EAP-TLS and ACS 5.1 with AD

Hello,
I want to set up the ACS 5.1 for dot1x-Port authentication. I want to make a machine authentication against an AD-Domain and I got the following error Message:
24435 Machine Groups retrieval from Active Directory succeeded
24100 Some of the expected attributes are not found on the subject record. The default values, if configured, will be used for these attributes.
24483 Failed to retrieve the machine certificate from Active Directory.
22049 Binary comparison of certificates failed
22057 The advanced option that is configured for a failed authentication request is used.
22061 The 'Reject' advanced option is configured in case of a failed authentication request.
12507 EAP-TLS authentication failed
11504 Prepared EAP-Failure
11003 Returned RADIUS Access-Reject
What ist the problem? I can't find documents how to configure this in detail.
Can some one helf me?

Hi Torsten,
The option you are looking for is under system configuration:

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 am getting the following error for authentication:

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 match on custom EKU with ACS 5.5

Hi,
is there any possibility to match on a custom EKU with ACS 5.5?
I have to create a solution to limit access to a specific WLAN SSID. Only certificates containing a specific, self-created EKU should have access to this SSID. Other certificates from the same CA should be denied.
I know that it's possible with Microsoft NPS but I would prefer a solution with ACS. But in ACS the ceritifcate dictionary contains only a few attributes i.e. common name, issuer, subject, but not the Enhanced Key Usage (EKU).
Any suggestions?
Thanks,
Werner

Object Identifier Check for EAP-TLS Authentication
ACS can compare the OID against the Enhanced Key Usage (EKU) field in the user's certificate. ACS denies access if the OID and EKU do not match. For more information about options, see Authentication for profile_name Page, page 14-46.
When OID comparison is enabled and a valid OID string is entered, all the certificates that the users present for EAP-TLS authentication are checked against the OIDs entered. Authentication will be successful only if the OIDs match. If OID comparison is enabled but the user certificate presented does not contain any OID in the EKU field, authentication will fail.
To enable OID comparison you must:
•Enable EAP-TLS from the NAP page.
•Enter only contain numbers, dots, commas and spaces in the OID strings, for example: 1.3.6.1.5.5.7.3.2 is a valid OID string.
•Enter multiple OIDs as comma-separated values. For example: 1.3.6.1.5.5.7.3.1, 1.3.6.1.5.5.7.3.2 is a valid string.

EAP-TLS and MS AD auth problem

Hi,
I have a problem with an ACS to authenticate users with certificate on MS AD.
Working things:
PEAP authentication with the MS AD;
EAP-TLS authentication with the local DB.
Not working things:
EAP-TLS authentication with MS AD.
Because I'm able to auth users with PEAP on MS AD, I guess my config on MS AD is correct.
Because I'm able to auth users with certif in EAP-TLS, I guess my certif config is correct.
So, why it's not working with the combination EAP-TLS and MS AD.
I receive the error 'External DB Account Restriction'
Thanks for your help.

This issue is generally seens when there are multiple domains. Try out this step. Choose Network Connections from the control panel. Right-click the local area connection.Choose Properties. Double-click the TCP/IP option. Choose Advanced at the bottom. Click on DNS at the top. Choose Append these DNS suffixes. Add the FQDN for each domain that ACS authenticates against in the field.

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.

EAP-TLS and LEAP on a 1200 AP

Is it possible to have a 1200 AP use EAP-TLS and LEAP authentication simultaneously? We currently use LEAP in production and I have successfully configured a test 1200 AP to use EAP-TLS, but we would like to have it use both methods until all clients can be set up for EAP-TLS.

Authentication failed using EAP-TLS and CSSC against ACS

Hi.
Playing with a trial version of CSSC (Cisco secure services client) I had a problem that really I don´t understand.
Any 802.1x configuration work fine but when I use anything involving the use of certificates (EAP-TLS or PEAP using a certificate instead a password to autenticate) I always see the same log message in ACS:
"Authen session timed out: Challenge not provided by client" It seems that my client supplicant does not repond to the ACS when the first one proposed an EAP method.
First I discart a certificate error because the same certificate works fine with Intel Proset Wireless supplicant and Windows Zero Configuration. EAP Fast works fine using auto provisioning or manual provisioning.
Any idea? I red the CSSC administration guide but I did not find anything that explains this behaviour or defines the right configuration for this EAP method.
I´m using Windows XP SP3, Intel Wireless 4965AGN and CSSC 5.1.1.18; My CA is a Windows CA.ACS version 4.2
Thanks in advanced.
Best regards.

Today is not mmy day.
It´s still failing and maybe I will open a TAC case.
I´m looking at the log file of the CSSC and I don´t like what I have seen.

