converted to an error code and reported to higher-layer protocols via the return

cryptographic linked list of the memory representation of the store being
modified. It also writes through and saves the set to the disk. If called on an
online store, the method enumerates the connection security rules list and
reapplies each rule referencing this primary set to complete the enforcement of
the policy.</p><p>The server MUST determine whether the local computer is

If the local computer is operating in common criteria mode, the server MUST
