This object is the secret shared between the RADIUS
Accounting server and RADIUS client. This
parameter value is maintained across system reboots.
While the 'official' MAX-ACCESS for this object is
read-create, all security-conscious implementations
will 'lie' on a read, and return a null-string, or
something else that is fairly innocuous. The
ability to read back passwords and secret
encryption keys is generally a Bad Thing (tm).
