Description
This article describes how to import a CA certificate for SSH/SSL inspection on FortiGates managed by a FortiManager.


Solution
Here is a step by step guide on how to add and install a CA certificate on FortiManager.


1. Add the CA certificate and CA private Key under Device manager > CLI only objects > VPN > Certificate > Local.

Once this is done, it will be available for the certificate to be used in SSL/SSH inspections. 

After this step, config status under device manager is changed to modified. Can be ignored as this will be back into synchronized status after following all the steps. If the administrator wishes to just install the certificate for later use, proceed with install device settings . Else proceed to Step 2.


2. Next step would be to create a Dynamic Object mapping under Policy & Objects > Object Configurations > Dynamic Object > Local Certificate > Create new, in the 
per device mapping select the device (to which the CA certificate was imported under device manager) and Certificate and click on OK.

Added certificate under device manager will appear here in the drop down list only if the ADOM version is matching the OS version running on the device. 
For example: FortiGate running v5.4 should be added on ADOM version v5.4 or if there is a mismatch the certificate will not show up in this list.


3. Once this is done, create a New (or edit an existing) SSL/SSH inspection profile selecting the CA certificate which was just created in Step2.

4. Use the SSH/SSL inspection profile in the policy and install it on the FortiGate. This will have the certificate and its references like the SSH/SSL inspection profile and policy in which used the SSL/SSH inspection profile installed on the FortiGate.
