• Test command of the AAA for EAP - TLS authentication for wireless users

  Hi all

  Can anyone suggest me the test command to verify the eap - tls authentication for the Cisco WAP's wireless.

  If it's an authetication jump we can use the command to test the connection below

  Radius of group aaa Testwap-01 #test [email protected] / * / o4 & yJ) NoL$ new-code %0
  Trying to authenticate with the server radius group
  User successfully authenticated

  But eap - tls is not delivered with the password. He insists that for the user name.

  We strive for remote location then test remotely before production.

  If someone help pls in that if we have a command to test or debug command to test this authentication.

  EAP - TLS requires a client certificate. How can you have a simple command that analysis without loading any certificate on the router/switch? It does not exist. This is why eap - tls is not considered an easy to deploy eap method: because it can go wrong on several levels.

  The aaa command test performs a PAP authentication, therefore, it tests the connectivity of the base RADIUS and name of user and password.

  If it works, the only thing that can break for eap - tls are certificates, as well as the radius server will be able to tell if something worng.

• Requirement of CA for EAP - TLS

  Hi all

  I know there is a requirement of Cisco for "User certificates" and "AAA certificates" used in EAP - TLS. Anyone know what are the requirements for the cetificates CA in EAP - TLS please?

  Thank you.

  Hello

  You must have 2 certificates on the client and your radius server.

  First certificate is the "root" Cert which is the same on both devices.

  The second certificate is the 'user' Cert that is unique for each client-server and aaa.

  Below are more details for EAP - TLS:

• Install certificates for EAP - TLS does ACS does not work

  Hi all

  I have two problems.

  I produced a CSR ACS and sent my people to windows this and they published my ACS with a certificate. Cool.

  I'm going to download the GBA and I put a 'private key file?

  What is this file? and where can I get a? What is this long string of characters that generate the CSR, I sent the boys of windows?

  Also, I managed to just put any old rubbish in there? and I was surprised he accepted.

  Restarted the service IS and I tried to turn it on eap - tls on the "Overall Authentication Configuration" page to get only the message

  Could not initialize authentication PEAP or EAP - TLS because that Protocol

  certificate is not installed. Install CA using "ACS."

  «Configuration of CA page»»

  Now, I'm a little confused, because if have the installer GBA incorrectly, because of my lack of understanding of what this private key file and how it relates to all which?

  Thx a lot indeed.

  Ken

  I'm having the same problem. It seems the guys from windows to generate a cert that it must be exportable, which offers also private key file. I tried the following without success document. It can work for you, however, http://www.cisco.com/en/US/products/sw/secursw/ps5338/products_configuration_example09186a008020a45c.shtml

  I also tried to have the ACS to generate a certificate self-signed, that works. But on the client, you must uncheck the box validate the server certificate because GBA is not a trusted certificate servers. Right now I'm trying to understand how ad to publish the ACS as a trusted cert server so windows knows to do trust the cert of the ACS. Through all this, I found that you can configure in several ways, the most difficult part is to find a way that works for you.

• C4402 and ACS5.2 for EAP - TLS

  Hello

  I'm putting in place ACS5.2 to authentic my portable computer clients with automatic certificates to an ad group.

  Cisco 4402 is successfully allowing them to network on WEP. Now, I need to use EAP - TLS and CERT to authentic.

  I'm fighting with the ACS5.2 config. I ' ve worked through added a cert CA, added to the AD domain, I have now configured Athen profiles and Access Services. "

  With each step any help would be greatly appreciated.

  Hello

  If you only need configuraiton side ACS, right?

  I think you need to move your thread on security identity and AAA forum here: https://supportforums.cisco.com/community/netpro/security/aaa.

  However, here are some links that you might find useful:

  https://supportforums.Cisco.com/docs/doc-21679

  https://supportforums.Cisco.com/docs/doc-24868

  None of them show exactly EAP - TLS configuratoin, but you can follow the configuraiton PEAP with AD, then you change your settings to allow the EAP - TLS and configure the necessary certificates on the client and the server.

  If you still have concerns, please ask. But if you move the thread on security forums you can find more people help ot.

  Good luck.

• LEAP EAP - TLS on WLC

  Hello

  I need to deploy authentication of certificate based for some devices of client for Intermec for a customer. I intend to use a separate SSID for this. There are other existing SSID who based radius authentication.

  question: if I don't select any server radius for this eap tls ssid and select only "BOND", going to work? Or will the WLC always find already defined radius servers and authentication failure?

  Question2: If above is not possible, I have to go for eap tls with ACS. someone had some easy steps to get eap tls operational? (1252, wlc 4400, acs 4.1 windows CA LAP)

  concerning

  Joe

  You will be able to use local for jump car as long as you do not specify a server radius on this ssid. Then you can have a different ssid to break the eap - tls pointing to a RADIUS.

