Trust by Certificate. Sets HP SMH to accept configuration
changes only from HP SIM servers with trusted certificates. This mode requires
the submitted server to provide authentication by means of certificates.
This mode is the strongest method of security because it requires
certificate data and verifies the digital signature before allowing
access. If you do not want to enable remote configuration changes,
leave Trust by Certificate selected,
and leave the list of trusted systems empty by not importing certificates.
This is the default behavior on Linux Itanium.
HP strongly recommends using this
option because it is more secure.
