Restarting the server as part of the command to add and remove certificates gives an error on RHEL 7

When the external certificates are added to Access Appliance, a web server restart is implicitly performed to start the newly provided certificates. This implicit start of the web server does not work in RHEL 7 because the commands are different in RHEL 6 and RHEL 7.

(IA-9739)

Workaround:

Run the System> guienable command to start the server in the Access Appliance command-line interface.
