I have an ERP server hosted on RHEL 8.3, and for management I use cockpit portal from my web browser.
Everytime I enter to this portal I get a message saying the website is not trustable, and I want to remove it. This is the same problem I have with the web management portal of a TP-Link OC200 controller, and I suppose the same thing will happen if I try to setup a Windows Admin Center server too.
I have AD DS on my network thanks to a Windows Server 2016 Standard server with Essentials Experience running (with CALs and license all in rule), so I have AD CA too.
I googled that you can use this last role to resolve this little issue I'm dealing with, but because this is a production environment, I really don't want to mess up something. I want too to assign a forward address to the server, not only use server name or IP address, so I can type, for example, "myerp.local" on my browser, and enter the managing portal effortlessly.
I really don't have any experience with certificates neither managing DNS, so any help you can provide me will be appreciated.
Can you help me?
