Scripting WPA2 EAP+TLS setup (incl. cert)

We have a bunch of Mac OS X users that we'd like to enable WPA2 EAP+TLS for. This would involve setting up the 801.2x connections and distribution of certificates to each machine. We'd like to minimize the effort on the user's part to set it up, so ideally we'd like to be able to package up a script that would install the machine certificate and configure the 802.1x connection for them. I was thinking of some AppleScript to do it.
Any ideas? I'm well aware of the procedure to do it manually (via GUI), but I'm looking to automate the process. I've been googling for an example that either automates it through AppleScript or shows the procedure done entirely at the UNIX command-line (which is fine too).

Perhaps the bottom half of this page would help you glean some command line stuff...

Wireless ISE - 12508 EAP-TLS handshake failed

Hi guys,
I'm in the middle of my very first wireless ISE deployment and I'm hitting issues with EAP-TLS based authentication. In short, all EAP-TLS authentication is failing with the following error. Below that is the relevant excerpt from the logs:
Authentication failed : 12508 EAP-TLS handshake failed
OpenSSLErrorMessage=SSL alert: code=0x233=563 \; source=local \; type=fatal \; message="X509 decrypt error - certificate signature failure", OpenSSLErrorStack= 597863312:error:0D0C50A1:asn1 encoding routines:ASN1_item_verify:unknown message digest algorithm:a_verify.c:146:,
Setup:
- Single standalone ISE 3355 appliance
- Two tier MS enterprise PKI (outside of my direct control)
- WLC 5508
- Windows 7 laptop\
- The ISE has both the root and intermediate CA server certificates installed (individually, not chained) and has an identity certificate from the intermediate CA.
- The test laptop has both the root and intermediate CA server certificates installed (individually, not chained) and has an identity certificate from the intermediate CA.
Now, I'm pretty new to certs so I'm sure I'm missing something simple here. One thing that has come to mind as I'm writing this is that all of the issued certificates are using SHA1 as the Signature hash algorithm but if I remember correctly ISE defaults to SHA-256 when generating a CSR and I can't remember actually changing that. Could my issue be as simple as this, or does this hash algorithm only apply to the CSR process?
This is what TAC came back with, but none of the workarounds helped
Symptom:
========
EAP-TLS auth handshake failing with X509 decrypt error. The error presented to the ISE administrator is "12508: EAP-TLS handshake failed"
Conditions:
=========
EAP-TLS certificate based authentications ISE 1.1.2.145
Workaround:
===========
1) Reboot or restart ISE application service 2) Recreate CAP (Certificate Authentication Profile) 3) Toggle between ID sequence and single ID source

Hi Amjad,
Thanks for the response. I realise that SHA256 is highly preferable, however as per my post the PKI is outside of my direct control so that's a whole other conversation.
Cisco actually recommends avoiding chained certs for ISE, their best practice is that the intermediate and root CA server certificates should be imported into the ISE individually (I don't have a link for this, but it was presented in the Advanced ISE session at Cisco Live this year). On the client side the identity certificate (machine) shows the full trust chain, so I would assume that there isn't an issue there but I'm happy to be corrected.
The certificate format has not been modified in any way. The server and identity certs have been pushed out to the clients via GPO. Tthe root and intermediate certs were exported in DER format directly from each the respective CAs and imported directly in to the ISE
Cheers,
Owen

I have a large customer that is moving into a new building and adding some
new wireless.
They are using a 5508 with 1142's and an ACS server.
They will have the following SSID's
SSID01 -> WPA-EAP-TLS
SSID02 -> WPA2-EAP-TLS (future use)
SSID03 -> Guest Access (internet access only)
They currently use this design across the enterprise which has worked well.
The problem is to get certificates pushed down to the client for the EAP-TLS
they always connect the machine once by wire and log on to the domain so a
GPO pushes the cert to the machine.
This creates a problem that I don't know how to solve as they want to use
iPhones on the new deployment.
Does anyone have any ideas on how to get a cert down to the iPhones for use
with the SSID's?
Thanks in advance for any assistance.

I don't think we can push certs from windows server to iphones . Probably set up a webpage say a accessible from a different ssid from which clients can download and install cert. ?

