• Cisco ISE 1.2 and the ad group

  Hello

  I have Cisco ISE installed on my EXSi server for my test pilot. I added several ad groups at ISE as well.

  I created a condition of authorization policy, that is WIRELESS_DOT1X_USERS (see screenshot)
  Basically, I just replicate the default Wireless_802.1X and added Network Access: EapAuthentication, Equals, EAP - TLS.

  My problem is, I have been unable to join the wireless network, if I added my ad group to the authorization strategy (see screenshot). The user I is a member of WLAN USERS. If I removed the authorization policy group, the use is able to join the wireless network.

  I have attached the screenshot of ISE newspapers as well. I checked the ISE, AD/NPS, WLC, laptop computer time and date, and they are all in sync.

  I also have the WLC added as NPS client on my network.

  I checked the newspaper AD and I found it, it was the local management user WLCs trying to authenticate. It is supposed to be my wireless user Credential is not the WLC.

  It's the paper I received from the AD/NPS

  Access denied to user network policy server.

  Contact the server administrator to strategy network for more information.

  Hello

  The problem is with what ISE name, it's choosing to search of the AD. If you look in the ISE newspapers down, you'll see the username that use ISE (firstname, lastname) to search for the AD.

  In your certificate template see what attribute containst name AD (possibly the dns name or email or the name of principle of RFC 822 NT), go to your profile to authenticate cerificate and use this attribute for the user name.

• Cisco ISE with GANYMEDE + and RADIUS both?

  Hello

  I'm wired opening of authentication on a network using Cisco ISE. I studied the conditions for this. I know that I need to enable the RADIUS on the Cisco switches on the network. The switches in the network are already programmed to GANYMEDE +. Anyone know if they can both operate on the same network at the same time?

  Bob

  I suppose that Ganymede is configured (with ACS 4.x or 5.x) for the peripheral administration via telnet/ssh, and now you need the RADIUS (radius) to authenticate 802. 1 x. Yes they can both work on the same network at the same time.

• Cisco ISE 2.0 and WLC 5508 with 7.6.130.0

  I have looked on the release notes and compatibility n for ISE 2.0 and have not seen the answer to that. For the WLC 5508, the minimum AirOS is 7.0.116.0 but he limited the AAA authentication and support for comments. The recommended version of AirOS is 8.0.121.0.

  http://www.Cisco.com/c/en/us/TD/docs/security/ISE/2-0/compatibility/ISE _...

  What airos 7.6.130.0? I know that AirOS release works with 1.3 and 1.4, even if they show the same support for version 2.0. I'm just afraid that something may have changed with 2.0. I am concerned only about the AAA authentication and guest access. No BYOD, posture or MDM is necessary.

  No change. Works well.

• CIsco ISE with HP and Fortigate

  Hello

  I configured the switches HP 5820 X and 5130 for authentication radius AAA with Cisco ISE 2.0.0.306.

  The switch receives the response from authorization successful; but unable to connect. What are the Advanced profile Radius authorization attributes in

  ISE?

  In addition, ISE supports Fotigate firewall?

  Oh and Yes ISE supports any device using the RADIUS in accordance with rfc, it is usually only a question about this that av-pairs to send to that specific device, there is not really standard for this.

• 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.

• 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.

• 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.

• 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.

  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:

• 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?

  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.

• 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

  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?

• 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
