Certificates and Connecting Securely to the WMI
When you point your browser to the Array to connect to the WMI, the Array
presents an X.509 security certificate to the browser to establish a secure channel.
One significant piece of information in the certificate is the Array’s host name.
This ties the certificate to a particular Array and ensures the client that it is
connecting to that host.
Certificate Authorities (CAs) are entities that digitally sign certificates, using their
own certificates (for example, VeriSign is a well-known CA). When the Array
presents its certificate to the client’s browser, the browser looks up the CA that
signed the certificate to decide whether to trust it. Browsers ship with a small set
of trusted CAs already installed. If the browser trusts the certificate’s CA, it
checks to ensure the host name (and IP address) match those on the certificate. If
any of these checks fail, you get a security warning when connecting to the WMI.
The Array ships with a default certificate that is signed by the Xirrus CA. You
may choose to use this certificate, or to use a certificate issued by the CA of your
choice, as described in the following sections:

Using the Array’s Default Certificate
The Array’s certificate is signed by a Xirrus CA that is customized for your Array
and its current host name. By default, browsers will not trust the Array’s
certificate. You may import the Xirrus certificate to instruct the browser to trust
the Xirrus CA on all future connections to Arrays. The certificate for the Xirrus
CA is available on the Array, so that you can import it into your browser’s cache
of trusted CAs (right alongside VeriSign, for example). On the
Management
Control
window of the WMI you will see the
xirrus-ca.crt
file. (
