Cisco VPN :: ASA 5540 AnyConnect Client Certificate Authentication
Jan 22, 2012
I want to connect with AnyConnect Secure Mobility Client 3.0.2052 to ASA 5540 Version 8.4 and SSL Premium License.The clients using Maschine Certificate to authenticate to ASA. This works fine.Now I want to setup a DAP to verifiy the client against the Microsoft AD using LDAP. I configured LDAP server in ASA see:aaa-server LDAP protocol ldap aaa-server LDAP (inside) host ldap.com ldap-base-dn DC=x,DC=x,DC=x,DC=com ldap-scope subtree ldap-login-password ***** ldap-login-dn ***** server-type microsoft ,I can see that it works if I test the server via the testbotton in ASDM and I see it in CLI "debug ldap 255" also. But if I configure in DAP: AAA Attribute ID:memberOf = DomainMember I can not see any request to the LDAP server during I try to connect with the Client und the DAP doesn't match.

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.

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)

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.

Any instructions to configure an ASA to allow authentication by certificate only on an AnyConnect vpn?I'm running an ASA 5505 with 8.4(1) and AnyConnect 2.4.7030 on an Android phone.I currently have the AnyConnect client connecting ok using username / password for authentication.
I have loaded the company root certificate (internally generated) into the ASA "CA Certificates" and generated an Identity Certificate for the ASA.

ASA 5510 configuration for Csco anyconnect vpn client. Currently ASA is configured for self-signed certificate acces thru anyconnect ssl vpn. So the cert is being generated with every connection (of my understanding, I haven't found any identity certificate on the current configuration, at least on ASDM). Now I need to use a certificate from our local windows CA that we have at the office. I.e. self-signed certs should be changed with another one issued by our local office authority.
1. Generated new rsa key pair on the ASA
2. Generated CSR from identity certificates
3. Applied CSR to the windows CA and generated the certificate
Now I need to understand what is going to happen after I install this certificate on the ASA's identity certificates and apply it to outside interface. Is there anything to be done on the users side to use new certificate? Do they need to download and install the root certificate from the same CA? Do i need to have the root certificate installed on the ASA or identity is enough?

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.

I am a little new to Cisco ASA's but we bought two new 5540's to use as a new VPN solution for our company. We want to implement Cisco Anyconnect full client and Clientless based solutions for our end users. I am having problems working with setting up access lists based on groups. I simply want to create access-lists to certain IP's based on groups. I ultimately want to get to the point where we have Dynamic Access Policies that are based on Active Directory Groups allowing access to back end servers based solely on their group membership in AD. But first I need to figure out how to just apply an ACL on a group.

We've deployed WebVPN on Cisco ASA 5540 and its working fine with no trouble in relation to connectivity. My Anyconnect VPN users are able to download the client and connect to our corporate network.However, sometimes when I try to connect after entering the credentials it keeps saying Login failed.

I have a ASA 5540+SSM-40 on which I have configured webvpn and it's listening for connections on the outside interface. It can be accessed from outside the network (the internet) and works just fine. The problem is, I want to access it from inside the network as well but it doesn't work. I can't ping or connect in any way to the IP address of the outside interface from inside (so I suppose it's not strictly related to the configuration of the webvpn).
I don't think it's a ACL issue because the only ACL filtering I do is on the OUTSIDE-IN (facing the internet), the rest are set to permit any.
What I have to do to be able to access the IP address of the outside interface from networks behind the inside interface?

I have a strange issue with certificate based authentication anyconnect. We have an ASA with two internet links, both have a CA authenticated Cert for anyconnect VPN’s. We have an anyconnect client profile also, when we simulate a link failure on the ASA the anyconnect should automatically attempt a re-connect to the backup server list in its configuration (which is the other interface on the ASA 5580) which it does but we get a certificate trust error.

