EAP-TLS help needed

I have a lab setup and I am trying to get EAP-TLS working. I have ACS 4.2 running on my active directory machine which is also my certificate authority. I obtained a cert for the ACS and installed it, reset the ACS, then edited the certificate trust list and restarted.
I added a user to the AD. I then obtained a cert for my laptop logging into the certsrv as the user and installed it.
I added the user to the ACS.
When I try to connect from the wireless laptop using EAP-TLS with the wireless profile EAP TYPE set to Smart Card or Certificate the connection fails. I have unchecked validate certficate authority with no luck connecting.
When I check the ACS under the failed attemps it says ACS user unknown. This is the same user, all I did was change the EAP type on the laptop.
When I set the EAP type to PEAP I am able to get connected with or without validating the server certificate.
Any help would be greatly appreciated.

802.1x EAP-TLS for wired users with ACS 5.5

Hi All,
We are configuring a new setup for wired users authentication with 802.1x(EAP-TLS). ACS 5.5 we are using as authentication server.
We have added the root CA(internal) certificate and certifcate for ACS signed by CA. Now We want to check the authentication is working or not . I hope both root CA and identity certifcate also we need to install in the laptops. But I am not sure how to download the certifcates for client machine manually from CA.
Kindly suggest on how to get certificates for clients both manually as well as automatically?
Thanks,
Vijay

Hi Vijay,
for the Wired 802.1x (EAP-TLS) you need to have following certificates:
On ACS--- Root CA, Intermediate CA, Server Certificate
On Client-- Root CA, Intermediate CA, User certificate(In case of user authentication) OR Machine certificae(In case of Machine authentication)
I am not sure which third party certificate are you using, If its in house Microsoft or any other certificate server then you need download the client certificate from the server itself.
In case of Microsoft, There will be a template for user certificate. You can select it and create user certificate
This one is an old document, But has steps to configure Machine certificate for the user, You can see the steps to download user certificate if its Microsoft server:
http://www.cisco.com/c/en/us/support/docs/security/secure-access-control-server-windows/43722-acs-eap.html#wc-2
In case You are using the third party certificate serevr , Then you need to check with them on how to download the user certificate

Need configuration guide for EAP-TLS

I need to setup the AP-1200 I have for EAP-TLS. Anyone know of some good documentation that I can use to configure this? I already have the CA and RADIUS servers up and going.
Thanks in advance for your help.

Here are some docs that I used when setting up EAP-TLS with my Cisco 350 APs and Cisco 340/350 wireless client adapters. I made notes in them but they were derived from Cisco support originally. I've found that Win2K clients have more trouble with authenticaion because they must have the 802.11x engine installed (MS update/hotfix) which I've found only can be installed on clients running SP3 (not SP2 or even SP4). Kinda weird. Anyways, you'll probably have the best luck with XP clients because of its native 802.11x support that's built in.
Hope that helps...

Connecting iPads to an Enterprise Wireless 802.1x (EAP-TLS) Network Using Windows Server 2003 IAS

Hi there,
I am asked to deploy iPads on an 802.1x EAP-TLS WiFi network. The customer has a Windows Server 2003 IAS server providing RADIUS. There also is a Windows based CA infrastructure in place. This solution is in production and is already being used by other wireless devices. Could someone please highlight the configuration steps for the iPad deployment? The customer whishes to automate the initial deployment and the renewal of the certificates. I have a basic understanding of 802.1x, RADIUS, Certificates etc. in a Windows infrastructure but I am new to enterprise deployment of iPads. There is no MDM tool in place by the way...
I did find a Microsoft article which I think describes what needs to be done: http://blogs.technet.com/b/pki/archive/2012/02/27/ndes-and-ipads.aspx. This article basically states the following steps:
1. Create a placeholder computer account in Active Directory Domain Services (AD DS)
2. Configure a Service Principal Name (SPN) for the new computer object.
3. Enroll a computer certificate passing the FQDN of the placeholder computer object as a Subject Name, using Web Enrollment Pages or Certificates MMC snap-in directly from the computer (Skip step 4 if you are using the Certificates MMC snap-in)
4. Export the certificate created for the non-domain joined machine and install it.
5. Associate the newly created certificate to the placeholder AD DS domain computer account manually created through Name Mappings
The article then elaborates on specific steps needed for the iPad because it treats all certificates as user certificates. Can someone confirm this behavior??
Regards,
Jeffrey

