I'm a certificate noobie, so please forgive me.
I've created a self-signed certificate through ADFS 2.0 and I have my SP2010 site trusting that cert for SSL sign-in. I can access my site fine but I always get certificate warnings through my browsers that I use. For some reason I can login with IE and Firefox, but not Chrome... but that is probably another issue. In order to have those certificate warnings go away, I need to get a CA certificate, correct? It's pretty annoying to have those warnings always hit you when you go to sign into your sharepoint site and your address bar is red.
