We have enabled EAP-TLS authentication for our wireless LAN end user in our network setup , And we have defined certificate on our old acs server 3.3 from a third party CA . I want to use the same certifcate which is being used in 3.3 ,how i can copy that certficate from 3.3 and get it installed on new acs 4.2 .
View 7 RepliesThere 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?
i am working on ISE 1.1.1, surprisingly i couldn't found certificate authority certifiate at certificate operation anymore.
would it be the change on GUI? So now where i can import the CA certificate to ISE?
Currently 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?

View 7 Replies View RelatedBeen 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?

View 3 Replies View RelatedWe 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).

we currently have a remote access asa setup using Anyconnect with self signed certificate, and several users in the certificate database as we are using radius and certificate for authentication.
I want to purchase and obtain a trusted CA signed certificate (such as Verisign) and replace the current self signed cert.
My question is will I have to reset the current CA server of the ASA and replace the certificate user database? ie start from scratch.
Currently the ACS 5 is authenticate the iPhone/iPad by using the MAC address (which is entered manually) and AD user/password, i need to do that with certificate, so it will be scalable.

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?
I have just renewed the self signed certificate on a v5.2 ACS and expiry date of 2013 is showing in the ACS GUI. However, when I start an ACS Admin session and view the certificate information in the browser it is showing the old expiry date of 2010. I have tried this in IE and Firefox and the certificate information is the same.
Is there a way I can get the browser to pick the new certificate ?

We 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