When i'm trying to connect using stand-alone Anyconnect (not through the web), I got the SSL error message "The certificate you are viewing does not match the name of the site you are trying to view" (attached).
The certificate I installed for the SSL connection on outside interface got Subject CN=testvpn.mydomain and Subject Alternative Name (SAN) --> DNS Name = testvpn.mydomain
It seems to me that instead of connecting to testvpn.mydomain, anyconnect try to connect to the its IP address. I did try to remove the IP address in Server List in the profile, but it still doesn't work.
If I'm using Clientless (through browser), I don't received this error which means the certificates installed correctly.
Is that a bug on anyconnect 2.5.2019 or is there other ways to force anyconnect to check name instead of the IP against the certficate?

We currently are using the anyconnect client using certificates for authentication (ASA 5520 v8.4). It works pretty good but I can only get it to work on a profile basis on the clients laptops. We are running windows 7 and if multiple users need VPN i have to install the certificate for each user. I have changed the xml profile to read the certificate store to "all" and true for certificate store override. I am installing the certificate in the trusted root certificate store. Is there a way for the anyconnect to authenticate for all profiles (users) for the laptop?

I am having some problems with my AnyConnect configuration.I have configured AnyConnect (ssl vpn / webvpn) on my Cisco 1841 Router, and I can access it from a web browser and start the tunnel, then anyconnect starts up and then the problem come, because when AnyConnect is trying to connect it comes with an error saying "The certificate on the secure gateway is invalid".
I have read almost all of the threads in here about the problem also tried to make a new certificate, but nothing is working?
BTW: I am using self-signed certificate?

I just upgraded our AnyConnect package on our ASA5510 from 3.06xxx to 3.1. When I tried to log in to the website to automatically install the client, it showed me a big error saying the Certificate is untrusted and I have to explicitly accept it. After accepting it, I had to restart the installation.Is there a way to disable this strict certificate trust setting? We don't have a valid SSLVPN certificate yet, but this big error will confuse endusers.

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.

I have an anyconnect account set up using version 3.0.5080 and connecting to an ASA 5510 base 8.2(2)17. We are using certificates for authentication. If I try and use the account on a windows machine it all works fine.
However on a mac running Lion if I try and connect via a web browser or already have the anyconnect client loaded and try to connect I always get “certificate Validation Failure”. I double checked the certificate was correct and am sure that is correct as it is the same certificate on the Windows and the mac. After searching online I have also tried editing the anyconnect profile to so it is set “certificate store override”, and put the certificates and key in the “user/.cisco/certificates” and “/opt/.cisco/certificates” folders.
After further testing, if I change the anyconnect connection profile to “authentication aaa” I can connect fine. Then if I disconnect, change it back to “authentication certificate” I can connect fine the first time, but all the following subsequent efforts I make fail. If I repeat this process this happens each time, I can connect the first time but after that it fails with the same “certificate Validation Failure” error message. When it connects this first time I checked and confirmed that it is definitely using the certificate. I have also tried using both authentication methods (“authentication aaa certificate”) and had the same problem.
This leads me to believe that my configuration is correct and it is some bug in the anyconnect client or the ASA image. I have had a look through bugs and read somewhere that there was a bug on earlier versions of 8.4, but nothing about 8.2.

I have an ASA (8.4.5) configured with a connection profile that does AAA and Certificate authentication. Once I have the anyconnect 3.1 on a win Xp system, it works perfectly. When I do a web install, it goes through the normal download, log-in, re-download then says "Certificate Authentication Failure" If I change the profile to AAA only, it installs fine. I even get the error if I launch from the web after I have the client on the PC. Why this is not working?

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]

I have a remote access VPN profile configured on an ASA 5540. This profile is almost identical to the same profiles configured on other ASA 5540. The profile is linked to Active Directory for authentication. For some reason, users are not being prompted for the domain name field when connecting to the firewall, on the other firewalls they get prompted for all three (user/pass/domain).
All the firewalls are running 8.0(4) 32. And the following is the configuration of the firewall that I am experiencing issues with:
ip local pool TESTVPN 10.244.124.1-10.244.127.254 mask 255.255.252.0
group-policy TESTCERT internal
group-policy TESTCERT attributes

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.

Looking for the steps to configure wired clients using certificate authentication only
- i.e., once a certificate is presented to the ACS that is issued by a trusted CA, the connection is permitted.
No need to tell me about switch configuration.
