Cisco VPN :: 3rd Party Certificate And AAA Authentication ASA 5520

Oct 24, 2011

I am using a cisco asa5520 and i have set up remote access vpn with an AnyConnect connection profile.In the connection profile i have set up that users should authenticate using both certificate and AAA.Due to a high security requirement, the user certificate is issued from a 3rd party. This is working fine and the user now need a valid certificate and a username/password to authenticate successfully.I added the CA certificate as a associated trustpoint on the ASA box to get the certificate verification working.Problem:If Jane and Joe both have a valid certificate AND a valid username/password, Jane could authenticate using a combo of Joes certificate, and Janes username/password. Both are valid (isolated), but i only want jane to be able to authenticate with her username/password and her personal certificate.

Cisco VPN :: ASA (version 8.0.4) / VPN Connection From IPhone / Could Not Validate Certificate

Feb 9, 2011

I have some iPhone in my company and they connect to VPN through an ASA (version 8.0.4). The vpn connection use a certificate to validate that the device can  connect. All my devices used the ASA IP address to connect, I decide to change that and use a name to connect ( DNS resolution made by the ISP), a generate a new certificate and made a new vpn connection profile. My PC, mac book pro can connect using the new connection, but my iPhone display the message : "Could not validate certificate". I've checked all the configuration and can't find where the difference between my two connection profile.

Cisco :: Certificate Authentication At WLC 4402

Jan 18, 2012

we  are using Cisco Aironet 1130 AG and a Cisco 4402 WLC in our network. The certificate service is installed on a Windows 2008 R2 server. We use a standalone Root CA with a Enterprise Sub CA hierarchy. Issueing certificates to clients works fine. The vendor and ca certificates are installed on the WLC and the user have his user certificate. During implementation we used following document: url... Instead of Anonymous Bind, we use a service user to read in AD (works fine, too).
 
We use the Intel/PRO wireless utility on our Testclient and configured it for EAP-FAST and TLS. We can select the installed certificate in the utility, but when we try to connect, the utility throw the message: "Authentication failed due to an invalid certificate".We´ve logged the WLC and thats a part of the logfile (i´ve greyed out all enterprise data): [code]

Cisco VPN :: Anyconnect 3.1 Certificate Authentication

Dec 20, 2012

I am doing a proof of concept with anyconnect and certificate authentication. with 3.0 i was able to do this with a certificate from my CA and a client cert in a smartcard. I have upgraded to 3.1 and now it doesnt work anymore ( i need 3.1 and Asa 9.0 because of IPv6 Split-tunneling).Reading the forum i got some info that the ASA cert must have a EKU value of 'Server Authentication' and the client cert must have a similar EKU (client Auth)

Cisco VPN :: ASA 8.0.4 - IPad Client Certificate Authentication?

Jul 8, 2010

The IPAD VPN works great over token, radius and local authentication. But now we need to authenticate vpn client via digital certificate (only vpn authentication between client and gateway)? I'm not sure which certificate we should buy to authenticate vpn client.The plan is to install digital certifiacte on VPN Gateway (CISCO ASA 8.0.4) and IPAD Cisco IPSec client to eliminate user/pass authentication.

Cisco AAA/Identity/Nac :: ACS 4.2 Certificate Based Authentication And Windows 7

Jan 9, 2012

We 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).

Cisco Switches :: ESW-540-24p - Switch Refuses EAP Certificate Authentication

Jan 26, 2012

The problem is that with any EAP method of authentication that utilizes authentication with a certificate or smart card the switch will somehow impede authentication with the radius server. The EAP Methods I have tried on a SG-300-28P and ESW-540-24p switch are:EAP-TLS, EAP-FAST, PEAP Smart Card, I know that the radius server works because when I switch to a different switch the client works just fine, or if I keep the client on this switch and use any password method (PEAP (MSCHAPv2), MSCHAPv2, EAP-MD5) it also works. In both cases the radius server logged a EAP Timeout. Again this only happens when any EAP method or version of authentication used deals with certificate authentication.Only with the 3 Cisco small business switches we have, have I ran into this problem. The Cisco Aironet and Other Switches (by other manufacturers) work just fine.

Cisco VPN :: ASA 8.2(5) / AnyConnect Fails At First Attempt (certificate Authentication)

Jan 25, 2012

I'm trying to set up vpn with ASA 8.2(5) and Anyconnect 3.0.4235. The goal is  to force user to connect from registered machines only (winXP & win7 x32 and  x64). To do this, I used machine certificates issued by own CA. Certificate  is installed in machine store. I use double authentication (aaa & certificates). Everything works fine, AnyConnect browses cert store, ASA  validating machine certificate, then user is prompted for username/password  and finally if all is correct - connection is established.My problem is, that for new installation (new host), AnyConnect fails at first connection attempt. If I use aaa authentication only, connection is established, but if I use aaa & certificates - connection fails. The  appropriate .xml profile is predeployed at client host asa well as machine and root certificates.Important: When first try (aaa auth) succeded, others are always OK (with aaa. certificate or aaa & certificate authentication). Only the first one fails.The goal is to succesfuly establish connection with aaa & cert.
 
With DART i get:
******************************************
Type        : Error
Source      : acvpnagent 
Description : Function: CTransportWinHttp::WinHttpCallback
File: .CTransportWinHttp.cpp
Line: 2150

[code]....
 
Certificate is valid for sure, and as I mentioned before, if first use aaa only, the second try is OK. At ASA with debug crypto ca 255 can't see any certificate from client.

Cisco VPN :: ASA 5540 - Client IPsec Authentication Using Digital Certificate

Sep 11, 2011

I need some clarification with configuring my ASA 5540 with IOS 8.3x for remote client certificate authentication.
 
I have my root certificate from the Microsoft CA but not quite sure if the outlined steps in the Cisco websites below are exactly what I need since the firewall seems to be generating the certificate to be used. [URL]. 
 
My setup is such that the CA will issue certificates to the remote clients and to the ASA firewall, and the remote clients will authenticate and connect with their certificates which the firewall constantly updates using the CRL update from the CA. The dhcp pool is to be issued by the domain controller on the inside network and not on the firewall. Any examples or best practice steps to achieve this.
