Cisco AAA/Identity/Nac :: ACS 4.2 Certificate Based Authentication And Windows 7
Jan 9, 2012We use a combination of Cisco ACS and Cisco catalyst 3560 switches for network authentication and authorization. Clients (Windows XP) have a certificate installed which will grand access to the network and put them in the correct VLAN. So far, so good. Some users are testing with Windows 7 in the same set-up as above and run into strange behaviour. The problem is that after a random timer the machine gets de-authenticated and nothing besides a reboot works to get the computer authenticated again (from a Windows point of view). It looks like this only happens to users who are using a certificate to authenticate, Windows 7 MAC bypass users have no such problems. If it occurs, the following logging appears in ACS: [code] We are using ACS 4.2(0) Build 124 and 3560-48PS switches with IOS 12.2(55).

Jan 30, 2012There is ASA with remote access VPN and users are authenticated using third party signed certificates (CA is not local in ASA).When user certificate expires i can see it in syslog messages. For example:
%ASA-3-717009: Certificate validation failed. Certificate date is out-of-range, serial number: (...)
I would like to know if there is an opportunity to view user's certificate expiry date beforehand, say, 3 days before?

Dec 20, 2011Digital certificate on the ACS Wireless network:
Checking the configuration of the Wireless Notebook no longer requires the digital certificate of the ACS and NVR122 NVR123as worked in the past. The certificate is generated for the ACS root CA trusted by the COMPANY, so that the public CA certificate supersedes theprevious ACS. Therefore, any host that is in the field of company would have access to the wireless network. With this, the 8021x is working with a certificate that is common to all hosts in the field of business. How do I change it?

Jun 14, 2011Currently I'm using a self signed cert issued by ACS. We are having an issue where occasionally we see in our Windows 7 logs that Windows did not like the self signed cert from ACS when doing dot1x authentication for our Windows 7 clients. We are using the built in dot1x client that comes with Windows and have the "Validate Server Certificate" unchecked but still see this error occasionally. I've tried issuing a CSR from the ACS server and going to Thwate and getting a test cert but everytime I paste the CSR into the field at Thwate I get an error about invalid cert type. You have to choose from a list of server types. I've tried several different ones. I've also tried issuing the request from a WIndows server and when I try and import the files I get a invalid key error. How to get certificate working from Thwate or Verisign?

Nov 7, 2011Been tinkering around in our ACS 5.2 appliances today to setup PEAP. I generated a self signed certificate under local certificates which I want to remove now. But when I try to delete it I get the following message:
This System Failure occurred: Certificate is associated with a protocol. Hence it cannot be deleted.. Your changes have not been save. Click OK to return to the list page.
I assume this is because it is associated with the EAP protocol, but I cannot uncheck the box when I edit the local certificate. How can I get rid of this test certificate?

Feb 9, 2012i have a wireless deplyoment with WLC 5508, ACS 5.2 and several AD connected by LDAP. It is required that users are authenticated by certificates additional the user should only get access to the wireless environment when the user is found in a certain security group in the Microsoft AD forrest. The certificate based authentication is working without any problems, except the lookup into the AD isn't working. Here are the Details of the "Evaluting Identity Policy"
Evaluating Identity Policy
15004 Matched rule
22037 Authentication Passed
22023 Proceed to attribute retrieval

24209 Looking up Host in Internal Hosts IDStore - Alex Dersch
24217 The host is not found in the internal hosts identity store.
22016 Identity sequence completed iterating the IDStores
but the user can access the WLAN just without verifying the user in the AD.
i tried the to enable Binary Comparisation but then the Authentication is not working any more. I get the same Identity Policy result as above.
i configured the Binary Comparisation as below:
I though with the binary comparisation i'll be able to verify the existance and the status of an user in the Active Directory.

