OCSAgent : SSL error with OCS Server Linux

Hello,

I'm setting up my ocs  but I have issues with the agent on Windows. On the logs, I see

COM SERVER => Sending HTTP Post request to URL <https://myhost.ad.local/ocsinventory>
WARNING *** COM SERVER => Failed to send HTTP Post request <SSL connect error>
COM SERVER => Cleaning cURL library
ERROR *** AGENT => Failed to send Prolog <SSL connect error>

The file cacert.pem I use for the Agent has been downloaded from the Linux server /etc/pki/tls/certs/ocsng.pem and has been renamed to cacert.pem

So, I figured it out by myself!

The trick here is to set this value

SSLProtocol all

​This value will permit the OCSAgent to communicate with the server.

So now my question is :

How can I do to force agent using TLSv1.2 with my Linux Server OCS?
