Search Appliance
Set this option to Y so that direct access to the admin
interface is only permitted via HTTPS and not HTTP. "Direct" means
the immediate, direct connection to the Search Appliance from the web browser
(or proxy, if any); security of the earlier hops of proxy-forwarded
connections is checked by Require HTTPS for Proxy Admin.
If you use this you must also turn on Enable HTTPS Server.
For safety, Require HTTPS for Direct Admin can only be enabled while
accessing the admin interface via HTTPS.
If you have set this option Y and accidentally configure it
such that you can not access the Search Appliance, you can re-enable HTTP
admin by going to the physical console of the Search Appliance and selecting
the drop Admin restrictions (HTTPS,IP,Cipher requirements)
option.
(Note: this setting was formerly called Require HTTPS Admin.)