ISE 1.2 EAP-TLS handshake to external RADIUS

Hi everyone!
I'm trying to implement ISE to authenticate a wireless network using a cisco WLC 5508, I have an ISE virtual Appliance version 1.2 and a WLC 5508 version 7.6 with several 3602e Access Points (20 aproximately).
Right now they are authenticating with a RADIUS Server (which I don't manage, it's out of my scope), the WLC uses this RADIUS Server to authenticate using 802.1x and EAP-TLS (which means the clients need to have a valid certificate and be in the RADIUS database which is integrated to the Active Directory), I can't touch the CA either. So now I need to authenticate using Cisco ISE instead of the RADIUS Server (at least directly), the problem is that for "security" reasons or whatever they don't let me integrate the ISE to the CA, so I added the RADIUS server as an external identity source and made my authentication Policy rule pointing at it, like this:
If: Wireless_802.1X Allow Protocols: Default Network Access Use: RADIUS
Then I added ISE as a RADIUS Server on my WLC and made a Test SSID 802.1X pointing to ISE to authenticate and all that, I did some tests and I got this error:
12520 EAP-TLS failed SSL/TLS handshake because the client rejected the ISE local-certificate
Which means the clients are trying to do the EAP-TLS Process to validate the certificate with the Cisco ISE (but ISE does not have the certificate because they won't let me integrate to the CA directly) so it fails. Is there any way I can do something to redirect that EAP-TLS handshake to the exernal RADIUS Server? Making ISE kind of like a connecting point only for the authentication, I realize it's not the best scenario but giving the circumstances it's the best I can do for now, later on I will add the AD to ISE and start creating some authorization policies based on that, but right now I just want them to authenticate.
Any help is appreciated, thanks in advance!

ISE - EAP-TLS and then webAuth?

Hello everyone!
I have a little bit of a complex dilemma in an ISE deployment and I am trying to lean more on how it works technically. Long story short: I am trying to do both machine and user authentication / authorization (per requirements from our Security department) on a wireless network using iDevices (iPads, iPhones, iTouches) that are shared between users. Just an FYI, I know Apple devices are not intended for “multiple users”; hence, why it is a problem I am trying to solve with CWA.
Hardware:
Cisco ISE VM running 1.1.3.124
WLC 5508 running 7.4.100.0
AP 3602I running 7.4.100.0 / IOS 15.2(2)JB$
iPod Touch version 6.1.3(10B329)
Senario:
•- User Authenticates to SSID that is 802.1x WPA2 AES,
•- Machine is checked by having valid Cert issued by CA and given access to ISE CWA
•- User open’s their browser
•- WLC redirects them to ISE CWA
•- User provides credentials on the portal
•- User to CoA’d to full access network
Rules, NSP is a limited profiling access network. CWA is a limited access network with redirect to centeral web auth on ISE. Standard rule 2 & 3 (which are disabled in this screen shot) are the rules that prove the CWA works on an open SSID.
I have gotten the CWA to work great on an open SSID, however when the process involves EAP-TLS everything works but the redirect. The iPod is properly authorized to the CWA (which is the redirect permission), but when I open a browser the iPod just spins searching for the website; it is never redirected to the ISE. My question is, is this even possible? Is there a trick or order of sequence that needs to be changed? I have been told from a Cisco NCE that specializes in ISE that this “may” or “may not” work, but not given an explanation as to why or why not. And if it’s not possible, why not?
Thank you in advance!
Example, now the user is authorized for CWA, but when a user opens the browser it just sits there spinning.
I checked the WLC “Clients>Details” (from the monitoring page) and I noticed something interesting:

ACS 4.0 EAP-TLS Cert not working

Hey,
so i generated my certificate signing request, took it to my CA, got a cert. From "ACS Certification Authority Setup" i installed it onto my ACS appliance, then from "Install ACS Certificate" installed it (it prepopulated the privkey and password so i assume it got that from the cert file). I then add the CA from the "Edit Certificate Trust List". All this goes off without a hitch.
However when i try to add the "Certificate Revocation List" I am unable to add both LDAP:\\\ and http://. I have confirmed that the http:// is working on the CA, and every indication is that the ldap is working too but i don't know of the tools to test that with.
When i go into "System Configuration"->"Global Authentication Setup"->"Allow EAP-TLS" i get the following error.
Failed to initialize PEAP or EAP-TLS authentication protocol because CA certificate is not installed. Install the CA certificate using "ACS Certification Authority Setup" page.
What exactly is not installed about the Certificate? it's on the ACS server, it's configured and the date range is correct.
I've been banging my head against this all day and could use some suggestions. :)

Ok, i now understand it a little better. I needed to install 2 certificates. the first being the Root CA's certificate in the "ACS Certification Authority Setup" section (i mistakenly thought this was simply where i download my generated cert for the next spot.
The second cert is the one i generated using "Generate Certificate Signing Request", i then took that to my Root CA, generated a cert and installed that along with the private key under "Install ACS Certificate".
Thanks for pointing me in the right direction since the error i was getting wasnt helpful to me.