• ACS 4.0 EAP - TLS Cert does not

  Hey,.

  so, I have generated my certificate signature request, took it to my CA, a cert. "ACS Certification Authority Setup" I have installed on my device ACS, then 'Install ACS certificate' installed (he parked in the privkey and password so I guess he got that comes from the cert file). I then add the CA to "change CTL. All of this goes off without a hitch.

  However when I try to add the "certificate revocation list" I am unable to add the two LDAP:------and http://. I confirmed that the http:// is working on the certification authority, and all the possible indications are that the ldap protocol works too but I can't test with tools.

  When I go to "System Configuration"-> "Global Authentication Setup"-> "allow EAP - TLS' I get the following error.

  Could not initialize the PEAP or EAP - TLS authentication protocol because the certificate authority is not installed. Install the certification authority by using the "ACS Certification Authority Setup" page.

  Exactly, which is not installed on the certificate? It is on the ACS server, it is configured and the date range is correct.

  I've been banging my head against this all day and could use some suggestions. :)

  Hello

  For EAP - TLS to work you must use external CA installation such as Microsoft or Rapid SSL etc and auto generated in ACS certificates supports PEAP support but not EAP - TLS.

• Authorization of EAP - TLS machine uses ACS 5.2

  Hi all

  I've been struggling with this during a few days now and I think there must be something I'm not quite understand.

  We strive to deploy new wireless infrastructure using windows, APs from Motorola (with switches RFS) wireless clients and using a Cisco ACS as Radius Server 5.2.

  Trying to get EAP - TLS to work, I can get customers to connect if no actual authorization is used, but when I try to validate if the name of the computer in the client certificate belongs to a particular group, the authorization fails.  I don't see how to get the ACS to use the RADIUS "Username" it receives via the certificate allowing the machine.  The value of the Radius user name attribute is the name of the machine.  I would like the ACS to check to determine if this computer name belongs to a group, especially in the Windows AD.

  We started with PEAP-MSCHAPv2, but security wanted machine authorization so we thought that EAP - TLS was the only way to get it.  Now I'm not sure.

  I would like if someone can guide me in obtaining the ACS to validate if the computer belongs to a group in Active Directory using

  (1) EAP - TLS

  (2) PEAP-MSCHAPv2

  Thank you!

  Hello.

  Just check something here:

  You have in your policy, in terms of identity, AD1 (or certain Sequences of identity store with inside AD1) listed as Source of identity?

• 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

• 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

• 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.

• EAP - TLS with ISE

  I read the Cisco ISE for BYOD and try to create an authentication policy for the EAP - TLS protocol. When I create the new policy and add a new condition, and then go to network access, EAPAuthentication is not an option. And I went to the element of strategy and created a new authentication, compond to condition added to the library. When I try to add to my authentication policy it does not choose it and said only the relevant conditions are selectable. Am I missing a step somewhere?

  Any help is greatly appreciated and thanks in advance!

  Hello

  If you want to use a different identity for BYOD devices store, all you have to do is change the dot1x default rule and add a condition above you by default of State/identity store.

  Add an attribute value of certificate - SAN/transmitter, etc., depending on what's your differentiator between the BYOD devices and active.

  Please see attached printscreen.

• ACS supports several Active Directory domains to 802. 1 x EAP - TLS?

  Hello

  I'm looking to implement 5.2 ACS using 802. 1 X, we have two distinct areas of AD.

  Now... That's the tricky part...

  One switch must support two ads, if an AD1 computer, it will be authenticated to the ACS using AD1 and applied to the VLAN1, whereas a machine located in AD2 is authenticated to AD2 and applied to VLAN 2.

  I'm looking for machine authentication, user authentication, so I guess I'll need two certificates of import of each ad.

  Can any expert please let me know if they think that this will be possible please?

  Thank you very much

  Yes ACS can support several areas of the AD, but you need to configure one of your AD domain name and the other as a LDAP database and it will not work because you plan to use eap - tls.

  The question I have is how ACS version do you use? If you use ACS 5.x, you can set up and storage of identity of sequence, so if the user is not you can move to the next store and this will prevent you from installing two certificates on each machine.

  You can then configure an allow rule for separate containers on which there are workstations (that's assuming that the machine authentication is used) for the AD database or the Protocol LDAP database, and then assign the vlan based on that.

  Thank you and I hope this helps!

• 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:
  http://SearchNetworking.TechTarget.com/originalContent/0, 289142, sid7_gci945257, 00.html

  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.
