= Single User installation =
By default the QCG-Computing service must be started as `root` user (The service adhers the [http://en.wikipedia.org/wiki/Privilege_separation Privilege separation model]). If you do not have root access or you do not want to start the service as root for some other reasons you can configure the service to work in non-privileged mode (`qcg-compd.xml`):

{{{

...
</Database>
...
<UnprivilegedUser>current-user-name</UnprivilegedUser>
<SetuidEnabled>false</SetuidEnabled>

...
<FactoryAttributes>
...
}}}

However in such configuration you can run jobs **only** as a user who started the service.
