Method which by default is set to show "Anonymous" in AnyConnect Profiles.
Is it possible to upload a PDF version or copy paste the output of the failure from ISE's perspective?
Kind Regards,
Vlad

AD Machine Authentication with Cisco ISE problem

Hi Experts,
I am new with ISE, I have configured ISE & Domain computers for PEAP authentication. initially machine gets authenticated and then starts going MAB.
Authentication policy:
Allowed protocol = PEAP & TLS
Authorization Policy:
Condition for computer to be checked in external identity store (AD) = Permit access
Condition for users to be checked in external identity store (AD) plus WasMachineAuthenticated = permit access
All of the above policies do match and download the ACL from ISE but computer starts to mab authentication again...
Switchport configuration:
===============================================
ip access-list extended ACL-DEFAULT
remark Allow DHCP
permit udp any eq bootpc any eq bootps
remark Allow DNS
permit udp any any eq domain
permit ip any host (AD)
permit icmp any any
permit ip any host (ISE-1)
permit ip any host (ISE-2)
permit udp any host (CUCM-1) eq tftp
permit udp any host (CUCM-2)eq tftp
deny ip any any
===============================================
switchport config
===============================================
Switchport Access vlan 10
switchport mode access
switchport voice vlan 20
ip access-group ACL-DEFAULT in
authentication open
authentication event fail action next-method
authentication event server dead action authorize vlan 1
authentication event server alive action reinitialize
authentication host-mode multi-domain
authentication order dot1x mab
authentication priority dot1x mab
authentication port-control auto
authentication periodic
authentication timer reauthenticate server
authentication timer inactivity 180
authentication violation restrict
mab
dot1x pae authenticator
dot1x timeout tx-period 100
====================================================
One more problem about the "authentication open" and default ACL. Once the authentication succeeds and per user is ACL pushed though ISE to the switch. The default ACL still blocks communication on this switchprort.
Your help will highly appreciated.
Regards,

You need to watch the switch during an authentication, see if the machine is passing authentication and the user may be failing authentication causing the switch to fail to mab. If your switch configuration is on auth failure continue to next method, then this makes sense. The question is why is the user failing auth but the machine is passing, could be something in the policy. Make sure your AD setup has machine authentciation checked or it may not tie the machine and user auth together and the user may be failing because ISE can't make that relationship so the machinewasauth=true is not beeing matched. Easy way to check is remove that rule from your policy and see if the same thing happens.
I've also seen this happen when clients want to use EAP-TLS on the wired, machines passes auth, then the user logs into a machine for the first time. The user auth kicks off before the user gets a cert and fails auth with a null certificate, since this is a auth failure the switchport kicks over to MAB.
I don't think wasmachineauth=true is that great, I prefer to use EAP-FASTv2 using Cisco Anyconnect NAM with eap-chaining. This is great because you can do two part authentication. EAP-FAST outer with EAP-TLS inner for the machine auth, and MSCHAPv2 for the inner of the user auth. You get your EAP-TLS auth for the machine and don't have to worry about a user logging into a machine for the first time and switching to MAB because the user doesn't have a cert yet. I also do my rule to say if machine pass and user fail, then workstaion policy, if machine and user pass then corp policy.

ISE 1.1.1 - EAP-TLS / User Cert - Determine if corporate laptop?

Greets. Is there a way to determine if the machine a user has authenticated from via EAP-TLS / user cert (or PEAP / mschapV2) is an active directory computer or not. I understand that EAP-Chaining using EAP-FAST and the Anyconnect client would work for this, but what about using the native windows supplicant and a user cert (or PEAP / mschapv2)?
Long story short, what I'd like to do is:
User authenticates to ISE via EAP-TLS / user cert (or PEAP / mschapV2)
Authorization based on whether it's a personally owned device or a corporate laptop (different AuthZ rule/ACL's based on this)
personally owned devices only allowed to do ICA,
corporate device can use SQL, RDP, etc...
Thoughts, ideas?

Not sure i understand your response, or perhaps my original question isn't clear.
User authenticates with EAP-TLS / User cert
User is authorized based on user cert CN Name, Active Directory lookup, group membership matched, and proper ACL applied
Unable to determine if the machine that the user is authenticating from is an active directory computer or not which would need to be determine in order to allow further ACL refinement (permit/deny certain protocol's based on if it is a personally owned device or a domained device, etc...).
My question is, is it possible to do this using the native windows suplicant and EAP-TLS / user? I am only able to look up details based on the user cert (since this is what the supplicant is using), and not sure how to validate the PC as being a member of the domain or not (since the machine cert wasn't used in EAP-TLS).

EAP TLS for machine and EAP PEAP for user

Hi forum
I am doing a design to use ISE to enforece dot1x for corporate machinese on both wired and wireless.
Due to the particular environment, we will need to use EAP-TLS for machines auth and on top of that use EAP-PEAP for user auth with windows credential and posture for full access.
Just wondering if anyone has done this before:
1. Will this work?
2. Any gottas?
3. what is the user experience like?
All machines are win7 based.
Thanks

You can not use the native supplicant for this. Cisco Anyconnect NAM will allow you to use this method. It is very simple to configure and deploy.

EAP Chaining with Cisco ACS 5.x and the Cisco Anyconnect NAM Client

Hi Guys,
Whilst I’m well aware of the limitations of the built in the windows Wireless 802.1x supplicant. Is there a way, using the NAM client to authenticate both a computer and a user simultaneously, when used for authentication to wireless networks?
As has been posted many times before on this forum, this isn’t possible due to windows not authenticating with the 'computer account' whilst the user is logged in, but with the NAM client it seems possible to do both user and computer authentication based on the options it gives you with EAP-Fast and 'EAP Chaining'.
Can anyone validate this is possible? I have the design guide for exactly this for Cisco ISE but i need it to work on ACS (5.x).
Thanks in advance.
SteveH

Bobby, I ran into the same issue with the "15015 Could not find ID Store" issue. It turned out to be an issue with communication between the ACS and AD. It looked like AD was connected successfully, but until I rebooted ACS, I kept getting the same error. It was like it couldn't see the AD security groups even though it could scan the AD tree successfully.
So, try rebooting ACS if you haven't already and see if that resolves the error.

Limit the number of session per user in the Wired dot1x environment with ISE 1.2

Hello,
I need to check if there is any configuration/workaround to limit the number of sessions/access per user in the Wired dot1x configuration.
I need to check if this feature is available or not to solve the following scenario:
I have 2 SW ports configured to use dot1x authentication with ISE 1.2 server.
If user A connects to the 1st port and authenticated then he will placed on a VLAN based on the authorization profile.
The case, that I need to deny the same user to connect on a different machine with the same credentials.
The ISE itself does not have this feature currently, the only feature available is to limit the number of sessions for the guest user.
Is there any workaround on the Cisco switches to solve this? Cisco WLC has this feature and for the VPN we can limit the number of sessions also from the ASA itself.
Thanks.

limit number of session per user using wired dot1x is not available in 1.3
