Hey Baatezu,

My understanding is that you can buy a single wildcard cert that would allow you to secure any sub-domain at A.com (e.g. http://b.a.com, http://c.a.com). But that you cannot have one certificate for multiple top level domains. This isn't specific to DNN, .NET, Windows or anything - it's just "how it works" - I was looking around for a good web site that explains this with more detail but couldn't really come up with anything. Maybe someone else can provide us with a more in-depth explanation of why this is the case.

Take care,

Ian

 I did a little searching and there are certs out there for multiple domains on a single install - which I did know of (goDaddy has one) but they were small, 4 or 5 domains.

I found one for 25 domains at http://www.geotrust.com/ssl/multi-domain-ssl/, I don't know how many clients I'll have (the more the merrier) but I think this might work for a short term solution, and maybe I will just limit each DNN install to 24 clients (nobody gets 0, that's MINE!!!!).

P.S. I am in no way advocating or supporting using geotrust - That was just the first example of multiple domains on a single server above 5 that I found, so I posted the link to show something that is available.

EDIT - Oh... umm... godaddy does 100 domains on a cert... So... yea... apparently more than 5...
