LEAP EAP-TLS on WLC

Hi,
I need to deploy certificate based authentication for some Intermec client devices for a customer. I am planning to use a separate SSID for this. There are other already existing SSID's which have radius based authentication.
question : if i dont select any radius server for this eap tls ssid and select only 'LEAP' , will it work ? Or will the WLC still search for the already defined radius servers and fail authentication ?
question2 : if above is not possible, i will have to go for eap tls with ACS . anybody has got easy steps to get eap tls up and running ? (LAP 1252, wlc 4400, acs 4.1, windows CA )
regards
Joe

wireless wlc,
The WLC side and the radius side is basically setup the same as you would for PEAP. The only difference is if your policy you create in the radius specifies a certain eap type. If not, then you don't have to worry about that. The main thing is that you have a valid computer cert and users cert. You can verify this by the device wireless profile and on Windows 7 you select user authentication or computer authentication. If one works and the other doesn't, then you knop which cert is missing. Selecting user and computer will check for both. Vlaidat server certificate should only be cheked if the CA is in the Trusted Server Certificate Store. The CA must be trusted on the domain controller and the IAS, NPS server also.

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

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.

Hi, anyone experienced issue like this?
I am installing a WLC 5508 using EAP-TLS authentication with an IAS Radius server.
I got “Access-Accept” debug message received from RADIUS server.
However the wireless client failed to connect.
Below is partially the debug message from the WLC
Any feedbacks are welcome

EAP-TLS with WLC 5.2.178 Improve Performance and Roams?

Good Morning...
I've been working on moving our clients over to EAP-TLS with Machine Auth for sometime. I had moved the IT Department over a couple of months ago as a test with no issues reported and have tested on a few of our Medical Carts (CoWs) as well with no issues reported. However, upon deploying to a larger population of Carts (Specifically using Atheros 5006x 7.x Driver {No Client}) I've been getting some client drop complaints. If I look at the client history I do see a lot of "Client Associations" or Roams that occure anywhere from ever 2minutes, to every 10minutes to every 5 hours. These carts do move around ALOT as they are pushed from one Patient Room to another so I'm guessing the drops are occuring during a re-authentication phase as the device roams. Looking at the device you might not be able to tell it's dropping but the software we use (Meditech) is very connection sensitive in doing a simple ping you may see a couple of dropped packets until the client is fully connected again. So I'm guessing the roaming is the issue. What can we do to fight this or make it more effecient? It was mentioned to me by a colleague (who doesn't know where he saw it) that he thought it was possible to configure the WLC's to not reauthenticate on the roam? I'm guessing something must be able to be tweaked if the 7921's and 25's support EAP-TLS as this type of latency would never work. By the way I'm using an ACS 4.2 as my authentication platform mapped back to AD.

You will always reauth with a roam. That is part of the 802.11 spec. How you reauth will depend on the type of security you have setup. If you are using WPA2/AES or CCKM the reauths can be done with a PMK instead of needing to go through the entire reauthentication process. Try running "debug client " for a client having the issue and see if it gives you an idea of where the authentication is failing.

EAP-TLS Questions....

Hi all,
My setup is like this..
Laptop - LWAPP - WLC - ACS - AD
I m using CA to generate certificate.. I have configured EAP-TLS on WLC & ACS SE. Everything is working fine ie when i issue a certificate from CA on my AD login name & install that certificate i m able to connect to WLAN.. For security on WLC i have enable WPA & 802.1x...
What i want is that when i boot up the laptop it should directly get connected to Wireless network & whne i try to login using my user name & password it should prompt for if my password is expired or something & get connected to AD. But this is not happening which use to happen when we were using peap as it ask for username & paswword to connect but not in case of EAP_TLS it only check for valid certificates....
Thanks in advance..
regards,
piyush

Hi Fella,
i had one more issue ie want to do perform machine authentication as the laptops boot up along with the user authentication hen the users logs in.
I had set AuthMode value to 1 for it. But how should i check on my ACS SE that the machine is authenticated or not & is it possible that during login using username & password the WLAN should get connected as it is for ethernet LAN.
Thanks for ur reply..

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 ;)

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.

