• Wrong with EAP - TLS with Wireless before Windows logon

  Evil begins with a list of equipment;

  5508 WLC

  3502i AP

  Cisco ACS 5.3

  Clients Windows 7

  WLAN is set up with WPA2 AES with 802. 1 x for key management.

  Customer is set up with WPA2/AES, authentication method is Microsoft: card chip or other certificate on the computer. Authentication mode authentication is the user or computer.  The client is configured to use a certificate on the computer.  "It only works if the authenticating user or computer is seected."  If I use computer authenticate option... it says that it cannot find a certificate to use for the EAP.

  ACS is configured to allow only for the EAP - TLS protocol.

  We have created a stand-alone CA server and distributed CA certificates root and client authentication for all test systems.

  This whole process with EAP - TLS works very well if you are already connected to the machine, with the credentials of the cache.  Once I disconnect the Windows 7 client, I lose the connection to the WLAN.  We want to stay connected to the WIFI network.  W PEAP / MSCHAPV2 works very well with stay connected to the WLAN, but we want to use EAP - TLS.

  Any ideas?

  Thanks in advance,

  Hi Ryan,

  You actually answer your own question :) The reason for the fault is because the computer account doesn't have a certificate, so when your computer account user cannot connect to maintain the session going, and so you are disconnected. Provide the computer with a certificate account and your problem will be solved.

• Expired password AD with EAP - TLS

  Hello

  It's probably a stupid question but this is. I have LWAPPs a WLC with ACS using EAP - TLS with a backend ActiveDirectory. I connect a laptop to the network with a wired connection and the connection to the domain. The cert of the user is then pushed to the laptop by group plicies or something else.

  Now, I can disconnect from the cable network and reboot the laptop. Connection to the laptop is via the credentials cached and it authenticates on the wireless network using EAP - TLS, well.

  The quiestion is is it a mechanism in this configuration for againg password the passowrd AD user that is used to connect to the Windows profile in the first place. It is necessary to reconnect to the network wired to do this or allow a change passowrd more once that the password years wireless?

  Thank you

  Pat

  With eap - tls, your wireless connection is insensitive to the user password. If the user will be able to change his windows password without having no problem with the wireless I know

• WiFi with EAP - TLS works on the Xoom?

  Did anyone had success with using the Wifi requiring user certificates? I try to get my Xoom to connect to the corporate network (EAP - TLS) and followed the instructions for the IPad and imported my homologated in Android correctly. But when I connect, it hangs to the connection state minutes before finally giving up.

• Problem with EAP - TLS EHT begging Provisioning

  Hi all

  I have a demo built using ISE v1.1.3 patch 1 and a WLC by using the v7.4.100.0 software.  The purpose of the demo is available to begging a device with an EAP - TLS certificate...  'device on-boarding.

  The entire CWA / registration of the device, everything is perfect and works well.  I use a Cert publicly signed on ISE built from [Root CA + intermediate CA + host Cert] which is used for HTTPS and EAP and I also PRACTICE operating against my Win 2 k 8 Enterprise Edition CA that belongs to my Active Directory.  It all works very well.

  The problem is that when ISE push the WIFI config to the device, it tells the Client to check for the root CA, but RADIUS within the ISE processes are related to the intermediate CA.  This leads to a problem where the Client does not trust the certificate of the ISE.  It doesn't seem to be a way to configure this behavior within the ISE.

  If anyone else has experienced this? Know a solution? Suggestions for a workaround?

  See you soon,.

  Richard

  PS - also using WinSPWizard 1.0.0.28

  Hi Richard,

  It is a bad behavior ISE is commissioning intermediate CA in similar BYOD of scenarios (hierarchical certification authority) registration process. It'll be fixed soon. The genius is almost ready with the fix.

• 4.2 of the ACS and EAP - TLS with AD and prefix problem

  Hello

  We have the following situation:

  -2 X ACS (ACS SE 4.2 1 x and 1 x 4.2 ACS) for domain

  -2 x ACS (ACS SE 4.2 1 x and 1 x 4.2 ACS) for domain b.

  First of all, there is a problem to have an ACS SE and a CBS work together for an area, I do not? When we haven't had that one area and the two SE ACS were responsible for domain A, it worked.

