### 2. Create a sample OPA Policy

In another terminal, create a policy that allows root user all access and for all other users denies `PutObject`:

```sh
cat > example.rego <<EOF
package httpapi.authz

import input

default allow = false

# Allow the root user to perform any action.
allow {
 input.owner == true
}

        // Count how many registrations this affects
        int affectedRegistrations = 0;
        for (MockRegistration reg : registrations.values()) {
            if (reg.shareName.equalsIgnoreCase(resourceName) || reg.serverAddress.equals(resourceName)) {
                affectedRegistrations++;
            }
        }
