What's a CA30?
Latest Certification Authority version from DoD Common Access Cards (CAC).
Used for PKI authentication.
We are having the same issue. Its a problem with the PKI module, your best bet would to be to put in a ticket with DISA. This really isn't related to McAfee.
When you export the certs from your CAC they're saved as .cer files
The server only likes .crt files
So, just change the extension and import them.
