• Authentication EAP - TLS with ACS 5.2

  Hi all

  I have question on EAP - TLS with ACS 5.2.

  If I want to implement the EAP - TLS with Microsoft CA, how authentication computer and user will be held?

  Understand that the cert is required on the client and the server end, but is this certificate to the computer links or links to individual users?

  If the links to the user, and I have a shared PC connection by few users, is that each user account will have their own certificates?

  And each individual user will have to manually get the CA cert? is there another method that my environment has more than 3000 PCs.

  And also if it binds to the user, any user can get their CA cert with their AD username and password, if they bring in their own device and try to get the CA certificate, they will be able to properly install the cert in their device on the right?

  I hope you guys can help with that. Thank you.

  Hope this will answer most of your questions:

  Client certificate or user

  Computer certificate

  http://www.Cisco.com/en/us/Partner/Tech/tk59/technologies_tech_note09186a00804b976b.shtml#T15

  In the case of EAP - TLS we have the certificate of computer and user installed on the machines.

• EAP - TLS with WLC 4404 (choose which layer option 2)

  Hi all

  I want to install a WLAN that uses EAP - TLS.

  WiFi PC <----->LWAP <------>WLC <---->Radius Server

  Should the layer tab 2 for security on the WLC which option I use for the following: -.

  Security Layer 2 (I'm assuming that WPA + WPA2 than what laptops will use)

  Key auth Mgmt?

  I'm a little confused by the 802. 1 x in two of these fields, a security layer two and one for Auth key Mgmt?

  Thx a lot indeed guys,.

  Ken

  You would choose layer 2 security: WPA + WPA2

  Then in the settings WPA + WPA2 choose political WPA2 with WPA2 encryption. Under authentication key Mgmt select 802.1 x.

  Now if you need the use of WPA policy, then also choose TKIP for this.

  Choose your radius servers so for your AAA server tab.

  That's all.

• 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:

  CSWinAgent 2009-11-30 16:32:13 0140 3672 0x0 customer who connects from x.x.x.x:2443

  So I did a test of the ASA to see if the host is a problem (until changes have been made it was not a problem):

  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?

• 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,

  Ryan

  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.

• Cisco ACS with external DB - EAP - TLS

  Hi guys,.

  I understand how the EAP - TLS exchange works (I think), but if I have a client (with or without wire) that uses EAP - TLS with a CBS, I confirm the following.

  Let both users and computer certificates are used:

  1. customer and ACS are with each of the other automatic certificates to ensure they are known to each other. The eap - tls Exchange.

  2A. At any given time and I'm assuming until the successful eap - tls message is sent to the client, the ACS to check if the user name or computer name is in the AD database?

  2B. Wot is the parameter that is checked on the AD database?

  I read here that it can be: http://www.cisco.com/en/US/docs/net_mgmt/cisco_secure_access_control_server_for_windows/4.1/configuration/guide/peap_tls.html#wp999517

  Client certificates

  The client certificates are used to identify with certainty the user in EAP - TLS. They have no role in the construction of the TLS tunnel and are not used for encryption. A positive identification is made by one of three ways:

  CN (or name) comparison-compare CN in the certificate with the user name in the database. More information on this type of comparison is included in the description of the subject field of the certificate.

  Comparison of SAN-compare the San in the certificate with the user name in the database. It is only supported from the ACS 3.2. More information on this type of comparison is included in the description of the field another name of the subject of the certificate.

  Binary comparison - compare the certificate with a binary copy of the certificate stored in the database (only AD and LDAP for that). If you use the binary comparison of certificate, you must store the user certificate in a binary format. Also, for the generic LDAP and Active Directory, the attribute that stores the certificate must be the standard LDAP attribute named "usercertificate".

  3. with the foregoing, if options 1 or 2 are used (CN or SAN comparison), I guess it's just a check between a value out the CERT of the ACS and checked with AD, is that correct? With option 3, GBA exercise a complete comparison of the certificate between what the client and a "cert stored client" on the AD DB?

  Please can someone help me with these points.

  I'm so lost in this kind of things :)) I think.

  Thx a lot and best regards,

  Ken

• 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

• 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.

• ISE and EAP - TLS

  Hello

  We plan on implementing eap - tls for our iPads company and in the past, I've successfully tested it authentication with the ACS5.3, but now that we moved to ISE (1.1.1.24) I get an error.

  Result of the strategy of the 22045 identity is configured for password based authentication methods but received certificate authentication request

  I tried two different profiles, one with a certificates and credentials of the AD and the other with just the certificates but the error message are the same for both.

  EAP - TLS is enabled in the result of the 'Access to the network by default' authentication.

  Anyone can shed some light on where I'm wrong?

  Thank you

  Martin

  Yes that's right, the certificate that is presented to the ISE does not include the identity of the client, this is the reason why the attempt fails.

  Hello Patrick.

  Unfortunately, I don't think that's currently possible in the world of wireless Cisco with a unique SSID. For your example, you will need two separate SSID. Something similar has been asked before:

• 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.

• 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

• 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.
