Now, i belive this happens because that when Azure adds the Certificate to
my WorkerRole deployment, it do not install the certificate with the
option "Mark this Key as Exportable".
I need to add a certificate to my workerrole to beable to decypt a
encryptet setting.
Anyone have any ideas about how i can make Azure Mark the certificates
private key as exportable. or if it could be another issue.
