Digitally signing apps in RemoteApp on 2008 R2
I've just finished setting up our shiny new 2008 R2 Terminal Servers which are working fine for both Remote Desktops and RemoteApps. However, to configure single-signon for RemoteApps, the applications need to be signed with a digital certificate.
SSL certificates always give me a headache and I'd be grateful if someone could point me in the right direction. What type of certificate would I need to get for this purpose? FYI the RemoteApps functionality is to be accessed both internally and externally.
