Hello all ... I am successful in getting my ASA to create SSL VPN's with AnyConnect (v2.4.1012) using DoD Common Access Cards (Smartcards). I cannot however successfully query the OCSP servers. I keep getting the same error:
OCSP status check failed. Reason: Failed to verify OCSP response.
OCSP status check failed. Reason: Signature could not be validated.
I have followed the guidelines offered by DoD and Cisco:
I have checked 'Consider certificate valid if revocation information cannot be retried', applied a filter to only allow DoD Issued Certs access & tied login to AAA (LDAP - Active Directory) ... I still perform two-phase authentication by validating DoD issued certs and bounce the login credentials against our Ou ... But I have no way of checking certificate revocation.