  Now after the changes, authentication of machine with EAP - TLS is no longer in effect. In the newspapers, it always says that "external user DB is unknown" for a username (machine) as host/abc.domain.ch

  This is the normal output of the Remote Agent, he finds the host but then nothing happens:

  It is clear that the test failed because of the bad 'past to a computer' but it's a different output as before. I saw that in ACS 4.1, you can change the prefix of send_break_action for nothing, but in 4.2 it is no longer possible.

  This could be the problem, or if someone sees no other problem?

• Machine based authentication using EAP - TLS, MS CA and 5.2 of the ACS

  I use ACS 4.2 for Windows for a couple of years now and I'm pretty comfortable with it.  5.2 model is much more different than what I expected.  We downloaded the trial in our laboratory for 90 days, and I try to get 802. 1 x wired works so we can be sure that we want to buy it.  I've looked everywhere and I have been unable to find some basic instructions on how to configure the following in a step by step process scenario:

  1. integrated AD

  2 EAP - TLS

  3 certificates

  4 Microsoft CA

  5. the applicant is XP SP 3

  6 non-Cisco 802.1 x compatible switches (switches are not the question)

  I got GANYMEDE to work fairly easily, but I am confident the issues I have are user based :).  Does anyone know of a doc somewhere that goes on a scenario like this (in addition to the user manual and docs of migration ISBN)?  Also, we have the assurance of software on our box 4.2 - TAC support questions we have on the 5.2 box while we are it do demonstrations?

  Thanks in advance.

  Hello, Christopher.

  I'll try to give you some tips to achieve what you want.

  Additional info can be found in the user guide:

  http://www.Cisco.com/en/us/docs/net_mgmt/cisco_secure_access_control_system/5.2/user/guide/acsuserguide.html

  1. in the identity store / Active directory, check "enable machine authentication.

  2 import a certificate for ACS

  Go to System Administration > Configuration > Local Server Certificates > Local certificates and click the Add button.

  Select how you want to import the certificate, and then verify the Protocol EAP

  3. Add your switches as aaa clients

  Access network resources > network hardware and the AAA Clients, click on create and add configure address IP + shared secret for the RADIUS.

  4-go to access policies > Access Services and click on create a new access service.

  Select the selected Type of Service and network access in the list.

  Verify the identity, group mapping and authorization

  5 - go to the access policies > rules of selection and select "Rule based selection result" if not already done, then click Customize at the bottom right of the screen, and then add the properties that allows you to match your device with which you want to do TLS.

  You can use the IP address of devices, or you can create a NDG (in network resources), assign devices to the NDG and match this NDG in your rule.

  If all your switches RADIUS will make eap - tls, you can change the rule

  Rule-1

  Ray game

  Default network access

  While in the result, you choose your service of access created in step 3.

  6 - go to the access policies and click on the access service that you created in step 3. In the allowed Protocols tab, see EAP - TLS

  7. unfold your access service menu, and then click identity. Select your ad as being the source of the identity

  8. check that the 'Allowed access' rule is selected in the authorization to access your service

  These measures define your devices, and then create a rule to say that ACS must use an individual service for this access devices and set this access service to use AD as authentication.

  Again, what are the basic steps, he may miss some things to do depending on your configuration, but I hope this will help you.

  ACS 5 may be difficult at first, but once you get your hands on it, you will see that it is powerful.

• [Cisco ACS 5.2] EAP - TLS authentication failure

  What we are e

  Hello

  I set up a WiFi connection on Windows XP and Windows 7 with EAP - TLS (using Cisco WLC 7.0.235.3 and Cisco ACS 5.2.0.26.10). It is configured with the authentication of the computer and computer certificates are automatically registered for Microsoft PKI.

  It works well!

  Now, I configured Windows 8 with the same configuration.

  First authentication works, but if I manually disconnect and reconnect, I got this error on ACS: 22047 username main attribute is missing from the client certificate

  In the EAP packets, we could see that Windows 8 sent a TLS session but ticket session has not properly taken over by ACS...

  Configuration of the ACS, we checked the option "enable EAP - TLS Session resume' with the session timeout"7200 ".

  I found this bug

  http://Tools.Cisco.com/support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId= CSCtn26538& from = summary

  It seems to be my problem but the reboot does not work in my case...

  It is set at 5.3 (0.40.2).

  I plan to install version 5.4.

