Cert updates for FMP9 and FMS9
The Mac download area has two SSL-related updates: FMP 9 SSL update
& FMS9 SSL update. I assume the PC side has similar ones.
But it's vague as to how they interact. I have appled the FMP one to new installations, as they will not connect otherwise. I've not applied the FMS one because of the fear such might lock out the non-updated clients.
They do not appear on the update prompt in FMP so I'm guessing they are "apply as needed" flavor.