It seems that It found a valid certificate, starts the Authentication proccess and when it must request the ACS challenge it fails when loading the private key and crash the supplicant
Do you think the same??

802.1x with EAP-TLS and dACLs

Hi,
i'm looking to enable 802.1x on the wired network using EAP-TLS. The radius server will be an ACS5.2 running on the appliance. We'd also need some authorization for different machines - we'd like to use dACLs for that so that machine A will get full access while machine B will get restricted access (both client machines are related to different business units). So machine based auth (clients run XP SP3 or Vista).
I'm not very clear about the following...based on the presented client machine certificate, we should be able to apply an authorization policy (dACL). How can we set this up...anyone else tried this before?
in 'worst' case we could do machine auth (EAP-TLS) to validate it's a corporate machine connecting, followed by user authentication & authorization (EAP-PEAP) to apply access policies based on the user id..with PEAP is see it might be easier to extract user info out of AD to make policy decision...?
Thanks,
Guy

Hi Guy,
provided that the dACL is just part of the Authorization profile that you return to the client, you need to make sure that you have the correct attributes so to allow the authorization policy evaluation.
In ACS 5 when you configure a "Certificate Authentication Profile", the basic option is just to validate the client certificate.
So as long as ACS can validate the cert using the trusted CA certificates installed on ACS, the authentication is successful.
However, if you do so the only attributes you can base your authorization policy evaluation are the non-binary attributes of the certificate itself, as there's no query done to any backend DB in this case.
If you want to evaluate the authorization policy where you want to check for additional attributes that are stored on an external DB (e.g. Active Directory), you can do it in two ways:
1) enable certificate binary comparison on the "Certificate Authentication Profile": this will both perform the binary comparison of the cert and it will fetch the user attributes from AD; this of course requires that the certificate for the user is also stored on the "userCertificate" attribute in Active Directory.
2) configure an "Indentity Store Sequence" where you select:
- Authentication Method List : Certificate based : "Certificate Authentication Profile"
- Additional Attribute Retrieval Search List : Add "AD1" among the selected Identity Stores
In this case ACS won't perform binary comparison of the cert, but it will look for the corresponding user account in AD so to fetch additional attributes (group membership, etc..)
You can find relevant documentation about this on the ACS user guide:
- Configuring "Certificate Authentication Profile"
http://www.cisco.com/en/US/customer/docs/net_mgmt/cisco_secure_access_control_system/5.2/user/guide/users_id_stores.html#wp1054057

- Managing policy elements:

I hope this helps.

'Could not find user' with EAP-TLS in ACS

Hi all,
we are running ACS 4.2(1) Build 15 on a Win2003 member server and use the ACS for EAP-TLS with certificates (Microsoft-PKI) for WLAN authentication (WLC 4402, 6.0 and 4.2). We are using both machine and user authentication.
Sometimes machine authentications fail with following message in AUTH.log:
AUTH 11/01/2010 09:11:28 E 1395 1904 0x31cb External DB [NTAuthenDLL.dll]: Could not find user host/<xxxxxxxx>.com (0x5012)
But some minutes/hours later the same machine can authenticate successful. Other machines never have this problem, no problems at all with user authentications.
Does anyone have an idea where I can proceed with troubleshooting? I haven't found any related messages in server event logs. Are there any other logs where I can find reasons for these problems that are occuring only sometimes?
Thanks
Kai

AUTH.log and RDS.log are two log file you need to look into on ACS side. Make sure the log level is set to "Full"
You might need to check the log on AD side to see why it could not find this host.
Comparing the logs between the working and non-working cases might be helpful.

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.

EAP-TLS on ACS v4 for wireless users

Hi,
I?m trying to deploy EAP-TLS authentication method on ACS v4.0 for my local wireless users; really I stuck with the certificate issue and need your assistance to understand the required procedures to accomplish the task.
As mentioned on the ACS configuration guide I have to have CA server to generate certificates for both ACS and wireless users, but I found an option on the ACS under System configuration tab then ACS Certificate Setup a Generate Self-Signed Certificate, I generated a certificate and uploaded a copy to my PC, installed and followed the recommended steps to configure the Microsoft XP client configuration but still I got the error ?Windows was unable to find a certificate to log you on to the network SSID? . Honestly I don?t know if this is possible but I gave it a try but failed.
Kindly advice what is the appropriate and easiest way to accomplish the task, if you could provide me with helpful documents I?ll appreciate it.

