OESIS doesn't even mention anything about certs, except a line that says
GetActiveClientCertificates, (0 ms) result: Not implemented
It's the same whether the utility runs as a normal user, or the local Administrator user (Which I assume is equivalent of Unix/Linux root - I won't apologise for being a Unix/Linux guy and not windows. I'd probably seriously consider suicide if I had to work on windows every day).
Now whether this means OESIS doesn't do certs (Which seems strange since windows machine certs are documented as working on APM), or perhaps it's a windows thing (XP SP3 32Bit). I know the certs there, because the admins have shown me in some console interface they have.
