Michael --
You're welcome.
Would a keyring with certificate issued by the Domino CA be acceptable for internal users accessing a site?
Absolutely.
I'm just wondering how many people are using the internal (Domino) CA vs. a 3rd party. I have always gone with 3rd party SSL certificates when external users accessed. If internal only and using LAN or VPN connection, I could see using the Domino CA process. What about internal users only accessing from the Internet?
If "external users" means the general public then it may make more sense to use third-party certificates instead of managing your own. But if your target audience is under your control (regardless of whether or not they access your servers internally or from the internet) as long as they're all able/willing to install your certificates, it probably makes better economic sense to create, manage and distribute your own (as Dave Kern from IBM points out in this thread). Domino is powerful enough to do this already so why pay a third party to do what you can do yourself at no additional cost?
