Fortigate Local CA

When you import, it will not show Local CA, it will just read CA Certificate. If your cert is really a CA certificate, then it will show under remote CA certificate. So this bears the question of, where are you getting your CA certificate? If this is the CA cert from your private root Microsoft CA or a root CA cert from DigiCert, etc... then that should work. If this is a signed cert from a CA, then no. Can you clarify and offer little more detail?