Authentication eap-tls on ACS or local EAP WLC over Lwapp and 7921

Hi All,
I install WLC to provide Wlan architecture and the project was extended for VoWLAN. we have 7921 and E51 running over the wide WLAN architecture.
Computer using Data over wirless are working over PEAP done by ACS and CA signed certificate + user secret on PC is link to the domain account and secret stay the login and password. Our problem is that user and password is link via ACS to Active Directory. The policy of password is to change frequently.
For the Phone we are actually running authentication over Leap but I'm working to define the best security solution for us.
I confront PEAP and Eap-TLS for now:
1) PEAP check the authentication of ACS via certificate trust and authenticate via MS-Chapv2 and the secret password known by user. My problem here is the phone can only be static what is potentially not acceptable
2) Eap-tls which is the best secured security due to the double side certificate authentication + (login / password) on the phone
so I need to manage here Certificate Management ? I mean I can use either the MIC CA certificate on the phone or User CA defined one which I can put on ACS or Local EAP WLC and the put the ACS CA trust on the Phone.
If I understood well I have to put User.cer and ACS_CA.cer on each phone and pout the User_CA on the ACS ?
I have already Certificate on the ACS signed by CA (like veri-signed) so I must create CSR for any phones to be able to use the same CA ?
I'm thinking to use also the local Eap certificate of Controller to manage all of that to avoid every potential money to pay to the trust CA of ACS
can you help me to know if I understood everything good ? I would be please to exchange experience on that
thanks ;)
bye

I am currently using EAP-TLS authentication on my wireless users using ACS 3.2. I have had that problem before. This is what I did...
Setup a Microsoft Certificate server as my
CA. You can use same machine wih your ACS and CA.
Then, generate certificate signing request from ACS then request a server certificate from CA then copy and install a certificate to ACS. On the ACS, go to global authentication setup check the EAP-TLS cetificate. If it failed to respond means that the server certificate is not properly setup.
On the windows xp clients, connect your machine using wired LAN, then request a certificate from CA(the same CA that you have use to your ACS) using IE (ex. http://CAip/certsrv), but this time request a client certificate. The name you should put when requesting the cert must be you local windows user, use 1024, choose microsoft base cryptographic provider 1.0. then installl the certificate on the client. Verify you client certificate it i was installed properly.
At that poit you should be able to connect you r wireless client using EAP-TLS.

EAP-TLS new user login

Hi!
I´m having a logical misunderstanding about NPS, EAP-TLS and certificates. Maybe you can help me out with this.
In my environment I have AD, NPS, CA and network devices. I´m using successfully Wifi EAP-TLS policy and my Ethernet policies are working aswell. I have two policies for ethernet and for wifi:
1. Computer policy: Conditions are Client Friendly Name (Switches), NAS Port Type (Ethernet), Domain Computer Group
2. User policy: Conditions are Client Friendly Name (Switches), NAS Port Type (Ethernet), Domain Users Group
When I turn on computer it get acces to network (if I have certificate and machine is domain computer). When I log in with user who has a certificate and who is domain user - everything still works. So policies are working! If user don´t have certificate
then connection is disconnected.
Problem is that when I have a new user logging to the machine then it don´t have certificate. And authentication will fail! Is there a way to allow user to request certificate and then try to authenticate? GPO policy is "enroll automatically" turned
on but it will not work cause user log in is using TEMP account and certificate is not enrolled! So new users can´t access to network to download profile if I don´t put the certificate there by myself.
Second question is about PXE an computer certificate. Is there a way to use SCCM/PXE for OSD?
Any help would be appriciated!

EAP-TLS with WLC 5508, Microsoft NPS and custom EKU OID´s

We are trying to implement EAP-TLS with client certificates that have a custom EKU OID to distinguish the WLAN clients. The Microsoft Press Book
Windows Server 2008 PKI and Certificate Security gives an example on how to configure a policy in NPS that matches specific EKU OID´s. At the moment we have two policies that have an allowed-certificate-oid configured that matches the OID´s in our certificates, but our setup is not working as expected. Authentications will only be successful, if the client authenticates with the certificate that is matched by the first policy rule.
For example:
Policy 1: allowed-certificate-OID --> corporate
Policy 2: allowed-certificate-OID --> private
Client authenticates with EKU corporate --> success
Client authenticates with EKU private --> reject
My expectation was, that if Policy 1 will not match the NPS goes over to Policy 2 and tries to authenticate the client.
Has anyone a simmilar setup or can help to figure out what is going wrong?
We have a WLC 5508 with Software Version 7.4.100.0 and a NPS on a Windows Server 2008 R2
regards
Fabian

