> The wsce-site.xml containes the impersonate.allowed and impersonate.denied keys that restrict/control the users that can be impersonated by the WSCE containers. The impersonation frameworks in winutils should validate that only Administrators have write control on this file. 
> This is similar to how LCE is validating that only root has write permissions on container-executor.cfg file on secure Linux clusters.