Cisco AAA/Identity/Nac :: ACS 5.3 Group Mapping Based On (G-CRP-SEC-ENG)
Apr 30, 2012I am configuring a new ACS 5.3 system. Part of the rules is that I want to match the users specific AD group membership, and match appropriatly to an identity group.What i'm trying to do is say that if the user is a member of the AD Group (G-CRP-SEC-ENG) then associate them with the Identity Group SEC-ENG. The under the access service, authorization portion, i assign shell profiles and command sets based on Identity Group.It seems that the ACS server will not match the AD Group for the user, and it will match the Default of teh Group Mapping portion of the policy every time.
I tried several configuration choices from : AD1:ExternalGroups contains any <string showing in AD>, AD1:memberOf <group>.Is there something special i need to do in the Group Mapping Policy to get it to match and active directory group and result in assigning the host to an Identity Group?

Cisco AAA/Identity/Nac :: ACS 5.3 Authorization Of User Based On MAC Address
Aug 23, 2012A short background. Our corporate SSID is being migrated from using PEAPv0 to EAP-TLS. This restricts access only to company notebooks. Additionally we have barcode scanners which are used to inventory assets. Those devices are not able to use EAP-TLS as they cannot be integrated in the domain and being unable to do certificate based authentication.
As a workaround we planned to use another SSID with access to the same network but using PEAPv0 as authentication method, basically the same SSID but with a different name. As this naturally allows anyone to access the corporate network with a valid username/password I now wanted to add another step into the authentication process - the MAC of the device. I know I can do the filtering at the WLAN controller, but as it has a limited database as well as the fact that it is cumbersome to maintain the MAC list on all the controllers I thought I can do it over our ACS system.
I am now trying to accomplish the following: The user gets authenticated via the internal user store, which is succesful. Now I want to authorize the user via the MAC address, which is stored in the internal host store of the ACS, if access is granted or not.
For this I created the following policy:
Service Selection Policy -- (Rule based result selection)
-- (NDG:Device Type in All Device Types:Wireless And RADIUS-IETF:Called-Station-ID contains <SSID>) | Result: PEAP access
-- Default | Result: DenyAccess
Service PEAP access Identity: Internal Users -- (Single result selection) Authorization -- (Rule based result selection) -- Internal Hosts:HostIdentityGroup in All Groups:Valid_MACs
When I then try to access the wireless network I won't get authenticated. The error I get, when I look into the logs is: 15039 Selected Authorization Profile is DenyAccess
Is it not possible to use one identity store as "attribute database" for the other identity store?
Cisco AAA/Identity/Nac :: ACS 5.2 Assign VLAN Based On AD Group?
Apr 18, 2011I'm trying to configure ACS 5.2 to assign the VLAN to a user dynamically based on the AD group that the user belongs to. I've gone into:

and selected the group name from the AD. If I understand correctly, I should now see this group under:
Policy Elements -> Authorization and Permissions -> Network Access -> Authorization Profiles -> Common Tasks -> VLAN ID/Name
However, it does not. Am I missing something?
Cisco AAA/Identity/Nac :: 5508 / ISE / BYOD / Windows Clients Reject ISE Local-certificate
Mar 26, 2013We are deploying BYOD with Cisco ISE 1.1.2 and WLC (5508) using 802.1x authentication.Windows clients cannot connect to 802.1x SSID with the following error on ISE:Authentication failed : 12321 PEAP failed SSL/TLS handshake because the client rejected the ISE local-certificate
The client doesn't have preconfigured wifi profile or root certificate installed.The concept of BYOD suppose that you can connect your device without any installed certificates and preconfigured wifi-profiles.
The problem is that Windows 7 supplicant does not send TLS alert in pop up window, when connecting to 802.1x SSID.If this alert is seen, than you can accept it and proceed the connection. After that you will be asked to install ROOT-cert, get your own cert and etc.So, the question is: how to make the windows supplicant to show the pop-up window with TLS alert?
p.s. the attached file shows the example of pop up TLS-alert window