Nokia E66 EAP-TLS error

Hi, I am configuring a Nokia E66 (wich is v4 in Cisco Compatible Extensions, so it supports EAP-TLS) with WPA2 EAP-TLS against IAS in a Cisco Wireless Network and I always obtain the same error in the IAS event viewer.
denied accesss
Authentication-Type = EAP
EAP-Type = Smart Card or other certificate
Reason-Code = 16
Reason = Authentication was not successful because an unknown user name or incorrect password was used.
Has anybody tried E66 with EAP-TLS?
Any experiences?

Yes, this is my setup
- hidden network
- infraestructure
- security: WPA/ WPA2
- EAP
- Plug -ins: EAP-TLS. I select the user certificate and the CA certificate. User name from the certificate, domain from the certificate
- WPA2 only mode
In the IAS log, the username is correct, but always appear this strange error. The certificates and infraestructure I use it works well in a notebook
Thanks

WRVS4400N Does it support EAP-TLS

Hi our business was looking at purchasing one of these Cisco routers and were curious if it supported WPA2 EAP-TLS?

Jon,
According to the Data Sheet:
Port-based RADIUS authentication (Extensible Authentication Protocol multicast distributed switching [EAP-MDS], Protected Extensible Authentication Protocol [PEAP])

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.
Seth

WPA2 security with EAP-TLS user cert auth

I am investigating the use of EAP-TLS for authenticating clients through a MS NPS radius server for WLC WLAN using WPA-WPA2 for security with 802.1x for auth-key managment. We're trying to decide whether to use PEAP and AD account authentication or require client certificates issued by AD certifcate services. PEAP is working fine if we choose that auth method in our NPS radius network policy, but if we switch this to "smart card or other certificate" for client cert auth it does not work. The wireless profile on the Windows client is set up for WPA2/AES with "Microsoft: smart card or other certificate" for network auth. The 802.1x settings specify "User Authentication" and a user cert for the logged in user from ADCS is installed on the machine. The failure to connect reports "The certificate required to connect to this network can't be found on your computer". When I switch to Computer Authentication the error changes to "Network authentication failed due to a problem with the user account," though a valid machine cert also exists on the computer.
When I attempt to use cert auth I see no auth requests logged on the RADIUS server. I ran MS netmon on both the client and NPS server and I also see no requests coming in from the WLC to NPS. When using PEAP I do see EAP requests and responses between NPS and the WLC and radius requests logged. On the client end I do see an EAP request to the WAP when attempting cert auth, but no messages between the WLC and NPS.
It's also interesting that when I change the WLAN to use 802.1x and WEP encryption for layer 2 auth the cert auth worked first time, though I haven't been able to get that working since. Windows now complains I am missing a cert for that. In any case, what I really want is WPA2/AES with 802.1x cert auth and would like to get this working.
Is anyone using EAP-TLS with MS NPS radius and a WLC successfully? Any ideas on how to troubleshoot this or why I'm not seeing any traffic between WLC and NPS radius when attempting cert auth?

Well Well
WLC or any AAA client acts in pass through mode after initialy generating EAP-identity request so it has nothing to with EAP type. AAA client will behave the same no matter if you use PEAP , EAP-TLS or LEAP .....
The error message that you have reported is clearly sayign that your client doesn't have certificate to submit agains the back-end authentication server and accordingly the process fails . If you are not saying anything sent from WLC to NPS , it makes sense , because when the WLC initialy generate eap-identity request your client fails to answer and accordingly nothing is being sent to NPS server.
In order to verify that we need ' debug client < mac address of the client > ' from the WLC while trying to connect to make sure that is the case.
Also make sure that your client has certificate that is binded to a user account defined on your AD in away or another to have it working.

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:

EAP-TLS - 802.1x - Certificate renewal

Hello
I want to implement EAP-TLS as realised in Document "EAP-TLS under Unified Wireless Network with ACS 4.0 and Windows 2003". Everything thing works fine.
Though our customer wants to FW the Data WLAN/ VLAN and allow only data traffic between WLAN Client to a the terminal server within his secure LAN.
By blocking all other traffic(except Terminal Server sessions) we experienced that the MS WinXP Client cannot renew its` EAP_TLS Certificate (in this case both user and machine)when its` Time expires.
Could somebody give me a hint if there are other Cisco solutions for this issue.
I have also read something about Cisco Virtual office. Does this deployement coupe up to solve this issue?

