Changing the trust settings of an authority certificate
• Scroll to an authority certificate and select Options→ Trust settings.
Depending on the certificate, a list of the applications that can use the
selected certificate is shown. For example:
Application manager / Yes - the certificate is able to certify the origin of
new software.
Internet / Yes - the certificate is able to certify e-mail and imaging servers.
Important: Before changing these settings, you must make sure that you
really trust the owner of the certificate and that the certificate really
belongs to the listed owner.