ISE 1.2 / WLC 5508 EAP-TLS expired certificate error, but wireless still working

Hi I have a customer that we've deployed ISE 1.2 and WLC 5508s at. Customer is using EAP-TLS with and everything appears to setup properly. Users are able to login to the network and authenticate, however, frequently, I'm getting the following error in ISE authentication logs:
12516 EAP-TLS failed SSL/TLS handshake because of an expired certificate in the client certificates chain
OpenSSL messages are:
SSL alert: code=Ox22D=557 : source=local ; type=fatal : message="X509

I'm not sure if this is cosmetic or if this is something that I should be tracking down. System isn't in full production yet, but every client seems to be working and there is no expired cert in the chain. Any ideas what to check?

Hello Dino,
thanks very much for your reply.
The client uses a machine-certificate, the PKI is not a microsoft one, but a third party PKI. The certificate is fresh and valid, the root-cert is installed and checked to be validated against it for the login.
Clock is correct too. The same setup works flawlessly in Windows 7 and XP.
EKU is set on the certificate (1.3.6.1.5.5.7.3.2)
I suspect the cert-setup itself, but don't get a clue where this might stuck...

EAP-TLS with ISE 1.1.2 and WLC 7.0.228

Hi,
I'm on process of implement Cisco ISE with Wireless LAN Controller. According to my post, I would like to know that if Supplicant Provisioning and EAP-TLS does support on this type of firmware code.
WLC running on 7.0.228 since most of production APs are 1230
ISE running on the latest version.
I have to use EAP-TLS and Supplicant Provisioning on these platforms.
Is this possible to do about this ?
Thanks,

WLC 5508 - EAP-TLS - Windows 8.1 Third Party PKI

Hello,
Does anybody know what could prevent a Windows 8/8.1 system to connect to a WLC via EAP-TLS? Windows 7/XP do not have any problems here.The radius server accepts the request, but WIndows 8 still tries to authenticate.
Software is updated to 7.6.120.0, I tried to setup timeout values, but no success at all.
Did anyone have similar problems with Windows 8/81?

WLC EAP-TLS

Hi,
My Wireless network consists of 8 WLC and 2 Cisco ACS 1113 with 4.2. I need to implement certificate authentication for Cisco Wireless Phone SSID. I tried PEAP along with certificate generated by Microsoft Cert Server, but the issue is the client can ignore the certificate and I believe only way to force is via Active Directory group policy.
So as my Cisco IP Phones are not joined to Active Directory I think the only option is to use EAP-TLS. For this I have the following Queries.
•1.     What will be the SSID security setting. ( I tried Layer 2 802.X with WEP 104bit encryption)
•2.     Do I need to install any certificate on WLC if yes which Certificate (Ex root, Client)
•3.     What Certificate should be installed on Client.
•4.     What should be the client PC security setting for EAP-TLS
I had gone through the following Docs for reference.

Cisco 5508-WLC using MS NPS as RADIUS Server for EAP-TLS

Has anyone experienced a problem getting a Cisco WLC to work with MS NPS server? We've done it before albeit with differnt code versions.
I have a Cisco 5508 WLC running 7.0.116.0 code hosting a WLAN configured for WPA2 with 802.1x for authentication. I have two Windows NPS servers configured as the RADIUS servers for EAP-TLS authentication. Via debug info on the WLC I can see the 802.1x handshake take place with the wireless client and the WLC as well as a successful transmission of an Authentication Packet from the WLC to one of the RADIUS servers. However on the WLC I see repeated RADIUS server x.x.x.x:1812 deactivated in global list and on the NPS server I'm seeing event log errors indicating "The Network Policy Server discarded the request for a user" along with the pertinent auth request info that I would expect the NPS server to receive from the WLC.
Based on the WLC debug info I'm never actually getting to the EAP-TLS certificate authentication part. It seems the NPS servers don't like the format of the initial RADIUS authentication request coming from the WLC and so don't respond whcih in turn casues to WLC to switch to the other NPS server which produces the same issue.
Any ideas of what might be the issue or misconfiguration?

