Our environment has over 5 Sophos UTMs, managed by SUM. How do I configure the Client Authentication Agent so that when people go from one office to another they do not receive this message?
Do I 'pick' a certificate and install it at the SUM, then push it out to all the Sophi so that everyone has the same one? How does that work if each Sophos UTM has a unique fqdn for their site? Is there a whitepaper or best practice document I have not read out there somewhere that tells me what I should do.
