Well, we du run with valid thirdparty certificates that requires us to install a root-certificate.
But vCenter client works fine (without certificate warnings) before installing VSC module.
And its a lengthy process with administration to request for new certificates.
Haven't anyone stumbled on this problem while qualitytesting?
The certificate warning due to the VSC the first thing you see when you log into the vCenter client.
To make the thing worse, it seems that every client gets the VSC plugin running, no just those that actualy needs it (vSphere admins and Filer Admins).