  Do you know if this fix is supported by 5.4?

  Thanks for your help,

  Hi Patrick,

  What is set in point 5.3 must be set in point 5.4.

  Even if the same issue appeared with 5.4 there an ID different bug and identified as an independent issue (with different causes, usually)

• PEAP EAP/TLS, PORTEGE with WinXP sp2 Tablet Edition problem

  We have: Rev AiroNet350 Cisco with WPA - EAP: Freeradius with EAP/TLS and PEAP, tablet PC PORTEGE with WinXP sp2 configuration.

  This problem discribed in http://wiki.freeradius.org/index.php/FAQ#PEAP_Doesn.27t_Work
  Perhaps to solve this problem we need a fix (http://support.microsoft.com/kb/885453/en-us), but microsoft support said to contact the laptop manufacturer.
  Can someone help me with this problem?

  Hmmm I m not an expert in this area, but it seems that the MS OS update is necessary. (I hope)
  The preinstalled Windows operating system is a simple OEM version and generally all updates should be possible. However, if MS guys told you to communicate with the manufacture of the laptop, you can contact the maintainer authorized Toshiba in your country for details.

  But I studied a bit on the net and found this site useful:

  1. 802. 1 X is based on communication between your router and a RADIUS authentication server. If you use WEP, WPA or WPA2 with dynamic keys, 802. 1 X debugging following tips may be useful:
  a. reintroduce the same RADIUS secret in your wireless router and the RADIUS server.
  b. configure your RADIUS server to accept the request of the RADIUS of the IP address of your router.
  c. use ping to check the accessibility of router-server.
  d. package watch LAN account to verify that RADIUS and answers queries are fluid.
  e. use an Analyzer like Ethereal Ethernet to watch RADIUS success/failure messages.
  f. for XP SP2, turn on Wzctrace.log by typing "command netsh ras set followed * activated.

  2 if RADIUS is flowing but are rejected requests for access, you may have a problem of incompatibility or credential X Extensible Authentication Protocol (EAP) 802.1. This setting depends on Type EAP. For example, if your RADIUS server requires EAP - TLS, then select 'Card chip or other certificate' of your adapter wireless network properties / authentication Panel. If your RADIUS server requires PEAP, then select "Protected EAP" of the adapter. If your RADIUS server requires EAP-TTLS, then you will need a third-party wireless like AEGIS or in Odyssey client.
  Make sure that this specific EAP properties match for your adapter and the server, including the server CA certificate root trust Server domain name (optional but must match when it is specified) and the customer (EAP-MSCHAPv2, EAP - GTC) authentication method. When you use PEAP, use the control panel to 'Configure' CHAP to prevent Windows from automatically re-use of your connection.

• Novell NDS CA and EAP - TLS

  Hi all

  I configured an ACS Server 4.1 with Novell CA authentication certificate. internal to the ACS server works very well and the group maps also works without problems.

  Now, the customer wants to use eap - tls in the wlan configuration. Authentication with user name and password works fine. If I activate the validate the certificate of the server in the windows xp wireless configuration settings, that I do not have access to the network. I get an error message on the client and in the journal of the CSA, I see an error with eap - tls ssl handshake!

  Are there problems with certificates of AC novell and novell?

  Any ideas?

• EAP - TLS uses WEP?

  Why do you need to configure WEP as a data encryption when you use EAP - TLS?

  'Ensure that the data encryption is set to WEP.

  You cannot use WPA2?

  Gr.

  Remco

  Remco,

  1. what should I do to configure EAP - TLS?

  In order to configure EAP - TLS, the only configuration on the WLC is selection of 802. 1 x 2 layer security screen.

  2. users must have a certificate of the user and computers need a computer certificate. IAS server needs a server certificate.

  You RADIUS server must have a certificate and this must be added to the list of trusted certificates on each client. There is no configuration required on the side of the controller for this.

  3. I want to use WPA/PWA2 enterprise with AES encryption. In all the documents, you can see that the client is configured with WEP.

  By default, if you choose 801.x on layer 2 security, WEp is used as the encryption. You must understand that these are two different things. One is the encryption (TKIP/AES and the other is the 801.x authentication). So if you want to use WPA2 with EAP - TLS, you must select WPA1 + WPA2 as layer 2 security, then 802. 1 x on the same screen in "Auth key Mgmt" select 802. 1 x

  Let me know if that answers your question.

