What happens when a customer changes his panel login in the control panel? Does this break the SSO?
No, the moment you establish the connection, we create an API key on the server through which we communicate with the server. If you delete the connection in PowerPanel the key will be removed.
Can PowerPanel be reached on SNI?
Is a paper trail included, so that we can see who edited what?
Yes, we have history logs. this logs can be accessed using the history option on the details pages in the Panel.
