OpenProcess as the culprit: you do not have the rights to access your own process from the running code (might happen in webserver code)

That is unfortunately the static constructor of SAConnection so no way around it, it contains code to get the ProcessName of the current process and GetCurrentProcess() calls OpenProcess under the hood for which you need the appropriate rights.