• Does anyone know if the version of Cisco Clean Access Server supports the 4.1 (8) SHA - 256 signed SSL certificates?

  Yes, I know they are very old servers and technically, we should move away from CASES in total. But unfortunately, it's an environment I inherited, and I am now dealing with issues.  Because of the requirement to move away from sha - 1 signed certificates that I need to replace my existing certs, certs signature sha-256.  But before I do that I would like to know if anyone knows if CASE version 4.1 (8) supports SHA - 256 certificates?  I did check the release notes, but there is no mention of the supported versions of SHA, etc..  I tried TACS but no joy there either, etc..

  Hello Rafael,.

  SHA - 2 signed the certificate of support was added in 4.7.2 for SCS and CAM.

  We have filed a default document to have it documented in the release notes.
  CSCud99946    Note of support for the NAC should say we support certs of SHA - 2

• ISE 1.4 using EAP - TLS can´t identify user in an ad group

  Hello

  I have a client who wishes to use the EAP - TLS on his Wifi authentication and he wants users in a separate AD Group for the SSID to cooperate.

  I found the solution of operation or with PEAP with EAP - TLS authentication, it does that without the policy of 'ad group.

  Any idea on what I can do to get it to work?

  George

  I found the problem, I had to adapt the 'certificate of authentication Profile' for the AD client

  What made your dot1x in your PC configuration? How the ISE journal watch, when it works?

• ISE: advise users that EAP - TLS can only be used

  A large School Board accepts only EAP - TLS connections.  This requirement is easily disseminated to teachers, but not students whose personal devices continue to try to connect using the PEAP Protocol.   Once users connect with EAP - TLS, they are authenticated on AD.

  1 can we through the switch block PEAP but leave the EAP - TLS to cross? I could not find a command for it.

  2. If we cannot stop the PEAP requests to ISE, could treat us like CWA PEAP connections, but have a special authorization rule that would say If inner PEAP tunnel is then the CWA-nonEAP-TLS do web authentication that would be a custom web page which would have a message instructing students how to use EAP - TLS? This would make sense?

  3. do you have better suggestion how to block before PEAP that it reaches EHT or a way using ISE to indicate to users that they should use EAP - TLS, PEAP not if they want to connect?

  Thank you.

  Cath.

  Usually at the start of the eap negotiation, there is an agreement between the applicant and the radius server on which eap types are negotiated. If you have that suggested the client to eap - tls and the supplicant is misconfigured and uses the PEAP Protocol, he must drop off.

  You can consider a strict exclusion policies so that if a customer fails to authenticate after 3 attempts you can exclude them for a few minutes.

  You can create a homepage (url redirection) that when type mschapv2 authentication and the authentication status set to 'failed' a self-help html page is presented to the end user to use eap - tls, keep in mind that port and ip will authorized in forwarding ACL.

  What do you see in the failed attempts?

  Thank you

• 802. 1 x EAP - TLS for wired users with ACS 5.5

  Hi all

  We are setting up a new configuration for wired users authentication with 802.1 x (EAP - TLS). ACS 5.5 we use as an authentication server.

  We have added the certificate (internal) CA root and certifcate for ACS signed by CA. Now, we want to check that authentication works or not. I hope that the CA root and identity certifcate also we need to install in laptop computers. But I don't know how to download the certifcates for client machine manually to CA.

  Please suggest on how to get certificates for clients both manually and automatically?

  Thank you

  Vijay

  Hi Vijay,

  for Wired 802.1 x (EAP - TLS) you must have the following certificates:

  Intermediate server on ACS - Root CA, CA certificate,

  The customer - Root CA, intermediate CA, user certificate (in the case of user authentication) or Machine certificae (in the case of authentication of the computer)

  I do not know what third-party certificate you use, if its Microsoft in the House or any other certificate server, you need to download the client certificate to the server itself.

  In the case of Microsoft, there will be a user certificate template. You can select and create user certificate

  This is an old document, but a computer certificate for the user configuration steps, you can see the steps to download the certificate user if his server from Microsoft:

  http://www.Cisco.com/c/en/us/support/docs/security/secure-access-control...

  In case you use the third serevr certificate, then you must check with them on how to download the certificate of the user

  See you soon
