Certificates that were imported via the certificate manager in the global security settings are
not automatically assigned to the corresponding modules. Imported certificates must be
included in the list of trustworthy partner certificates manually via the entry "Certificate
manager" in the local Security settings. When assigning a CA certificate the module is also
assigned the certificates derived from it.