Jim,
I wanted to know if you can setup wireshark on both of the boxes and see if your are hitting the following bug:
http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCti91044
It looks as if the WLC is retransmitting the client traffic from one radius session with primary over to the secondary in which the radius state attribute that was assigned from the primary server is probably hitting the secondary server. Therefore if the state attribute isnt assigned from the secondary server it will discard the packet.
May need to open a TAC case to see if this issue is on the 550x controllers also.
Thanks,
Tarik

WLC 4400: EAP-TLS

Good day!
I tried to set up the EAP-TLS according to
- http://cciew.wordpress.com/2010/06/10/eap-tls-on-the-wlc/
- http://www.cisco.com/en/US/products/ps6366/products_configuration_example09186a0080a77592.shtml
- Jeremy video about EAP-TLS
The main question is about certificates.
Tell me if I am wrong - There are two types of certificates that we need to upload to the WLC:
1) Device certificate - this is quite clear, OpenSSL, Certificate Request and e.t.c.
2) CA Root certificate - if there is only one CA Root than clear, but if we have the following chain
Root CA -> Intermediate CA -> WLC
a) Do we need to upload the whole chain "Root CA -> Intermediate CA" to the WLC ?
b) If yes, what format is it going to be? maybe smth like this
------BEGIN CERTIFICATE------
*Intermediate CA cert *
------END CERTIFICATE--------
------BEGIN CERTIFICATE------
*Root CA cert *
------END CERTIFICATE------

Nicolas, thank you for your reply!
1)
I've already seen the article, but now notice some interesting fact:
"Note: Chained certificates are supported for web authentication only; they are not supported for the management certificate."
Regarding this note, do we need to bundle any certificates for EAP-TLS scheme?
2)
On the WLC we have an opportunity to download two types of Certificates:
- Vendor Device Certificate - it is made of CSR request and then uploaded to the WLC in .pem format
- Vendor CA Certificate - this is more interesting:
Yesterday I bundled Root and Intermediate CA Certificates in one .pem file, then uploaded it to the WLC as "Vendor CA Certificate" - the result was suсcessful! During the EAP-TLS auth process SSL Handshake completed sucessfully and I connected to my EAP WLAN!
In the controller Client Properties I saw the EAP TLS>
Everything seems to be ok, strange...
May be, the chain of Root and Intermediate CA Certificates is the redundant information, but the scheme seems to be working!

Is roaming transparent to users when authenticating with LEAP or EAP-TLS?

We are planning the installation of a number of Access Points with LEAP authentication to ACS. We want to know upfront whether the users have to reautenticate everytime they roam from one Access Point to another. Is it the same with EAP-TLS or EAP-TTLS?

Your users will have to re-authenticate to each AP but it happens automaticaly throught the client. IF all of your APs are on the same segment/subnet you shouldn't have a problem.

WLC configuration for EAP-TLS

Hi,
I am tring to set up a Cisco WLC 2006 with EAP-TLS + WPA.
Everytime I try to log in to the network my wireless card gives a message saying " validating user", but nothing else happens.
I cannot find any manual for configuring this. Can anyone perhaps assist?
Regards
Dean

More details would be helpful:
What RADIUS server are you using, what CA are you using, where (what VLAN) they located, which port of the WLC are you connected to (RADIUS/CA)?
Are you using the Vendor's client software or MS wireless zero config? Which version? or Linux? Which distribution/version?
Having this info will be a good start ...
Let us know

WLC Local EAP-TLS auth, certificate ACL feature?

Hi All,
I implemented local EAP-TLS authentication according to http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a0080851b42.shtml. All is working fine, clients - Wi-Fi bar code scanners, WLC -2x4402, SV - 7.0.116.0 Certificates generated by Enterprise CA.
Afterwards, I discovered that certificates cannot be filtered by cname, or user name on WLC. It means that ANY certificate issued by CA will be authenticated against my WLAN. CA issues a whole lot of certificates (RRAS VPNs, WEB clients, etc. ) I want to filter access for my wireless clients using local EAP solution (WLC are at remote location). Can I accomplish it without external RADIUS server? Something like IOS certificate ACL?
Thanks in advance.

Thanks Nicolas, sad but true, I failed to find any possibilites at WLC.
It seems I need to configure external RADIUS and use local EAP only in case of WAN failure.