FlexConnect, EAP-TLS and dynamic VLAN assignments

I need to integrate Cisco ISE and WLC5508 with FlexConnect (local switching) using EAP-TLS security for wireless clients across multiple floors (dynamic VLAN assignments based on floor level). The AP model used is 3602.
I have some questions:
- What RADIUS Attribute can be used for dynamic VLAN assignments based on floor level? Is there an option where I can group all LWAPs in same floor for getting certain VLAN from ISE?
- I intend to use WLC software version 7.2 since 7.3 is latest version. Has someone use WLC software version 7.3 without any major bugs/issues pertaining to FlexConnect and EAP-TLS?
- I read some documents saying L3 roaminig is where the associated WLC has changed. However if user move to different subnet but still associated to the same WLC, would this be consider as L3 roaming too?
Can someone assist to clear my confusion here? any reference url for layer 2 and layer 3 roaming details is appreciated. Thanks

I'll give this a shot:)
For radius vlan attributes, bothe ACS and ISE in the policies have the ability to just enter the vlan id in the profile. You can either do that or use the IETF attributes.
The RADIUS attributes to configure for VLAN assignment are IETF RADIUS attributes 64, 65, and 81, which control VLAN assignment of users and groups. See RFC 2868 for more information.
64 (Tunnel-Type) should be set to VLAN (Integer = 13)
65 (Tunnel-Medium-Type) should be set to 802 (Integer = 6)
81 (Tunnel-Private-Group-ID) should be set to the VLAN number. This can also be set to VLAN name if using a Cisco IOS device (excludes Aironet and Wireless Controllers however).
You can find this by searching on Google.... A lot of examples out there
v7.2 and v7.3 I have had no issues with, with any type of encryption used. With 7.0 and 7.2, I would use the latest due to the Windows 8 fix.
Layer 3 roaming is what's going to happen if the AP's are in local mode. This means that the client will keep their IP address no matter what ap they are connected to and or WLC as long as the mobility group is the same. So a user who boots up in floor 1 will keep its IP address even if he or she roams to the 12th floor and as long as he or she didn't loose wireless connection.
FlexConnect you can do that. The AP's are trunked and need to have the vlans. So what your trying to do will be disruptive to clients. When the roam to another floor ap that is FlexConnect locally switched, they will drop and have to re-associate in order to get a new IP address.
Hope this helps.

EAP-TLS and getting a new user to log in on a wireless network

I have setup EAP-TLS using AP1232 + ACS + CA + Active Directory + some wireless client machines. Works fine.
My issue is when I have a new user, who has never logged onto the client workstation. I know that if I attach the workstation to a wired network and have the user login, request a cert, issue it, and install it, the wireless will work once I have the wired connection disabled and wireless enabled. However, that kinda defeats the purpose of a WLAN.
How can I get my new users in? After all, getting associated to the AP depends on the user cert, which depends on the ability to get to the network in the first place to request/install a cert.
After further reading and research, I believe that my delima will be fixed by configuring EAP-TLS Machine Authentication. What I'd like to know is whether the CA in this scenario MUST be an Enterprise Root CA or can it be a Standalone CA?

check the below link and read server requirements.

The stanalone ca needs to be trusted by AD

What windows are you using? The default behaviour of windows is it do user authentication.You would need to play with registry to make systems to do only machine authentication.
You would need connectivity when you want install the ca certificate, or else allow open authentication on the access point to have the connectivity and once the certificates are installed disable it.

EAP-TLS and multiple ADs

I have a customer with multiple Microsoft ADs.
And I need to get EAP-TLS working for client in all ADs.
Each AD has it's own CA.
We will do machine authentication.
We have a Cisco Secure ACS server to handle the authentication.
My question: Is it possible to have the ACS authenticate clients with certificates from various ADs/CAs?
Best regards
Kennet Grau

Are these different AD domains belong to the same forest or diffent? Is there any trust relationship among them?

ISE 1.2 EAP-TLS and AD authentication

Hi,
I am sure I have had this working but Just cant get it to now.
So I have a Computer that has a Certificate on it with the SAN - princible name = to [email protected] This is an auo enroled Cert from my AD.
My Authentication profile says
IF the SSID (called-station) contianes eduroam and Princible name containes @mydomain.com then user a certification authentication profile. (see attachemnt below)
Then my authorization profile says
if active directoy group = "Domian computers" then allow access.
When my computer trys to join it passes the certificate test, but when it gets to the AD group is get the below.
24433          Looking up machine in Active Directory - [email protected]
24492          Machine authentication against Active Directory has failed
22059          The advanced option that is configured for process failure is used
22062          The 'Drop' advanced option is configured in case of a failed authentication request
But I know my machine is in AD? What do i need to do to get the PC to use EAP-TLS to authenicate and AD group to authorize?
Cheers

This accepts all requsts to one SSID and then as you can see if it is EAP TLS uses Cert store (see below), other wise AH
This jsut says if AD Group = /user/domainComputer allow full access (simple rule)
