Allow install of client CA certificates to the HMC to allow SSL proxy functionality.

Many organizations use proxy servers to control/manage external traffic. Some of these (Palo Alto Networks, for one) create a man-in-the-middle certificate so that SSL traffic can be proxied the same way as HTTP traffic. An example of this activity from the HMC is checking the "IBM Service Website" option when looking for available firmware updates. If the proxy uses an internal certificate not recognized by the HMC, the query will quietly (and instantly fail). A ticket to IBM reports that the ability to install a client-side CA certificate is not available, which means this functionality will break for many customers when the IBM switch to SSL/TLS only occurs later this year.

    Latest versions of HMC already has the capability to add trusted certificates. Please see the chhmccert command for details

    chhmccert -o add -t trustedcert -l trustedsslserver -a cmccert

    Add a certificate located on a trusted server and use a proxy connection with authentication:

    chhmccert -o add -t trustedcert -l trustedsslserver -a ssltestcert
    -h <hostname> --proxyserver <proxy serverip:port>
    --proxyuser userID --proxypasswd password

    Remove a trusted certificate:

    chhmccert -o remove -t trustedcert -a cmccert
