So you just upgrade to Exchange 2010 and you bought and installed your UCC certificate. Things look great right? But that was five months ago.
The SharePoint team called and they need an SSL certificate too. So can you use a UCC certificate? Yes, but it requires a lot more work. Oh, and the accounting department's web application, that can't handle Subject Alternate Names.
Time to call the aforementioned accounting department and get approval for purchasing that wildcard certificate. But the question is, do we just deploy it or setup Active Directory Certificate Services?
