• If a certificate authority issues a certificate that must be authenticated by an intermediate certificate
authority, and
the certificate is installed on this machine, an intermediate certificate must be installed
on the client computer. Otherwise, validation by the certificate authority will not be performed
correctly. In this case, a warning message may appear when you try to add a printer using IPP-SSL
under Windows Vista/7, Windows Server 2008/2008 R2 or when the destination user receives an
e-mail with an S/MIME signature. A warning message might also appear if you attempt to access
this machine through Web Image Monitor with SSL enabled. To enable authentication from the client
computer, install the intermediate certificate on the client computer, and then reestablish connection.
• Intermediate certificates cannot be installed on this machine.