The purpose Cisco ACS agent is, that ACS 4.x appliance (non-Windows2003 server) is capable to do Windows user authentication. I guess that won't help your issue.
What I don't get is the following:
Are you using WPA2(AES) as encryption? Then the WLAN is not considered as unsecure over the air.
The CA enrollment is a pure Windows issue. I haven't heard of Cisco mechanisms to cover that case. The only way I see is to open the FW for the needed MS services or to use another EAP-type (like PEAP).

EAP/TLS , PEAP problem on PORTEGE with WinXP sp2 Tablet ed.

We have: ap Cisco AiroNet350 with WPA-EAP, Freeradius with configured EAP/TLS and PEAP, tablet PC PORTEGE with WinXP sp2.
This problem discribed at http://wiki.freeradius.org/index.php/FAQ#PEAP_Doesn.27t_Work
Maybe to solve this problem we need a fix ( http://support.microsoft.com/kb/885453/en-us ), but microsoft support tells to contact with notebook manufacturer.
Can anybody help me with this problem?

Hmmm Im not expert on this field but it seems that the MS OS update is need. (I hope)
The preinstalled Windows OS is a simply OEM version and usually every updates should be possible. However, if the MS guys told you to contact the notebook manufacture so you can contact the Toshiba authorized service provider in your country for more details.
But I have investigated a little bit in the net and found this useful site:
http://searchnetworking.techtarget.com/originalContent/0,289142,sid7_gci945257,00.html
1. 802.1X depends on communication between your wireless router and a RADIUS authentication server. Whether you're using WPA2, WPA, or WEP with dynamic keys, the following 802.1X debugging hints can be helpful:
a. Re-enter the same RADIUS secret into your wireless router and RADIUS server.
b. Configure your RADIUS server to accept RADIUS request from your router's IP address.
c. Use ping to verify router-to-server reachability.
d. Watch LAN packet counts to verify that RADIUS requests and responses are flowing.
e. Use an Ethernet analyzer like Ethereal to watch RADIUS success/failure messages.
f. For XP SP2, turn on Wzctrace.log by entering "netsh ras set tracing * enabled"
2. If RADIUS is flowing but access requests are being rejected, you may have an 802.1X Extensible Authentication Protocol (EAP) mismatch or credential problem. Fixing this depends on EAP Type. For example, if your RADIUS server requires EAP-TLS, then select "Smart Card or other Certificate" on your wireless adapter's Network Properties / Authentication panel. If your RADIUS server requires PEAP, then select "Protected EAP" for the adapter. If your RADIUS server requires EAP-TTLS, then you'll need a third-party wireless client like AEGIS or Odyssey.
Make sure that EAP-specific properties match for your adapter and server, including server certificate Trusted Root Authority, server domain name (optional but must match when specified), and client authentication method (e.g., EAP-MSCHAPv2, EAP-GTC). When using PEAP, use the CHAP "Configure" panel to prevent Windows from automatically re-using your logon.

Possible to select self-signed certificate for client validation when connecting to VPN with EAP-TLS

In windows 8.2, I have a VPN connection configured with PPTP as the outer protocol and EAP : "Smart card or other certificate ..." as the inner protocol. Under properties, in the "When connecting" section I've selected "Use a certificate
on this computer" and un-checked "Use simple certificate selection".
My preference would be to use separate self-signed certificates for all clients rather than having a common root certificate that signed all of the individual client certificates. I've tried creating the self-signed certificate both with and without the
client authentication EKU specified, and I've added the certificate to the trusted root certificate authority store on the client. But when I attempt to connect to the VPN I can not get the self signed certificate to appear on the "Choose a certificate"
drop down.
Are self signed certificates supported for this use in EAP-TLS? If it makes a difference, I'm working with makecert (not working with a certificate server).
TIA,
-Rick

Hi Rick,
Thank you for your patience.
According to your description, would you please let me know what command you were using to make a self-signed certificate by tool makecert? I would like to try to reproduce this issue. Also based on my experience, please let me
know if the certificate has private key associated and be present in the local machine store. Hence, please move the certificate from the trusted root certificate authority store to personal store.
Best regards,
Steven Song

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

Use VPP. Select an MDM. Read the google doc below.

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!
