SiteScope - OBM Certificate Exchange

Hello,

I'm working on a fresh integration between SiteScope and OBM, both working under SSL. I'm having trouble understanding how to exchange the certificates between the servers and have the following questions:

1. Which is the certificate that I have to exchange between them? In the documentation it only mentions "CAcertificateFile" but not the extension nor the command to extract the certificates from SiteScope/OBM.

2. If they share the same CA authority (ROOT Certificate) do they still have to exchange certificates?

3. The CA certificate mentioned in the documentation is the same as the CA certificate authority or are they different?

Thank you so much beforehand.