The policy rejects and the NPS goes to the next policy, only if the user does not belong to the configured group.
This means I need to have one AD group per application policy, but that will not solve my problem. A user could belong to more than one group, depending on how many devices he/she has. It will work with one group only for each user, because the first policy that matches a AD group, the user belongs to, could have a OID that is not in the certificate. This would cause a recejct with reason code 73:
The purposes that are configured in the Application Policies extensions, also called Enhanced Key Usage (EKU) extensions, section of the user or computer certificate are not valid or are missing. The user or computer certificate must be configured with the Client Authentication purpose in Application Policies extensions. The object identifier for Client Authentication is 1.3.6.1.5.5.7.3.2.
The certificate does include this OID but not the custom EKU.

EAP-TLS and ISE 1.1 with AD certificates

Hello,
I am trying to configure EAP-TLS authentication with AD certificates.
All ISE servers are joined to AD
I have the root certificate from the CA to Activie Directory installed on the ISE servers
I created the certificate authentication profile using the root certificate
I have PEAP\EAP-TLS enabled as my allowed protocol

I have self-signed certificates on the ISE servers – do they need to be signed by the same CA as the client?
Any other issues I am missing?

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.

ISE and EAP-TLS

Hi
We're planning on implementing eap-tls for our corporate iPads and in the past I've successfully tested it authenticating against ACS5.3 but now that we've moved to ISE (1.1.1.24) I'm getting an error.
22045 Identity policy result is configured for password based authentication methods but received certificate based authentication request
I've tried two different profiles, one with a certificates and AD credentials and the other one with just certificates but the error message is the same for both.
EAP-TLS is enabled in the 'Default Network Access' authentication result.
Can anyone shine a light on where I'm going wrong?
Thanks
Martin

Martin,
Then that makes sense, since the ISE uses certificate based authentication when using eap-tls the certificate doesnt have the OIDs to support certificate based authentication. Here is a guide that shows the requirements needed in order to authenticate clients via certificates:
http://support.microsoft.com/kb/814394
Here is the comment in the article in this case the IAS is the radius server and the same holds true for ISE:
The IAS or the VPN server computer certificate is configured with the Server Authentication purpose. The object identifier for Server Authentication is 1.3.6.1.5.5.7.3.1.
Here is the Cisco eap-tls deployment guide which references the same as above:
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_white_paper09186a008009256b.shtml#wp39121

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

Cisco ISE for 802.1x (EAP-TLS)

I work for a banking organization and security is an area that needs to be improved continuously. I am planning on implementing Cisco ISE for 802.1x together with a Microsoft PKI for certificate issuing and signing.
I am currently trying to implement this in our test environment and I have managed to do a few basic bootstrapping tasks. I need someone to push me into the right direction as to how I can achieve what i am seeking.
I will use Cisco 2900 series switches on the access layer and a few HP switches as well which supports 802.1x.
I want to configure the ISE to process authentication requests using 802.1x EAP-TLS (Certificate Based). All the workstations on the domain needs to authenticate itself using the certificates issued to it by the Certificate Issuing Authority.
I have already managed to get the PKI working and have rolled out the certificates on all the workstations on the test environment. I can't seem to configure the Authentication portion on the ISE.
I request if someone can guide me or direct me to materials that can help achieve the above requirements. The guides available on the Cisco website are overwhelming and I can't seem to figure out how I am supposed to configure the authentication portion.
My email: [email protected]
Cheers,
Krishil Reddy

Hello Mubashir,
Many timers can be modified as needed in a deployment. Unless you are experiencing a specific problem where adjusting the timer may correct unwanted behavior, it is recommended to leave all timers at their default values except for the 802.1X transmit timer (tx-period).
The tx-period timer defaults to a value of 30 seconds. Leaving this value at 30 seconds provides a default wait of 90 seconds (3 x tx-period) before a switchport will begin the next method of authentication, and begin the MAB process for non-authenticating devices.
Based on numerous deployments, the best-practice recommendation is to set the tx-period value to 10 seconds to provide the optimal time for MAB devices. Setting the value below 10 seconds may result in the port moving to MAC authentication bypass too quickly.
Configure the tx-period timer.
C3750X(config-if-range)#dot1x timeout tx-period 10
