Cisco anyconnect 3.1 - Certificate Validation Failure.

When i try to start a SSL VPN connection to the ASA(8.4) with anyconnect 3.1, Cisco anyconnect receives a message saying "No Valid Certificates Available for Authentication".

Prior to the test;

     On the ASA, i have obtain CA certificate and its identity certificate. (Both certificates obtain from windows 2008 CA).

          * ASA identity certificate's have EKU attribute = Server Authentication,   Key Usage = Digital Signature, Key Encipherment.

     On the PC in which anyconnect installed, i have obtain User Certificate (this User certificate also obtain from the same windows 2008 CA)

          * Prior to obtaining User certificate from the windows2008 CA, ASA acts as a SCEP proxy onbehalf of the client PC.

          * User Certificate's has EKU attribute = Client Authentication.

As in the ASDM Logs, it almost work.

In days of troubleshooting, i still could not find the cause of this problem. Error message as appeared on anyconnect;

Just run into this as well.

Just run into this as well. We have CRL checking turned on. Turned out to be the CRL server was down. But that was the same message I got when the client wouldn't connect.

Re: Cisco anyconnect 3.1 - Certificate Validation Failure.


I'm using Anyconnect with a Machine certificate to autheticate : it works with Windows PC (having xml profile in C:\ProgramData\Cisco\Anyconnect\Profile ) but not with Mac OS (with same xml file in /opt/cisco/anyconnect/profile).

With Mac OS : "Certificate validation failure" message pops up when trying to connect !

In Anyconnect messages : "No valid certificates available for authentication"

It seems like the certificate is not found on the Mac.

Do you know if there is differences in the XML file between a Mac from a Windows PC ?

Thanks for your help,
