Cisco NAC > Client Certificate
The client (or CA) certificate authenticates end-user clients with the Cisco ACS server. The OfficeScan server deploys the CA certificate to clients along with the Cisco Trust Agent (CTA), so you must import the certificate to the OfficeScan server before deploying CTA.
Type the exact file path of the certificate (for example: C:\CiscoNAC\certificate.cer).
Click Import.
To clear the field, click Reset.
See the OfficeScan Administrator's Guide for detailed information on exporting the certificate and saving it to the OfficeScan server.
