We have a large number of engineers who are often dispatched to customer sites, and as such security of the machines becomes an issue. I wish that there was way to be able to use AD credentials to authenticate to open RoyalTS. If that is possible, then the second part would be to amend the ADMX file so that there was a GPO option to require users to authenticate using their AD creds when opening up Royal TS.
AD auth is currently not possible. We might be able to add this in the future. I strongly recommend that you encrypt and password protect your documents. This way, only a user who knows the document password can open it. You can also encrypt and password protect the "Application" document. Doing this, will prompt you for the app doc password when Royal TS starts.
