[Openvpn-users] Query for Supporting a CA hierarchy for TLS server

[Sean.OConnell@xxxxxxxxxxxxxx]

Hi, 

I want to configure a TLS server, client to use a hierarchical
structure of CAs i.e. 

RootCA  - IntermediateCA - TLSServer Certificate

RootCA - IntermediateCA - TLSClient Certificate


The examples only cover a PKI infrastructure of depth
1. 

However, I am a bit stuck in figuring out how to configure
the 'ca', 'cert' options on the server and client 
to handle the 3 required certificates, the Trust Root,
the Intermediate certificate and the Operations End Entity

Certificate.
I know that the certs must be in PEM format, and you can
concatentate them together, but alas I am not having much

success, since both openssl and openvpn only find the
first certifiacte in the ca specified file, which are surrounded in BEGIN,

END CERTIFICATE section headers 

Appreciate any help on this. 

Regards 

Sean
